  1. Antonia, 

    The general consensus is that the mites on cats or dogs are a different species, however, as pointed out above, scabies and other demodex can infect a human from a pet. There should be more research on this but as it stands now the data shows that the species of mites on humans are different than on pets, generally speaking. Each mammal usually has its own species of demodex mites. The point of this post is that since we do know that mites can travel from pets to humans, there is a possibility that demodex do indeed infect humans from pets. You certainly don't want to be infected with scabies

    Hello thank you for replying. I just ate a Blueberry Kind Bar and got red blotchy cheeks, so much for "good grains". I tried Finacea, Mirvaso, trying Soolantra all generic brands. Natural products I tried pumpkin seed extract, licorice root, Madagascar Centella, vitamins a thru all. I am not sure I have those 2 autoimmune diseases but a skin doctor told me maybe I have one of those too being I flare get red no matter what I eat and even if I dont eat I sit at work and can get red for mo reason (not stress). I am taking Doxycycline right now my doctor tried to switch me over to Minocycline which was a nightmare my skin freaked out so I am back on Doxycycline. I cant even find a local doctor to help or make a diagnosis if I have them besides Rosacea. I am premenopausal and I hear that as a excuse from doctors. I dont see why no matter what I do or dont do my skin is like this. I wil try no sugar.

    Not sure which Blueberry Kind bar you are eating but I found the above Nutrition Facts Label to show you how much carbohydrate is in this bar which shows 24 grams in a 35 gram serving. You can subtract the 2.5 grams of dietary fiber since fiber has no significant energy to consider.* So technically the above serving is 21.5 grams of carbohydrate in a 35 gram serving. That means this bar is 61% carbohydrate. This is a high carbohydrate food. When you carefully go through the Nutrition Facts Label for everything you eat in a day, you are probably, without a doubt eating a high carbohydrate diet. There is ample evidence that sugar/carbohydrate is a rosacea trigger in anecdotal reports. For that matter, any proposed rosacea trigger is based upon surveys or anecdotal reports, therefore, listing sugar/carbohydrate as a rosacea trigger is just as valid as any other proposed rosacea trigger, no matter who makes the list. 

    So usually the question is what should you eat for thirty days to see if reducing sugar/carbohydrate improves your skin?  Eat high protein and fat. Eating high protein/fat for thirty days poses absolutely no health risk contrary to what you might learn from any source. After the thirty days you can then decide based upon what you learn whether this improves your rosacea and other issues. This will not be easy because sugar is an addiction. So you simply have to balance whether having your skin issues improve is worth the effort to get off of sugar for just thirty days. 

    Also since you are taking doxycycline, you will need to build up your good flora with probiotics, which is now an accepted medical treatment for rosacea. Short term antibiotics for rosacea may be required to control rosacea, but long term antibiotic treatment for rosacea can produce some unwanted side effects and risks. You need to decide whether taking long term antibiotics are worth those side effects and risks. Probiotics offer an alternative. 

    How long did you use Soolantra? Why did you stop using it? 

    It is good you are taking supplements, herbals and vitamins. Have you read this post?

    Don't give up, you will find a way to control your rosacea and other issues. 

    *To learn why fiber is not a significant source of energy, read the article, Carbohydrate Not Essential For Human Survival

    The human microbiome includes the skin which contains a number of different microbes. [1] One microbe that has generally been totally ignored is archea, which has never been ruled out as having anything to do with rosacea.

    "Methanobrevibacter smithii is the predominant archaeon in the human gut."

    The general public has little if any knowledge of this microbe which has been known to exist in the human microbiome for some time now. "Archaea are a major part of Earth's life. They are part of the microbiota of all organisms. In the human microbiota, they are important in the gut, mouth, and on the skin. They may play roles in the carbon cycle and the nitrogen cycle." [2] The chief reason that archea is basically totally ignored as having anything to do with rosacea is that there is no known archea human pathogen. Furthermore, due to the bias the scientific community has towards bacteria which focuses research on bacteria ignoring most of the other microbes, including archea, little is known about archea.   

