Photoexcitation of endogenous photosensitizers (ePS) in the human skin by sunlight
culminates with the formation of electronic excited states, such as triplet excited states …

Human skin is repeatedly exposed to UVR that influences the function and survival of many
cell types and is regarded as the main causative factor in the induction of skin cancer. It has …

In living cells, melanin pigment is formed within melanosomes, which not only protect the
cells from autodestruction, but also serve as second messenger organelles regulating …

The term barrier function as applied to human skin often connotes the physical properties of
this organ that provides protection from its surrounding environment. This term does not …

Purpose Isolated melanosomes are known to have antioxidant properties but whether the
granules perform an antioxidant function within cells is unclear. The aim of this study was to …

This study uses various microscopy techniques to monitor the effects and extent of damage
caused by UV radiation on the microstructure and physical nature of hair fibers. Field …

We present an in vivo study of the optical properties of melanin present in melanocytic nevi
of human subjects with Fitzpatrick skin type III (Caucasian descent) using optical …

The effects of sun exposure on the skin and specifically those related to pigmentation
disorders are well known. It has recently been shown that blue light leads to the induction of …

The photobiology of mouse melanocyte lines with different pigment genotypes was studied
by measuring colony‐forming ability after irradiation. The cell lines were wild‐type black …

Ultraviolet radiation (UVR) has been implicated as a major environmental factor in the
pathogenesis of photoaging and skin cancers including melanoma. Hypermelanosis …
