It has always been recognized that overexposure to sun rays or ultraviolet radiation would significantly damage one’s skin. The penetration of ultraviolet rays into the skin can damage collagen, a protein known to hold the skin together in a smooth and firm way (Vincent 37). It causes melanoma, a rare but most deadly skin cancer type. Testament to its deadly nature is the fact that it accounts for over 80% of all skin cancer deaths. Melanoma occurs when melanocytes become mutated and affects various parts of the skin including scalp, nail beds, anus, eyes, and soles of the feet.

Ultraviolet radiation of the sun is known to attack the pigmentation cells or melanocytes. The cells react by increasing the melanin production as well as sending melanosomes to the surface of the skin (Vincent 36). While these melanosomes filter out the sun rays, they also destroy the pigmentation cells’ DNA thereby resulting to melanoma, age spots and freckles. In essence, overproduction or underproduction of skin pigmentation or melanin would result in skin problems.

Melanocytes play a unique role as far as determining the skin and hair coloration is concerned. However, in protecting the skin against harmful sun radiation, it may produce too many melanosomes, which could destroy the pigmentation cells thereby resulting in skin cancer, as well as other skin conditions (Vermon
