How Sun Exposure Accelerates Skin Aging

Sun exposure is the leading cause of premature skin aging, a process known as photoaging. UVA and UVB rays damage the skin in different ways, but both contribute to visible aging.

UV radiation breaks down collagen and elastin, the proteins responsible for skin firmness and elasticity. Over time, this leads to wrinkles, sagging, enlarged pores, and uneven skin tone. Sun exposure also increases pigmentation, causing dark spots and discoloration.

Unlike natural aging, sun-related aging is largely preventable. Consistent daily sun protection significantly slows these changes and helps maintain youthful-looking skin.
