Issues of therapy for post-acne post-inflammatory hyperpigmentation

Abstract

Introduction. Post-acne post-inflammatory hyperpigmentation most often develops in patients with moderate to severe acne. Post-acne pigmentation can be persistent and last from months to several years, which has a negative impact on the patients’ quality of life. It occurs at any age with the same frequency in men and women.Aim. To evaluate the effect of dermatocosmetic products – a triple effect serum (containing thiamidol, salicylic acid and lycochalcone A) and SPF30 fluid for problematic skin on the skin condition in patients with moderate and severe post-acne post-inflammatory hyperpigmentation.Material and methods. A total of 57 patients with post-acne post-inflammatory hyperpigmentation localized on the facial skin were under observation. The age of the patients was 22.4 ± 2.7 years. 32 patients were diagnosed with mild post-acne PIH, 25 patients – with moderate post-acne PIH. All patients used dermocosmetic products such as the triple effect serum (containing thiamidol, salicylic acid and lycochalcone A) and SPF30 fluid for problematic skin. Efficacy was evaluated with due account for mexametry findings, GSS, dermatology life quality index. Digital data were processed using standard medical statistical methods: calculation of the arithmetic mean value (X), square deviation (σ), Student’s t-test (t).Results. After 12 weeks the mexometric index decreased: 92.7 and 85.9% in mild and moderate post-acne PIH, respectively. The DLQ index reduced by 84.9 and 83.8% by the end of the treatment,Conclusions. The use of innovative dermocosmetic products containing salicylic acid and licochalcon A effectively reduces post-acne pigmentation. All patients noted good organoleptic properties: skin application comfort and excellent tolerability of the products.
