What Histological Changes Occur Due to UV Exposure?
Prolonged exposure to UV radiation leads to various histological changes in the skin. In the epidermis, there is an increase in the number of melanocytes as a protective response, causing tanning. The dermis shows a breakdown of collagen fibers and accumulation of abnormal elastin, leading to wrinkles and loss of skin elasticity. UV exposure can also cause mutations in the DNA of skin cells, leading to carcinogenesis.
