Astaxanthin is a red-orange carotenoid, primarily produced by the microalga Haematococcus pluvialis. It is documented as one of the most studied antioxidants in cosmetics, with a particularly notable antioxidant profile in the available scientific data.
Its molecular structure allows it, according to these data, to integrate into cell membranes, a property associated with documented antioxidant protection. Astaxanthin is linked to the neutralization of several reactive species such as singlet oxygen and hydroxyl radicals, recognized for contributing to protection against oxidative stress and its factors related to the visible signs of aging: appearance of wrinkles, dull complexion.
Clinical studies report, after astaxanthin supplementation, a visible improvement in the appearance of skin suppleness, hydration comfort, and texture. It is also documented for its association with protection against UV-induced oxidative stress and the visible reduction of pigment irregularities.
In summary, an active ingredient associated with a documented antioxidant profile and support for skin appearance.
