Abstract

Melasma is a hyper-pigmentary disorder with photoaging features. Since the manifestations appear on specific face areas, rich in sebaceous glands, we explored their possible role in the onset. The gene and protein expression of inflammatory and pro-melanogenic factors from the SZ95 sebaceous gland cell line exposed to single or repetitive UVA doses (2 to 8 J/cm2), as triggering stimulus able to reach the dermis and skin appendages, were evaluated. UVA up-modulated the long-lasting production of α-MSH, EDN1, b-FGF, SCF, inflammatory cytokines, and lipid-derived mediators, through the p53 and PPARγ activation, since the interfering significantly reduced the production.
