Photoaging — Where Most Skin Aging Comes From

Ultraviolet exposure drives an estimated 80% of visible facial aging; daily broad-spectrum sun protection is the most evidence-backed skin-longevity habit that exists.

How it works

UVA penetrates to the dermis and generates reactive oxygen species that activate collagen-degrading enzymes (MMPs) and damage elastin; UVB drives DNA damage and pigmentation. Randomized trials show daily sunscreen users age visibly less over years than occasional users. Antioxidants from within (vitamin C, carotenoids, polyphenols) and topically add a second layer of defense.

The practice

A broad-spectrum SPF 30+ every morning, a quarter-teaspoon for the face, reapplied outdoors; a hat and shade at peak hours; colorful plants on the plate for internal antioxidants; a vitamin-C serum in the morning under sunscreen for those who use actives.

The tradition

Ayurveda names sun as pitta-aggravating for skin — cooling oils, shade, and rose water are its counsel

Cautions

⚠ A changing, bleeding, or asymmetric mole is for a clinician promptly.
⚠ Sunscreen protects skin; vitamin D can be met with short exposure to arms and legs, food, or supplementation.
