Cutaneous malignant melanoma (CMM) is one of the most rapidly increasing cancers in the
western world (Bowden, 2004). Frequency of its occurrence is closely associated with skin …

In recent years, interest is growing in the biological cutaneous effects of high‐energy visible
light (400–450 nm). In the present study, we explored the impact of blue light (BL) on the …

Melanins, pigments of photoprotection and camouflage, are very photoreactive and can both
absorb and emit active oxygen species. Nevertheless, black skinned individuals rarely …

Melanin is both photosensitizer and photoprotector. Skin cancer rates decrease with
increasing constitutive pigmentation, yet the pigment has been shown to be photoreactive …

Melanin is a free‐radical scavenger, antioxidant, and broadband absorber of ultraviolet (UV)
radiation which protects the skin from environmental carcinogenesis. However, melanin …

Highly pigmented, dark skin is more resistant to the harmful effects of solar ultraviolet
radiation than light-colored human skin. The extent to which tanning protects skin from …

Ultraviolet (UV) irradiation is a major source of environmental damage to skin. Melanin
pigmentation protects against this damage by absorbing UV photons and UV-generated free …

The question of whether melanins are photoprotecting and/or photosensitizing in human
skin cells continues to be debated. To evaluate the role of melanin upon UVA irradiation …

Exposure to solar UV radiation is the main cause for all forms of skin cancers, including
melanoma. UVB photons (290–320 nm wavelength) represent the most energetic and …

Melanins have been associated with the development of melanoma and its resistance to
photodynamic therapy (PDT). Singlet molecular oxygen (1O2), which is produced by …
