title: Induction of UVA pigmentation in pressure areas by hydrogen peroxide.
abstract: Heavy external pressure, caused by the weight of the body when lying on a hard transparent surface during UVA irradiation, prevents pigmentation in pressure exposed skin areas. After percutaneous H2O2 administration a delayed pigmentation appeared on the pressure sites. This finding provides evidence for the role of oxygen in delayed pigmentation by UVA.
