The main objectives of this symposium were to explore the effect of light on individuals with
hyperpigmentation disorders and acne, present the latest clinical research on the importance of photoprotection, and discuss the role of adapted photoprotection to improve patient adherence. Prof Passeron introduced the topic of hyperpigmentation by providing a brief background of pigmentary disorders and the mechanisms involved in ultraviolet (UV)B-induced pigmentation and the physiology of UVA pigmentation, and describing the latest findings from clinical studies that compared the effects of visible light and UVB on pigmentation and melasma. Dr Moyal presented the latest research on sun protection to prevent hyperpigmentation, focussing on the need for products to contain very high-level and well-balanced protection against UVA and UVB light, and discussed adherence, as well as how formulations can be adapted to meet patient needs by skin type, texture preference, and climatic requirements. Dr Moyal also presented the latest research on post-inflammatory hyperpigmentation (PIH) as a long-lasting sequela of acne, photoprotection to prevent drug-induced phototoxicity, and whether adapted dermocosmetics and photoprotection can be used to prevent acne outbreaks. Prof Trautinger provided an overview of the epidemiology, physiology, and interaction with light and presented studies regarding the effect that sunlight has on acne severity. Prof Trautinger also discussed why photoprotection is important for patients with acne, focussing on the phototoxic side effects of conventional acne treatment.
