How Does UV Exposure Affect the Skin at the Cellular Level?
UV exposure has a profound impact on the skin at the cellular level. The skin is composed of multiple layers, with the outermost being the epidermis. When UV radiation penetrates the skin, it can cause direct DNA damage in the epidermal cells. This damage can lead to mutations, which in turn can result in the formation of skin cancer such as melanoma, basal cell carcinoma, and squamous cell carcinoma.
