How does UV radiation affect the skin?

The impact of UV radiation on the skin is significant and primarily associated with adverse effects. Exposure to UV radiation can cause immediate and long-term skin damage, including sunburn, premature aging, and alterations in skin texture and tone. The ultraviolet rays penetrate the skin and can cause direct DNA damage to skin cells, which increases the risk of developing skin cancers, such as melanoma and non-melanoma types.

Additionally, prolonged exposure to UV radiation can impair the skin's ability to repair itself and diminish the efficacy of the immune response, making it more susceptible to other skin issues, including infections and inflammatory diseases. Understanding this aspect of UV radiation is crucial in skincare and beauty practices, as protecting the skin from UV exposure through effective sun protection methods is necessary for maintaining skin health and preventing unwanted consequences.
