Benefits: All skin typologies; All hair types.



  • Hair Conditioner: Preventing the deterioration of the hair fiber by constructing a protective polysaccharide matrix on the surface of the hair;

  • Filmogenic Protective Layer: Minimizing the penetration into the skin of pro-oxidant stress factors (such as atmospheric and domestic pollution, smoking, etc.) associated with premature aging, thereby limiting the risk of biological damage by forming a non-occlusive adherent biofilm, or "second skin" effect, on the surface of the epidermis, while providing a soft and comfortable sensation;

  • Moisturizer: Keeping the skin hydrated and providing long-lasting hydration to the skin by creating a protective physical film on the surface of the epidermis, minimizing transepidermal water loss.


  • Facial Care (facial serums, facial creams, facial masks, sun care products);

  • Body Care (hand creams);

  • Hair Care (shampoos, hair serums);

  • Makeups (foundations, primer bases).