    "A deeper knowledge of human microbiome composition and microbe-host interactions will contribute to clarify the mechanism of development of rosacea and possibly will provide innovative therapeutic approaches." [3]

    Basically we have no idea what role archea plays in the skin microbiome due to a lack of investigation into this subject. Hence, little is known of what role archea may play in rosacea. There is absolutely no motive to investigate this since who would fund such a study? Hopefully someday some research will discover the role archea plays in the human microbiome and whatever revelations are discovered may alter our understanding of archea. 

    Do you want to fund such a study? Could 10K members of the RRDi get together and each donate one dollar to fund such a study? Only with your help could we reach such a goal. Think about it. [4]

  4. A paper written in 2017 about diet and rosacea never once mentions sugar/carbohydrate as a rosacea trigger and parrots the diet triggers promoted by the NRS while admitting that "Dietary triggers are also frequently cited by patients, although there is a lack of research in this area. In one survey by the National Rosacea Society of over 400 patients, 78% had altered their diet due to rosacea. Of this group, 95% reported a subsequent reduction in flares." The NRS has never listed sugar/carbohydrate as a rosacea trigger, even though the number of anecdotal reports continue to grow that indeed sugar/carbohydrate is just as valid a rosacea trigger as any of the other NRS proposed triggers. The paper about diet and rosacea is cited below:

  5. Welcome to the RRDi community support. If you are suffering from rosacea plus gastatory face flushing* and erythromelagia, we can only empathize with your situation. Your condition is extreme and quite unusual. Not many rosaceans are suffering as much as you are suffering. Have you tried avoiding sugar and carbohydrate or at the very least reduced your intake to see if this improves your situation? Sugar is the fire that burns rosacea. It is not expensive to avoid sugar, in fact, you will save money avoiding sugar. Basically, all you do it eat high protein/fat for thirty days to see if your skin improves. Eating high protein/fat for just thirty days and drinking lots of water is not a health risk since it is only temporary. You may learn that you need more protein/fat instead of the high sugar/carbohydrate to control your rosacea. For example, you may not know how eating macaroni and cheese is a high carbohydrate meal. Our bodies are mostly water, protein and fat and carbohydrate only takes a very small percentage of our body mass. It is simply something that you can rule out to see if this helps your skin. 

    In order to recommend topicals, we would need to know what topicals you have tried. Also what oral medications or vitamins/supplements or any other oral treatments have you tried? 

    How long have you been suffering from this?

    Protozoa and rosacea has not been considered in any clinical paper known to date. However, there is a "link between protozoa, vitamin B12 deficiency, acne and depression" according to at least one clinical paper. [1] This same source states the following about rosacea: 

    "Rosacea is another inflammatory skin disease that causes facial redness but it is different from acne, the common denomination being inflammation. Metronidazole, a synthetic antibacterial and antiprotozoal agent of the nitroimidazole class, is used against protozoa such as Trichomonas vaginalis,  amebiasis, and giardiasis. Metronidazole is extremely effective against anaerobic bacterial infections and is also used to treat Crohn’s disease, antibiotic-associated diarrhea and rosacea. The nitroimidazoles class of agents used to treat G. lamblia infection includes metronidazole, tinidazole, ornidazole, and secnidazole. This class was discovered in 1955 and was found to be highly effective against several protozoan infections." [1]

    "Protozoa constitute a group of microorganisms, also known as protists, some of which are responsible for serious diseases in humans, such as malaria and Chagas' disease and inflammatory disease conditions." [1] A significant number of deaths due to diarrhea are caused by three protozoas - Entamoeba, Cryptosporidium, and Giardia. 

    The human microbiome includes a number of different microbes, including protozoa. The NRS substantiates that protozoa are included in the human microbiome by publishing this statement,  "Microbes include bacteria, fungi, protozoa [bold added] and others, and may be found in greatest concentrations in the ears, nose, mouth, vagina, digestive tract, anus and the skin." [2] Very little is known about protozoa and rosacea. What exactly are protozoa?

