摘要

Hyperpigmentation disorders affect a large proportion of the population, significantly impacting their quality of life and carrying considerable social stigma. This growing global concern results in a strong demand for effective treatments. A rich body of literature proposes numerous active ingredients to solve hyperpigmentation concerns. At the same time, the complex regulation of skin pigmentation is much better understood with increased knowledge on the physiopathology of pigmentary disorders, beyond the sole melanogenesis, including the whole tissue environment of melanocytes. The abundance of mechanistic in vitro and in vivo scientific data makes it challenging for non-expert clinicians to identify the optimal care for patients. The aim of this review is to propose state-of-the-art of topical solutions with actives that have demonstrated conclusive clinical efficacy. It analyzes the different mechanisms involved, including the melanogenesis pathway and others addressing the melanocyte microenvironment. This review first examines the prevention of pigmentary disorders and the importance of a broad-spectrum photoprotection including the whole UV spectrum but also visible light in managing hyperpigmentation. The use of antioxidants to combat oxidative stress and complement photoprotection is also discussed. The following section reviews actives targeting the modulation of melanogenesis. It examines tyrosinase inhibitors, which are still widely used to manage hyperpigmentation problems, as well as new compounds targeting downstream pathways. Other clinically effective interventions include the normalization of epidermal homeostasis and the active restoration of the dermal fibroblastic microenvironment, together with anti-inflammatory agents and those aimed at reducing vascularization impact. Finally, this review highlights the value of combined approaches which have been shown to improve clinical efficacy. This suggests that future research should focus on well-tolerated, multifaceted therapies to effectively treat melanin hyperpigmentary disorders.
