Sun Tanning

It is prudent to limit exposure of skin to sunlight  and UV radiation from tanning beds. According to the National Toxicology Program Report on Carcinogens from the Department of Health and Human Services, broad-spectrum UV radiation is a carcinogen thought to contribute to most of the estimated 1.5 million skin cancers and the 8,000 deaths due to metastatic melanoma that occur annually in the United States.  Lifetime cumulative UV damage to skin is also largely responsible for some age-associated dryness and other cosmetic changes.

Facial Nevus

Giant congenital pigmented nevi of the face are rare but of major consequence. Complete early excision of these lesions is recommended not only because of the cosmetic deformity they impose but also because of their life threatening potential for malignant transformation.  Although an accurate incidence of malignant transformation has not been determined, the risk of malignancy in congenital giant facial nevi must be considered (adapted from Giant congenital pigmented nevus of face –link)

Stretch Marks

Stretch marks or striae, are a form of scarring on the skin with an off-color hue. They are caused by tearing of the dermis, which over time may diminish, but will not disappear completely.

Stretch marks are often the result of the rapid stretching of the skin associated with rapid growth or rapid weight changes. Stretch marks may also be influenced by hormonal changes associated with puberty, pregnancy, bodybuilding, hormone replacement therapy, etc. (adapted from Wikipedia)
