Astaxanthin is a versatile antioxidant with benefits for skin protection and anti-aging. The natural pigment from the world of algae is becoming increasingly popular in natural cosmetics as it binds free radicals and naturally nourishes the skin. Learn why this natural all-rounder should no longer be missing from your cosmetic routine!

What is Astaxanthin?

Astaxanthin is a red pigment that belongs to the carotenoid group. It is produced by microalgae and is responsible for the red color of salmon, crabs, and flamingos, which absorb it through their diet. This natural substance is considered one of the strongest antioxidants nature has to offer. Due to its properties, Astaxanthin is an active ingredient that can be used both externally in cosmetics and internally, either through certain foods or as a dietary supplement.

How does Astaxanthin work on the skin?

Astaxanthin is currently conquering the world of cosmetics and is the subject of numerous studies, particularly in the field of skin health and anti-aging. Studies show that the antioxidant properties of the red active ingredient are very high. At the same time, it supports the natural regeneration of the skin, making it firmer and more elastic. Thanks to its skin-soothing properties, Astaxanthin can also have a calming effect on irritated or sensitive skin.

What are Free Radicals and Antioxidants?

Free radicals are molecules that are produced during metabolic processes in our body, as well as by many other factors such as UV radiation, smoking, or stress. These highly reactive molecules lack an electron, so they 'try' to snatch an electron from other molecules, causing damage. Antioxidants are substances whose molecules can donate an electron. They stabilize free radicals and interrupt their harmful effects. For example, they help minimize skin aging and cell damage. Since Astaxanthin is one of the strongest antioxidants, it protects against free radicals caused by UV radiation, environmental pollution, and stress, preserving the skin from oxidative damage.

Are there side effects when applied to the skin?

Astaxanthin is considered a safe and well-tolerated ingredient in cosmetic products where allergic reactions are rare. We recommend testing the products in the crook of your arm or on the inside of your forearm before widespread use. The skin here is very sensitive and quickly shows whether a care product causes a reaction or is well tolerated.
