Why Sun Exposure Damages Skin — And How to Defend It

Of all the factors that affect skin health, unprotected sun exposure causes the most damage over time — and it's also the most preventable.

Why sun exposure harms the skin

UV rays penetrate the skin and trigger excess melanin production as a defense response — this is what causes tanning, but also what causes dark spots, uneven tone and melasma to worsen. Over years, UV exposure also breaks down collagen, leading to fine lines and premature aging. For South Asian skin in particular, sun exposure tends to trigger more visible, longer-lasting pigmentation than it does on lower-melanin skin.

Why daily protection matters more than treatment

Most people only think about sunscreen at the beach, but daily unprotected exposure — walking outside, driving, sitting near a window — adds up over years and is responsible for the majority of visible sun damage. No brightening or anti-aging product can outpace ongoing, unprotected UV exposure.