    "Protozoa (also protozoan, plural protozoans) is an informal term for single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Historically, the protozoa were regarded as "one-celled animals", because they often possess animal-like behaviors, such as motility and predation, and lack a cell wall, as found in plants and many algae.  Although the traditional practice of grouping protozoa with animals is no longer considered valid, the term continues to be used in a loose way to identify single-celled organisms that can move independently and feed by heterotrophy." Wikipedia

    Treatment Used for Malaria Have Proved Successful in Rosacea
    There has been some treatments for malaria [protozoa] that have been used to treat rosacea such as mepacrine, chloroquine, and hydroxychloroquine that have proved successful in some rosacea patients.  

    Protozoa has never been ruled out as having a connection with rosacea. There simply isn't much data on this subject. 

    There needs to be more clinical studies done on protozoa and rosacea. Since protozoa has never been ruled out in causing rosacea, who would support such an investigation? Would you? Just think if 10K members of the RRDi each donated one dollar and insisted on supporting a reputable clinician to study protozoa and rosacea, what might be discovered?

    Yes I know this very well it has its medicinal properties and used for food and pharmaceutical industry considering its compounds but not much research has been done on this plant when it comes to skin diseases especially for rosacea and the link you provided It is already mentioned in my articles reference note. Yes you can not find the essential oil online that is why how I made this concoction oil I have explained this in my article.

    I hope others try this. I was just pointing out I couldn't find any essential oil available. Are the leaves available for purchase somewhere?

  8. mepacrine.jpg

    There are some papers indicating using mepacrine for the treatment of rosacea. One paper published in The Lancet, May 1952 written by Borrie Peter and another paper published in 1955.  Another paper mentions using mepacrine and chloroquine in combination to treat rosacea. [1] Scarlet Letters has an interesting article discussing using mepacrine and plaquenil in treating rosacea.

    I would like all of you to test this natural extract for your rosacea inflammed skin. Its extract has high antimicrobial and anti-inflammatory effects and has shown some strong effects towards some bacterial species found on skin. You can use it as a pure essential oil or better make a concoction with your preferred oil. Your contribution would mean a lot and help me recognize my work and research on this. I am soon coming with other natural products for rosacea. Comment your experience.

    "Considering properties of the identified major compounds, essential oils of both studied myrtaceae could be used in the medicine field including the food, pharmaceutical and cosmetic industry." 

    Amazon doesn't sell Callistemon viminalis essential oil. A google search doesn't show how to purchase it either. Maybe someone can find it?


  10. A recent study published International Immunopharmacology that hydroxychloroquine "improved rosacea in rosacea-like mice and mast cells (MCs)" and investigated "the effects of HCQ treatment for rosacea patients". The paper concludes, "In vitro, HCQ suppresses LL37-induced MCs activation in vitro, including the release of inflammatory factors, chemotaxis, degranulation and calcium influx. Moreover, HCQ attenuated LL37-mediated MCs activation partly via inhibiting KCa3.1-mediated calcium signaling. Thus, these evidences suggest HCQ ameliorated rosacea-like dermatitis may be by regulating immune response of MCs. Finally, the 8-week HCQ treatment exerted satisfactory therapeutic effects on erythema and inflammatory lesions of rosacea patients, indicating that it is a promising drug for rosacea in clinical treatment."

    Since hydroxychloroquine is available worldwide in generic form we should hear more reports from rosaceans who will ask their physician for a prescription to confirm these results. Duff Man reported in 2017 that this worked for him. Another thread at RF in 2010/2011 has a few others who have tried it discuss their experience. antwantsclear [post no 240 and post no 243] reports taking hydroxychloroquine starting in 2011 and continues to use it for flushing. 

    One paper published in the Archives of Dermatology, January 2011, indicates that 3 out of 5 patients with neurogenic rosacea were successful using hydroxychloroquine. 

  11. Duff Man told us in 2917 that Plaquenil (Hydroxychloroquine) which has been used to treat lupus works for rosacea. A recent paper published confirms this and states, " Finally, the 8-week HCQ treatment exerted satisfactory therapeutic effects on erythema and inflammatory lesions of rosacea patients, indicating that it is a promising drug for rosacea in clinical treatment." Since Hydroxychlorquine is available in a generic prescription and is available around the world in such brand names as Plaquenil, Hydroquin, Axemal, Dolquine, Quensyl, and Quinoric rosaaceans can refer to this paper and ask their physician for a prescription for an eight week course. We should be hearing reports whether more report success with this treatment. 

