Age-related skin changes (wrinkles, elasticity)
Not recommended
Astaxanthin is a natural carotenoid antioxidant from algae, added to supplements and creams and marketed for wrinkles and skin elasticity. Solid benefit for this use hasn't been shown, and the evidence for skin rejuvenation is lacking. For age-related skin changes, the approaches with real support are sun protection, retinoids, and regular moisturizing.
