A Protective Cocoon for Sensitive Skins.

Skin hypersensitivity is a global problem. Many consumers suffer from related conditions and dream of feeling comfortable in their own skin again.

ALGAENIA®, concentrate of peptides extracted from microalgae, is a real cocoon for the skin. ALGAENIA® gives skin the power to protect itself against the harsh conditions of our environment!

With ALGAENIA® it is possible to target typical skin issues.

Demonstrated effects:

  • Protection against sensitisers and allergens

  • Anti-inflammatory effect

  • Soothing of stressed-out skin

  • Barrier reinforcement

  • Deep hydration

Two clinical studies demonstrate the properties of Algaenia®: 

  • On normal skin, used at 3% as a preventive measure: limits inflammation after induction of erythema (chemical stress).
  • On sensitive skin, used at 3%: rebalances various markers of inflammation such as cytokines or hydration markers such as NMF and involucrine.


A sustainable and innovative culture process

ALGAENIA® is made of a microalga cultivated in a reasoned and sustainable way, in which the environment and the biodiversity remains preserved. The natural high-tech active ingredient is a concentrate of peptides obtained from Chlamydomonas acidophila microalgae by a bio-enzymatic process developed and patented by Laboratoires Expanscience.

Examples of our responsible actions:

  • Reasonable and sustainable production
  • Biodiversity preservation
  • Partnership with a local company - Microphyt
