Astaxanthin: Why could this super pigment dethrone vitamin C?
A natural skin shield, much more powerful than vitamin E or beta-carotene
Astaxanthin is one of those ingredients that is still relatively unknown to the general public. However, this natural orange-red pigment, extracted mainly from a freshwater microalgae (Haematococcus pluvialis), has unprecedented antioxidant properties. Its potential in skin protection, prevention of premature aging, and strengthening of the hydrolipidic barrier is now recognized.
What is Astaxanthin?
Astaxanthin is a xanthophyll, a pigment from the family of carotenoids, naturally present in certain algae, crustaceans, and fish such as salmon. Unlike beta-carotene, it does not convert into vitamin A in the body, which avoids any risk of toxicity associated with excess intake.
An Exceptional Cellular Antioxidant
Astaxanthin is capable of neutralizing free radicals. Thanks to its specific structure (affinity for both water and lipids), it positions itself across cell membranes, creating a stable and durable barrier against oxidative stress. It thus effectively protects skin cells from the harmful effects of UV rays, pollution, and stress.
Comparison of its antioxidant power to trap free radicals
Its action is:
. 65 times more potent than vitamin C
. 54 times higher than beta-carotene
. 14 times higher than vitamin E
Prevention of Skin Aging
The effects of aging are strongly linked to collagen degradation and lipid oxidation. Astaxanthin acts on several fronts:
- Collagen stimulation : by increasing inhibitors of metalloproteases (TIMP-1), it limits the destruction of dermal fibers.
- Membrane protection : it reduces lipid peroxidation, which is responsible for loss of elasticity and hydration.
- Preservation of cell structure : by strengthening membrane cohesion, it slows down the appearance of wrinkles.
Skin Hydration and Barrier Function
Topical application of astaxanthin significantly increases skin moisture content, particularly in people with dry or combination skin, with an improvement in barrier function.
Anti-Inflammatory Properties:
Astaxanthin helps reduce inflammation, decrease skin stress markers, and alleviate redness and reactions associated with certain skin conditions. This property is valuable for sensitive skin or skin prone to breakouts.
Possible Synergy with Other Assets
When combined with other compounds, astaxanthin enhances the effects:
- With vitamin E : improvement of sebum texture and prevention of blackheads
- With hyaluronic acid : improved skin hydration and suppleness
- With plant polyphenols : enhanced combined antioxidant action
Which Shape Should You Choose for Optimal Results?
It is essential to choose astaxanthin. naturally occurring, taken from Haematococcus pluvialis, preferably via a solvent-free CO₂ extraction process.
- Topical application : creams, serums, oils
- As a dietary supplement : recommended dose of 4 to 6 mg/day for the skin
To date, no significant side effects have been reported, either with oral or topical use.
