UV radiation from the sun or artificial sources can harm your skin by causing sunburn, aging it faster, weakening your skin’s defenses, and even leading to skin cancer because it reaches deep into your skin.

Too much sun exposure can seriously harm your skin by damaging cells, aging it faster, weakening your skin’s defenses, and even leading to skin cancer.

UV light doesn’t just affect your skin — it might also change how your whole body works, possibly impacting things like inflammation, cancer, and even behavior.

Ultraviolet radiation exposure induces melanin production as a protective response, but this process simultaneously causes cumulative DNA damage in skin cells, leading to photoaging and increased risk of skin cancer.

Chronic ultraviolet radiation exposure is the primary etiological factor in the development of non-melanoma skin cancers, specifically basal cell carcinoma and squamous cell carcinoma, which frequently occur on sun-exposed facial regions and can result in significant structural disfigurement upon surgical excision.

UV light from the sun or tanning beds can irritate your skin and harm skin cells by changing how they work.