    Hydroxychloroquine Suppresses LL37-induced Mast Cells


  12. A paper published in the British Journal of Dermatology concluded that after treatment with 1% and 3% Minocycline Topical Gel, this resulted with a "significantly decreased inflammatory lesion counts and a significantly larger proportion of subjects achieved IGA success at week 12 in the 3% topical minocycline group. These findings support further evaluation of minocycline gel for the treatment of inflammatory lesions associated with papulopustular rosacea."

    Metronidazole will be having some competition. 

  13. Dry skin (Xeroderma) can be a co-existing condition with rosacea. When treating rosacea with topicals or oral treatments, a common side effect is dry skin, and if one already has dry skin, this complicates the dry skin issue further. Women's Health has an article on treating dry skin using The Inkey List treatments and has this to say about the subject: 

    "Dry skin needs – you guessed it – serious hydration."  

    The following four treatments are recommended: 

    (1) Polyglutamic Acid

    {2} Squalane Oil (contained in this package below}

    (3) Rosehip Oil 

    {4] Lactic Acid

  14. Time to review the 2018 Form 990 the NRS publishes on their website or you can read for yourself below: 



    Let's first try to concentrate on the positive aspects of this report. The NRS is the leading non profit organization for rosacea that supports research grants for rosacea. In 2018 a total of $12,500 was spent on research grants if you read Form 990, Part IX, Line 1. How can you figure out who received the $12,500?  You definitely have to do some digging since the Form 990 doesn't disclose this. The NRS website in its Awarded Grants page shows Dr. Anna Di Nardo and colleagues were awarded $25,000 in 2018. In reviewing the Form 990 it does indeed show that $25,000 was awarded to the Regents of UCSD shown below: 


    So let's give the NRS a benefit of doubt and instead of $12,500 which is shown on Form 990, Part IX, Line 1, and commend the NRS for spending $25K for rosacea research grants. This means that the NRS spent 5.37% of its donations in 2018 on rosacea research. 

    Putting into Perspective How the NRS Spends Donations

    2018 donations were down from previous years with a total revenue of $465,042 (in the 21 years I have been following the NRS Form 990s, 2001 was the only year lower in donations). While acknowledging above that the NRS spent $25K for rosacea research, putting this into perspective is the fact for every dollar donated to the NRS in 2018 only a little more than a nickel (5 cents) was actually spent on rosacea research. What was the rest of the donations spent on? Answer: 

    93% of the donations were spent on two private contractors that are owned by the president/director of the NRS Sam Huff. Here is a screen shot of the names of the two private contractors shown on Form 990: 


    How do we know that Glendale Communications Group, Inc and Park Mailing and Fulfillment, Inc belong to Sam Huff?  The Illinois Secretary of State gives the proof. As you can see from the screen shot above, Form 990, Schedule R, Line 2 shows the amount sent to these two corporations which is $432,408. Is this legal? Yes, of course. You didn't know that NON profit corporations can do this? If you want an education, read this post

    Here is a screen shot of Form 990, Part VII, Section A, Compensation which is interesting: 


    I didn't know that Zoe Draelos, MD who also serves on the RRDi MAC is now serving on the board of directors for the NRS. She received $2500 from the NRS in compensation. Good for her! Also Dr. Gallo who I have tried to contact to serve on the RRDi MAC to no avail also received $2500. Good for him!  Did you note how much Sam Huff receives? The RRDi would love to give Dr. Draelos $2500 but we didn't even receive half that amount in donations so all we can do is keep our website going and keep the RRDi afloat since our donations are quite meager compared to the donations given to the NRS.  

