Purpose: The present study aimed to evaluate the efficacy of an oxybrasion treatment applied alone and an oxybrasion treatment combined with cosmetic acids in improving acne-prone skin and selected skin parameters.
Patients and methods: A single-blind placebo study in a sample of 44 women diagnosed with acne vulgaris was conducted. Group A (n = 22) had a series of five oxybrasion treatments, while group B (n = 22) received a synergy of five oxybrasion treatments and a mixture of phytic, pyruvic, and lactic and lactic ferulic acids at 40% pH 1.4. Cosmetic treatments were performed every 14 days, and The Derma Unit SCC3 apparatus (Courage & Khazaka, Cologne, Germany) Sebumeter SM 815 and Corneometer CM825 and GAGS scale were used to check their effectiveness.
Results: A Bonferroni post hoc test showed that group A and B did not differ from each other in acne severity before treatment (p = 1.00). However, these samples differed significantly after treatment (p < 0.001), suggesting that combined treatment of oxybrasion and cosmetic acids has a better effect than oxybrasion alone. Also, two treatment conditions (before and after) were statistically different for groups A and B separately (p < 0.001), indicating a similar efficacy of both treatments on acne severity.
Conclusion: Cosmetic treatments improved acne-prone skin and selected skin parameters. Better results were obtained by combining an oxybrasion treatment with cosmetic acids.
Clinical trial approval: The clinical trial with ID ISRCTN 28257448 approved this study.
