Retinol Therapy with Antioxidant and Anti-Inflammaging Complex Combined with Microneedling Therapy for Hyperpigmentation and Acne Scars in Patients with Skin of Color: A Pilot Case Study

Background: Dermatology and aesthetic medicine make extensive use of microneedling, a minimally invasive and safe treatment. Across the research, it has been shown that microneedling combined with chemical peels is also more effective than chemical peels alone. However, data on procedures in dark-skinned individuals is rather scarce. Aim/Objective: This study aimed to determine the efficacy of using a 4% retinol solution product containing novel TGF-β activators and antioxidants combined with a microneedling technique in the treatment of hyperpigmentation, atrophic acne scars, and enlarged pores in patients with skin of color, generally corresponding to Fitzpatrick skin phototypes IV–VI. Methods: Each of the 10 patients underwent three peel treatment series, with a 30-day interval between each session. Moreover, skin hydration, elasticity, and pigmentation were examined using the Multi Skin Test MC 1000 Courage + Khazaka, and the Observ 520x device. Results: All patients reported an overall improvement and an enhancement in skin tone after the procedure. The majority of them stated subjective improvement in the reduction of facial skin issues: redness, hyperpigmentation, uneven structure, wrinkles, dehydration, dryness, and sebaceous gland activity. The least improvement was noted in scar reduction or liquidation. An objective evaluation revealed a statistically significant improvement in hyperpigmentation and elasticity in the study group. An improvement, however, not statistically significant, in hydration parameters was demonstrated during the study. Conclusions: This study suggests that a combined peel therapy of 4% retinol serum product containing novel TGF-β activators and antioxidants, together with a microneedling technique, may improve facial hyperpigmentation of the skin, as well as regulate sebaceous gland activity, their size, and reduce sebum production. The recommended method is relatively simple to use, low-cost, has minimal adverse effects, and is well tolerated by patients with skin of color.