    One other very interesting item on the 2018 Form 990 the NRS has released is the amount of Excessive Contributions which has never been revealed in the twenty years I have been following NRS Form 990s. See below: 



    If you note the screen shot above it says **Do Not File** ***Not Open to Public Inspection*** which if I had paid accounting fees of $26,691 to my accountant as shown on the NRS Form 990 for 2018, Part IX, Statement of Functional Expenses, Line 11, c, it would pose a question why is this made public? We have never before had any indication the amount of donations the pharmaceutical companies give to the NRS. And if you note in Form 990, Part VI, Governance, Section B, Policies, Line 11a, please note the question, "Has the organization provided a complete copy of this Form 990 to all members of its governing body before filing the form?" and also note that 'yes' was checked. This is also restated in Form 990, Schedule O, where is shows the following: 


    If the pharmaceutical companies discover that the NRS has disclosed its Schedule A,  IDENTIFICATION OF EXCESS CONTRIBUTIONS, what might the consequences of this be?  I find it odd in the first place that 501 c 3 non profits are not required to disclose the identification of who is donating when it is obvious they are private contributions and not pubic donations. However, you know who makes the IRS rules for non profits? Probably nothing will become of this disclosure but I find it really interesting. 

    The only other interesting item I found was that the NRS reports an expense of advertising in the amount of $74,814 (Form 990, Part IX, Statement of Functional Expenses, Line 12. It also reports on Form 990, Part VIII, Statement of Revenue, Line 2a, Advertising Income in the amount of $85,000. I don't recall seeing any advertisements on the NRS website, but maybe I am missing something?  I wish I could figure out how to get advertising income for the RRDi. Does anyone know how this is done? Sure could use some help.

    If you are having any issues with the above two steps CONTACT us describing your issue. 

  16. Just an update on my venting in this thread, which started on April 8, 2019 (264 days this thread has been up and running) which now has 299 views as of this date (December 28, 2019). I have moved to Alabama and have begun going through the process of registering the RRDi in Alabama which is odd, because I recall one of the members of the board of directors for the Rosacea Research Foundation was a veterinarian living in Alabama. Very few rosaceans will recall all those events back in 2004 when two non profit organizations went in two separate directions. The RRF dissolved but David Pascoe still maintains its website and has now removed the names of those who served on the board of directors. 

    So I put out a request for any member of the RRDi who lives in Alabama to come forward and volunteer to sit on the board of directors and Johannes Schild has filled that spot so that we have two members on the board who are residents of Alabama. We could also continue to be registered in Hawaii if any RRDi member would volunteer to do that, but since volunteering is usually something that our RRDi members shy away from, I doubt if that would ever happen. I personally knew a friend in Hawaii who has rosacea and asked her to do that but she told me she was also leaving Hawaii next year and couldn't volunteer. So if anyone wants to keep the RRDi registered in Hawaii it would be good to contact me asap. 

    So this thread has had an average of just a little over 1 view a day since I initially posted my vent. Not too many care about reading my vent, and at least Apurva has replied to this thread (and I am happy for almost 300 views). However, I will continue my vent. Could one of you who reads this thread explain to me why you think hardly any of the RRDi members don't want to post in the public forum?  Why would 1200 plus members join the RRDi and then NEVER post? What is going on? 

    I thought since Facebook and Reddit were PRIVATE (social media groups for rosacea) and for some reason rosaceans prefer to be in private groups, the RRDi has sponsored a private rosaceans group but that has NOT been popular at all. We are spending $10/month to do this and it sure hasn't been used at all. I was thinking about making the public member forum we use through Invision Community into a PRIVATE forum. What are your thoughts about this?  

    The RRDi does have Facebook and Reddit groups but that hasn't proved popular at all. What are your thoughts about all this? Why the lack of posting by RRDi members?

  17. 314px-Demodex_mite_1.jpg
    Demodex Canis image courtesy of Wikimedia Commons

    Most clinical papers on rosacea refer to only two demodex mite species found in humans, demodex folliculorum and demodex brevis. For example, Wired magazine in its article on demodex reports, "Our network of skin caverns offers food and shelter to two different species of mites: Demodex folliculorum and Demodex brevis." However, there are a large range of demodex mite species (one source says, "approximately 50,000 species have been described" [1]). 

    In dogs there are at least three types of demodex, Demodex canis, D. injai and D. cornei. [2] There are different species of mites living on birds and rodents. In fact, just about all mammals have some species of demodex mites living on them. Can any of these mites, especially on pets transfer to humans? 

    The answer is yes. 

