Astaxanthin (Skin)
A potent carotenoid antioxidant that protects skin from UV damage and aging.
Also known as: Astaxanthin • AstaReal • BioAstin
Overview
Astaxanthin is a keto-carotenoid pigment found in microalgae, yeast, salmon, and shrimp. It is one of the most powerful antioxidants known, with potent anti-inflammatory and UV-protective properties. For the skin, astaxanthin helps to neutralize free radicals generated by sun exposure, reducing oxidative stress that leads to wrinkles, fine lines, and hyperpigmentation. It improves skin moisture, elasticity, and smoothness.
Key Benefits

Astaxanthin accumulates in the skin, where it provides protection against UVA-induced oxidative stress.
Improves Skin Elasticity and Moisture
Studies show it can improve skin texture, elasticity, and hydration levels, reducing the appearance of fine lines.
Reduces Hyperpigmentation
It can inhibit melanin production, helping to lighten age spots and hyperpigmentation.
