Successful treatment of the face post acne erythema using a topically applied selective alpha 1-Adrenergic receptor agonist, oxymetazoline 1.5%, a controlled left to right face comparative trial.

BACKGROUND

Post-inflammatory erythema (PIE) is a common sequalae of acne inflammation, persistent post acne erythema (PAE) is cosmetically unacceptable and sometimes its complete clearance could not be achieved. Oxymetazoline (OXZ) is a synthetic, direct-acting, sympathomimetic agonist that is highly selective for the 1α-adrenoceptor. It is a potent vasoconstrictor and well known for its ability to clinically 'get the red out'.

AIM

The aim of this study was to evaluate the efficacy and safety of topical oxymetazoline (OXZ) 1.5% in treatment of post acne erythema (PAE) in a left to right face comparative study.

METHODS

This study was conducted on 40 patients diagnosed with post acne erythema for at least 3 months, the left side of the face was treated with topical OXZ 1.5% in liposomal base and was compared to the right side to which topical lipogel was applied as a control.

RESULTS

According to the investigator's global assessment of photographs and the analysis of erythema with image analysis software, topical OXZ was significantly effective in diminishing PAE when compared to topical placebo lipogel.

CONCLUSION

Topical OXZ is a safe and effective treatment for post-acne erythema.
