How Tanning Works (and Why It’s Risky)

Tanning is your skin’s defense mechanism against UV radiation, not a beauty function.
UV-B light triggers melanocytes to produce extra melanin for protection.
The resulting darkened pigment layer absorbs radiation to protect deeper tissues.
A tan actually indicates that DNA damage has already occurred.
Repeated UV exposure breaks collagen and leads to early wrinkles.
Indoor tanning beds emit concentrated UV — often more dangerous than sunlight.
Fake tans only color the outer layer and don’t offer any UV protection.
Genetics decide how well or poorly your skin tans.
Every sunburn raises long-term skin cancer risk.
Healthy glow ≠ UV tan — it’s better achieved through hydration and diet.