    "Human infestations with mites such as Cheyletiella and Sarcoptes scabiei are reported occasionally. The transmission rate for S scabiei var canis from dogs to people is estimated to be 10-50%, and close, prolonged skin contact is the most important route of transmission. Cheyletiella mites from animals are also reported to bite humans readily; however, clinical signs may not be common, or possibly not recognized. One source estimates that approximately 20% of pet owners with Cheyletiella- infested animals are affected. Not all mites, even those known to have zoonotic potential, will readily infest people. For example, human infestations with species such as Ophionyssus natricis or Lepoacarus gibbus appear to be uncommon." [1]

    "A twenty-year-old girl student who feeds a Miniature Pinscher crossbred dog in her house for a while noticed common itchy papulopustular lesions, incrustation and some alopecic loci in her dog and admitted to Selçuk University Faculty of Veterinary Medicine, Department of Parasitology. Itchy papules and pustules were also observed in dog's owner face and arm about three or four weeks later. Skin scrapings and hair samples were taken from the patient and the dog and examined with light microscope. Adult and egg forms of Demodex spp. were detected in both patient and dog specimens in microscopic examination." [3]

    "Mange is a skin disease that is caused by two different species of mites. Sarcoptic manage is caused by Sarcoptes scabiei. Demodectic mange can be caused by several mites of the Demodex family. Sarcoptic mange is extremely itchy and highly contagious to other animals and humans. Demodectic mange is not as itchy, and while is can be transmitted to other dogs, it is not contagious to humans or cats." [4]

    "Scabies, an infestation by the itch or scabies mite, Sarcoptes scabiei var. hominis, remains a major public health problem worldwide and a common cause of PUO in returning travelers. The worldwide prevalence of scabies has been estimated to be about 300 million cases/y.  Although more often associated with crowding, homelessness, institutionalization, and immunodeficiency, scabies occurs worldwide in both sexes, at all ages, and among all ethnic and socioeconomic groups." [5] "Sarcoptes scabiei or the itch mite is a parasitic mite (an arthropod) that burrows into skin and causes scabies. The mite is found in all parts of the world. Humans are not the only mammals that can become infected. Other mammals, such as wild and domesticated dogs and cats (in which it is one cause of mange) as well as ungulates, wild boars, bovids, wombats, koalas, and great apes are affected." Wikipedia

    Generally speaking it is rare for humans to contact mites from pets, but it can happen as the above sources are cited as sources. Usually, the only species of demodex mites found on humans are demodex folliculorum and demodex brevis, but in rare cases other species are found, with the exception of scabies as noted above which effects millions.

    The RRDi is the only non profit organization for rosacea that lists sugar and carbohydrate as rosacea triggers (see the RRDi Trigger Factor List). Search all you can and you won't find either one listed on the other non profits for rosacea trigger lists. Why do you think this is the case? 

    There is ample anecdotal evidence from rosacea sufferers that reducing sugar and carbohydrate in the diet improves rosacea while ingesting huge amounts of sugar and carbohydrate triggers rosacea. Trigger factors are simply discovered by anecdotal reports from rosacea sufferers in surveys and polls. 

    What many rosacea sufferers don't understand is that sugar is carbohydrate, which is simply carbon plus water. There are absolutely no essential nutrients in carbohydrate, none. Increasing sugar/carbohydrate into your diet is a rosacea trigger. Sugar is the fire that burns your rosacea, the fuel for your inflammation. High Sugar Content Leads to Inflammation.

    If you are skeptical about this why not try eliminating or reducing sugar/carbohydrate in your diet for 30 days and see if your rosacea improves. Then eat a significant amount of sugar/carbohydrate in the diet after this 30 day experiment and notice what happens. Most rosaceans will not try this simple experiment to see if sugar/carbohydrate is triggering rosacea because most are addicted to sugar. Yes, sugar is an addition. For those septics, they will have to find another way to control their rosacea. 

    Trigger avoidance is an accepted medical treatment offered by most physicians who parrot the NRS Trigger Factor List. However, you will be hard pressed to find a physician who parrots the NRS Trigger Factor List to mention you should avoid sugar/carbohydrate. The RRDi Trigger Factor List is much more extensive and continues to grow as more anecdotal evidence comes in from rosacea sufferers. Just picture in your mind that sugar is the fuel that is burning your rosacea. If you reduce the fuel that is burning your rosacea, you will help put the rosacea fire out.
