Recommended Posts

A clinical study has confirmed that the most common allergens rosacea patients suffer contact dermatitis are the following ingredients: 

Octyl Gallate

Dodecyl Gallate



Euxyl K400 (Methyldibromo glutaronitrile)

Cocamidopropyl betaine (CAPB)

2,6-Di-tert-butyl-4-cresol (Butylated hydroxytoluene)

The study concluded, "This study shows that rosacea patients show a strikingly high prevalence of contact sensitization to cosmetic allergens. We recommend the additional use of cosmetic series for patch testing, and the careful use of cosmetics in rosacea patients if cosmetic contact sensitivity is suspected." [1]
