This review links core molecular mechanisms, including ULK1 signalling, Beclin-1/VPS34 nucleation, LC3B lipidation and selective mitophagy, to dysregulation in psoriasis, atopic dermatitis, vitiligo, melanoma, non-melanoma cancers, infections, wound repair and ageing.

In keratinocytes it sculpts the cornified envelope; in melanocytes it balances pigment synthesis and oxidative stress; in immune and appendageal cells it fine-tunes defence, repair and hair-follicle cycling. When this choreography falters, skin disorders emerge. This review journeys from basic mechanisms (ULK1 signalling, Beclin-1/VPS34 nucleation, LC3B lipidation, selective mitophagy) to their fingerprints in health and disease. We dissect how autophagy malfunctions drive psoriasis hyper-proliferation, atopic-dermatitis barrier leakiness, vitiligo depigmentation and the metabolic rewiring of melanoma. Non-melanoma cancers, infectious dermatoses, wound repair, ageing and photo-damage are mapped onto the same autophagic atlas. Therapeutically, the pathway is a double-edged sword. mTOR or caloric-restriction mimetics jump-start a protective flux; chloroquine derivativesand ULK1 blockers clip tumour survival circuits; cannabinoids, photodynamic therapy and immune-checkpoint combinations exploit context-specific toggling between induction and brake. Emerging biomarkers (LC3B-II, p62, AMBRA1) promise patient-stratified interventions. By weaving together molecular detail, pre-clinical insight and clinical translation, we show why autophagy is no longer a backstage process but a star player in dermatology – and how targeting its switches could reshape future treatment algorithms.  \nKeywords Autophagy, Mitophagy, Skin disorders, Dermatological disease, Skin homeostasis, Immunodermatology  \n†Luca D’Ambrosio, Maria Elisabetta Greco, Elisa Dietrich, and Leonardo Schirone equal contribution.  \n*Correspondence: Leonardo Schirone [leonardo.schirone@unier.it](leonardo.schirone@unier.it)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
