Astaxanthin: What is it?

Theastaxanthin is a natural pigment of reddish-orange color. It belongs to the family of carotenoids, specifically xanthophylls. It is ubiquitous in nature, especially in the marine environment. Responsible for the coloration of certain seafood, it is found in crustaceans, such as krill, lobsters, and shrimp. It is also present in certain fish, including mackerel, trout, cod, and salmon. However, the main source of natural astaxanthin is a freshwater microalgae called Haematococcus pluvialis.

Astaxanthin is a favored active ingredient in topical treatments due to its antioxidant action. It is capable of trapping free radicals and protecting cells from oxidative stress. It has a proven action against singlet oxygen. The latter is a free radical, the source of the harmful effects of UV rays on the skin. By trapping it along with other free radicals, astaxanthin protects the skin from premature aging.

Furthermore, astaxanthin is capable of stimulating the production of collagen, a protein responsible for skin elasticity, by increasing the level of TIMP-1, an inhibitor of matrix metalloproteinases. As a result, the skin is protected from wrinkles and fine lines, regains its elasticity, and its ability to regenerate the tissues of the epidermis. It is used in topical treatments to protect the skin from oxidation and prevent skin aging.

Astaxanthin can also be used to reduce inflammation of the scalp or skin during skin diseases. It decreases the levels of matrix metalloproteinases (MMP) and pro-inflammatory cytokines by inhibiting the activity of IκB kinase.

Which astaxanthin should you choose to benefit from its skin advantages?

Astaxanthin is a natural pigment that can be obtained through diet. However, to ensure you reap its multiple benefits for the skin, it is recommended to use it as a topical treatment or dietary supplement. Before choosing the galenic form of astaxanthin, it is important to ensure:

  • Its origin.

    The astaxanthin used in skincare products should be of natural origin. In order to benefit from a treatment without side effects, astaxanthin derived from the micro-algaeHaematococcus pluvialisis recommended. Indeed, a study published in 2013 showed that the antioxidant activity of natural astaxanthin was 14 times higher than that of synthetic astaxanthin.

  • Its manufacturing process.

    We advise you to favor astaxanthin extracted through the supercritical CO2 extraction process. This method allows us to obtain an active ingredient without the use of nonpolar solvents, keeping it as natural as possible.

  • Its dosage.

    In its dietary supplement form, clinical studies have revealed that astaxanthin improves the texture, appearance, and moisture content of the skin. To benefit from its antioxidant properties, it is recommended to start with a dose of 4 mg per day. Its proportion in a skincare product is calculated to not cause any form of allergy. To date, there are no proven adverse effects from overdosing on topical astaxanthin. However, it is advised to discontinue use in case of allergy, irritation, or inflammation.

In what form should astaxanthin be used?

Belonging to the large family of carotenoids, theastaxanthin possesses unparalleled antioxidant virtues. It is a beneficial active ingredient for all skin types, even sensitive ones. It can be used in several ways, either orally or topically applied.

How to use astaxanthin in topical application?

Astaxanthin is recognized for its ability to trap free radicals and protect cells from oxidative stress, with the aim of shielding the skin from photoaging and restoring its radiance. Serum, mask, cream... it can be incorporated into the formulation of numerous cosmetics to take advantage of its benefits when applied topically.

At Typology, we have chosen to incorporateastaxanthin natural (INCI: Haematococcus Pluvialis Extract) into our antioxidant face cream. It acts as a cellular shield that fights against the phenomenon of premature skin aging. With thekale extract (INCI: Brassica Oleracea Acephala Leaf Extract) and theginseng extract (INCI: Panax Ginseng Root Extract), it reduces the effects of oxidative stress and hydrates the skin for a luminous complexion.

How to use astaxanthin orally?

In its dietary supplement form, clinical studies have revealed that astaxanthin has improved skin texture, appearance, and moisture content. Moreover, oral intake of astaxanthin is beneficial as it enhances cognitive functions, promotes recovery after exercise, prevents eye fatigue, and supports the immune system. To reap its benefits, it is recommended to start with a dose of 4 mg per day.
