Unprotected outdoor activity raises skin cancer risk. This is a major sun exposure risk. Skin tumors are many. Melanoma or basal cell carcinoma could occur.
Sun exposure can also accelerate aging. If you don't protect yourself outside, you may get lines, wrinkles, blemishes, and spots that make you look older.
Sunburns are a common result of not applying sunscreen. Sunburns vary in severity. Blisters can result from severe sunburns. Sunburns can cause long-term health issues.
Without sunscreen, you risk skin darkening. Sun damage causes dark patches, often known as age spots. It boosts melanin production.
Repeated sun exposure can also make scars darker and more apparent. Blistering and peeling can worsen and scar if not treated.
UVA radiation inhibits antigen presentation, increases immunosuppressive cytokines, and produces immune-suppressing regulatory cells.
Sun exposure can dry up your skin, and when UV rays interact with skin cells, they can affect tissue growth and appearance.
