The Antioxidant That Will Preserve The Collagen Layers You Already Have

Have you ever heard of astaxanthin? As it turns out, this antioxidant might hold the key to youthful, glowing skin. Astaxanthin is a carotenoid with anti-inflammatory, photoprotective, and free radical scavenging effects, per a 2018 review published in Nutrients. It occurs naturally in certain bacteria, algae, and yeasts, but it can also be synthesized in labs. Researchers found that astaxanthin can reduce oxidative stress, which in turn may delay skin aging, boost immune function, and speed up wound healing. Moreover, this compound protects against premature aging and strengthens the skin barrier.

In clinical trials, men and women who used topical astaxanthin experienced improvements in skin texture, elasticity, and overall appearance, per the 2018 review in Nutrients. This naturally occurring compound may also lock in moisture and reduce wrinkles, leading to younger-looking skin. At the same time, it decreases excess sebum production and boosts collagen levels. As the scientists note, both topical and oral astaxanthin supplements appear to be effective.

This carotenoid may also protect your collagen layers against the harmful effects of ultraviolet radiation, according to 2014 research published in Marine Drugs. On top of that, it may help prevent skin cancer due to its antioxidant and anti-inflammatory effects. Perhaps unsurprisingly, astaxanthin has greater antioxidant power than beta-carotene, ascorbic acid, or vitamin C, per a 2007 study featured in Carotenoid Science.
