Astaxanthin for Sun Damage (Photoaging)

A powerful pink antioxidant from algae. Defends against UV and environmental damage.

Why it works for Sun Damage (Photoaging)

A strong antioxidant (a red pigment from algae) that neutralizes UV-damaging molecules even better than beta-carotene or vitamin E in lab tests. In a 16-week study that treated one side of the face at 0.078 percent (Tominaga et al., 2012), wrinkles got shallower and skin got springier. It also boosts the skin's own antioxidant defenses. Researchers are still studying it, including combining a cream with an oral supplement. The evidence is early but the way it works makes sense.

How Astaxanthin works

Carotenoid antioxidant from algae that quenches singlet oxygen far more efficiently than vitamin E.
