The human skin and eye melanin is commonly viewed as an efficient photoprotective agent.
To elucidate the molecular mechanism of the melanin-dependent photoprotection, we …

Melanins are considered to be natural photoprotectors in the melanocytes and keratinocytes
of the skin. These pigments have also been suggested to play an important role in protection …

Melanin, a ubiquitous, heterogeneous biological polymer composed of many different
monomers, contains a population of stationary, intrinsic semiquinone-like radicals …

Throughout the body, melanin is a homogenous biological polymer containing a population
of intrinsic, semiquinone-like radicals. Additional extrinsic free radicals are reversibly photo …

Melanin is the main pigment in animal skin. It is a heterogeneous polyphenolic molecule
with a generalized absorption in the UV− visible range synthesized in melanocytes, a kind of …

Human skin exhibited a stable electron spin resonance (ESR) signal before irradiation, only
if the samples were pigmented. The single almost symmetrical absorption peak with g …

Melanin is an irregular light-absorbing polymer containing indoles and other intermediate
products derived from the oxidation of tyrosine. Melanin is widely dispersed in the animal …

Melanins are a ubiquitous class of biological pigments, which play an important role in the
photoprotection of skin. Recent advances in the chemistry of melanins have demonstrated …

Melanins protect tissue by absorption and rapid nonradiative, nonreactive dissipation of
ultraviolet (UV) light. However, melanins also produce reactive oxygen species (ROS) upon …

Ultraviolet radiation (UVR) is one of the risk factors for skin cancer and the main inducer of
melanin pigmentation, the major protective mechanism of mammalian skin against radiation …
