What is astaxanthin?

Astaxanthin is a powerful antioxidant that is mainly obtained from microalgae. Known for its intense red color, it is often used in aquaculture to color salmon, shrimp and other seafood. It has become increasingly important in skin care due to its antioxidant properties, which are stronger than vitamin E and beta-carotene.

Benefits of astaxanthin for the skin

Protection from UV rays

Improvement of skin elasticity

It supports skin elasticity and promotes a healthy, radiant complexion.

Possible side effects

Astaxanthin is generally well tolerated and is safe for most skin types. Allergic reactions are rare, but as with any new skin care product, a patch test should be carried out before use.

In creams and serums

How not to use astaxanthin

  • Do not combine with irritating ingredients: The combination with products containing irritating substances may increase skin sensitivity.
  • Avoid overdosing: Excessive use can lead to saturation of the skin’s antioxidant capacity and is not necessarily more effective.
