Even though melanin is commonly viewed as natural photoprotectant, the pigment
demonstrates residual photoreactivity, which under certain conditions could contribute to …

Photoreactivity of melanin has become a major focus of research due to the postulated
involvement of the pigment in UVA-induced melanoma. However, most of the hitherto …

Melanin is known to be photoreactive and photoprotective, but its function in skin in vivo is
still debated. Data is lacking of the effects of UVA irradiation on human skin melanosomes of …

To elucidate the mechanism of age-related changes in antioxidant and photoprotective
properties of human retinal pigment epithelium (RPE) melanosomes, the effect of in vitro …

When aging, melanin in human retinal pigment epithelium (RPE) undergoes oxidative
modifications, which increase its photoreactivity and reduce its antioxidant capacity …

Eumelanin is photoprotective while pheomelanin is phototoxic to pigmented tissues.
Ultraviolet A (UVA)‐induced tanning seems to result from the photooxidation of pre‐existing …

Aging may significantly modify antioxidant and photoprotective properties of melanin in
retinal pigment epithelium (RPE). Here, photoreactivity of melanosomes (MS), isolated from …

Melanin is usually considered a photoprotective pigment and antioxidant agent, but it is
unclear how melanosomes protect pigmented cells against oxidative stress induced by light …

Melanin, particularly eumelanin, is commonly viewed as an efficient antioxidant and
photoprotective pigment. Nonetheless, the ability of melanin to photogenerate reactive …

Although melanin is a photoprotective pigment, its elevated photochemical reactivity could
lead to various phototoxic processes. Photoreactivity of synthetic pheomelanin, derived from …
