PUVA is an acronym. The P stands for psoralen, the U for ultra, the V for violet, and the A for that portion of the solar spectrum between 320 and 400 nanometers in wavelength. Psoralens are chemicals found in certain plants that have the ability to absorb ultraviolet light in the UVA portion of the […]
Pigmentation refers to the coloring of the skin. Melanin is the pigment responsible for skin color. Melanin acts as a protective barrier against the harmful effects of ultraviolet (UV) rays. Melanin offers antioxidant activity by scavenging for reactive oxygen species produced via UV. What happens if you don’t have enough melanin? Melanin in excess – Hyperpigmentation […]
Melanin is a skin pigment that not only gives colour to the skin also protects skin cells from UVB radiation damage, reducing the risk of folate depletion, dermal degradation and increased risk of malignant melanoma, a cancer of melanocytes (melanin cells) and wholly creates a protective layer from the Sun/UV rays. A condition where melanin is scarcely found in skin […]
The colour of human skin depends mainly on pigments present in the skin and blood flow of the skin. The most important pigment is Melanin which is synthesized by melanocyte cells. The melanosome of melanocyte chiefly synthesize the melanin. Melanogenesis Melanin synthesis is influenced by Constitutional skin colour U-V radiation Hormone Vitiligo Vitiligo is a […]
