Introduction
Several options are available to treat acne lesions, including topical benzoyl peroxide, topical retinoids, topical antibiotics, oral antibiotics, hormonal therapy, isotretinoin, and procedural therapies, such as light and laser therapies, although these cause side effects. This study aimed to establish the efficacy and tolerability of a class IIa medical device containing lactic acid, azelaic acid/polyglyceryl-3 copolymer, azelamidopropyl dimethyl amine, and bifida ferment lysate for the treatment of mild and moderate acne lesions.
Methods
A randomized, double-blind, placebo-controlled, multicentric study was carried out in which 60 persons of both genders aged ≥ 16 years affected by mild or moderate acne were enrolled. Each person used the product twice daily for 2 months. The clinical score (classified as absent, mild, moderate, and severe) of lesions such as blackheads, whiteheads, papules and pustules, erythema, desquamation, sebum secretion, and porphyrins production by a wood lamp was evaluated on the basis of a dermatologist’s visual assessment at baseline (t0) and after 2 months of treatment (t1), and the results were compared between groups. Digital photographic images were also taken.
Results
Sixty subjects concluded the trial. It was observed that subjects treated with the medical device (group I) showed overall improvement in the analyzed acne lesions compared with placebo (group II) after 2 months of treatment. The efficacy of the treatment was also expressed as partial and total clearance. The medical device produced higher percentages of both partial and total clearance in all analyzed parameters, compared with the placebo group. The study was safe and well tolerated.
Conclusions
It was observed that the participants showed an overall improvement of the analyzed lesions in comparison with the placebo group, without adverse events during the trial. Hence, the medical device was found to be safe and effective in the treatment of mild or moderate acne.
