BACKGROUND: persistent post acne erythema (PAE) is a common cosmetically unacceptable and challenging sequelae of acne lesions. Tranexamic acid (TXA) is an antifibrinolytic agent that shows a positive effect on wound healing in several studies, and it showed benefits in treating skin diseases like melasma, rosacea erythema and ultraviolet induced pigmentations. Oxymetazoline (OXZ) is a synthetic, highly selective agonist for alpha 1A-adrenoceptor. It is a potent vasoconstrictor. Oxymetazoline hydrochloride 1% cream was approved by the FDA in January 2017 as a topical treatment for persistent facial erythema in rosacea patients. Brimonidine tartrate (BR) is highly selective α2 adrenergic receptor agonist, results in direct, potent vasoconstriction of small arterioles and veins. In 2013, brimonidine 0.33% gel was the first topical therapy to be FDA approved for the treatment of persistent facial erythema from rosacea.

OBJECTIVES: to evaluate the efficacy and safety of topical triple combination (TXA 5%+OXZ 1.5%+ BMT 0.33%) in the treatment of post acne erythema (PAE) planned as split face comparative study.

METHODS: This study was conducted on 40 patients diagnosed with persistent post acne erythema for at least 3 months, the right side of the face was treated with topical triple combination in liposomal base and was compared to the left side to which topical lipocream (placebo) was applied as a control. Our treatment plan lasted for 3 months.

RESULTS: According to the investigator's global assessment of photographs and computerized analysis of erythema using image analysis software, topical triple combination applied o the right side of face was significantly effective in diminishing PAE when compared to topical placebo left side.

CONCLUSION: topical triple combination is a safe and cost-effective treatment for post-acne erythema.
