Severe acne is a chronic inflammatory skin disorder characterized by widespread inflammatory lesions including nodules, cysts and potential scarring. Here we perform the first genome-wide association study of severe acne in a Chinese Han population comprising 1,056 cases and 1,056 controls using the Illumina HumanOmniZhongHua-8 BeadChip. In an independent cohort of 1,860 cases and 3,660 controls of Chinese Han, we replicate 101 SNPs of which 3 showed consistent association. We identify two new susceptibility loci at 11p11.2 (DDB2, rs747650, P(combined)=4.41 × 10⁻⁹ and rs1060573, P(combined)=1.28 × 10⁻⁸) and 1q24.2 (SELL, rs7531806, P(combined)=1.20 × 10⁻⁸) that are involved in androgen metabolism, inflammation processes and scar formation in severe acne. These results point to new genetic susceptibility factors and suggest several new biological pathways related to severe acne.

Acne vulgaris (AV) has been associated with Cutibacterium acnes (C. acnes) colonization in sebaceous follicles. However, recent studies have revealed the role of skin microbiome dysbiosis in acne pathogenesis.

Isotretinoin (13-cis-retinoic acid) is a well-established systemic treatment for moderate to severe acne vulgaris, renowned for its ability to target multiple contributors to acne pathogenesis. However, its therapeutic potential extends beyond conventional acne management. This case report highlights its efficacy in treating recalcitrant pustular dermatosis, a condition that proved resistant to standard therapies and posed significant diagnostic challenges.

Background: Post-inflammatory hyperpigmentation (PIHP) predominantly affects patients with melanin-rich skin, significantly impacting them psychosocially due to more frequent and severe pigmentary changes. In this study, the efficacy of a novel depigmenting agent 2-mercaptonicotinoyl glycine (Melasyl) in a dermocosmetic (DC) serum formulation is assessed as a stand-alone treatment of PIHP without sunscreen.
Materials And Methods: Thirty-two Mauritian subjects aged 18-50 years of phototype IV-VI presenting mild acne (GEA2) and moderate to severe PIHP (PAHPI > 10) participated in this study.

Hidradenitis suppurativa (HS) is a chronic inflammatory cutaneous disease characterized by recurrent painful nodules, abscesses and sinus tract on the apocrine gland-bearing skin. The role of sex hormones in the pathogenesis as well as the use of hormonal treatment in the management of HS is still debated. We performed a retrospective cohort study including 183 patients to assess the influence of combined estrogen-progestin oral contraceptive (COC) in HS onset and disease severity.
