This is the process of extrinsic ageing that occurs from exposure to UV radiation. This is usually from sunlight, but can also occur in those who use solariums. At a cellular level there is damage to DNA and breakdown of structural proteins in the skin. This leads to wrinkles, pigmentation, dilated blood vessels and development of skin cancer.
This can occur in both adolescents and adults. There are often a variety of intrinsic & extrinsic factors that contribute. There are a range of topical, systemic and light based therapies that can significantly improve or even completely resolve this problem.
