Collagen is imperative in maintaining healthy, youthful skin. As we age, the collagen in our skin slowly breaks down and we begin to wrinkle. Other factors, such as smoking, sun exposure, and free radicals in the air can contribute to the breakdown of collagen.

A recent study from The University of Texas MD Anderson Cancer Center has reversed previous findings that early life exposure to ultraviolet A (UVA) light causes melanoma. According to the findings, UVA exposure is unlikely to have contributed to the rise in occurrences of melanoma over the past 30 years because the fish model is the only animal model to show a connection between UVA exposure at a young age and melanoma development.
