BACKGROUND:

Seborrheic dermatitis (SD) is a chronic mild skin disorder with high prevalence. Various treatment options are available, including topical antifungals and anti-inflammatories. Antifungal and anti-inflammatory properties of Quassia amara have been reported.

AIM:

To check the efficacy and safety of a topical gel with 4% Quassia amara extract and compare it with topical 2% ketoconazole and 1% topical ciclopiroxolamine in the treatment of facial SD.

METHODS:

A group of 60 patients displaying facial SD were randomly distributed in 3 groups and given either a topical gel with 4% Quassia amara extract, a topical gel with 2% ketoconazole, or a topical gel with 1% ciclopirox olamine for 4 weeks. Disease severity was assessed at the start and weekly along treatment, as well as 4 weeks after the end of treatment. In each selected area, severity of erythema, scaling, pruritus, and papules were scored from 0 to 3, the sum of these values representing the score of SD on the face. This evaluation was conducted at each visit. The decrease in SD score with all 3 products was compared at each visit. At each stage, overall improvement, safety, and tolerability were also assessed.

RESULTS:

Of the 60 patients, 54 (90%) completed the study. The 3 therapeutic options resulted to be very effective, with a significant advantage in efficacy for 4% Quassia extract. For the other 2 drugs, the results were in line with those previously published in the literature.

CONCLUSION:

Topical gel with 4% Quassia extract represents a new, safe, and effective treatment for facial SD.
