  • COMPLEX PROTECT 3C: an exclusive and highly tolerated preservative system.
  • F. P. D. PATENT: thermal spring water encapsulation system to ensure ultimate hydration.
  • 3P PERFECTING COMPLEX: active ingredient system that works on the 3 factors of perfect skin perception.
  • CICATHERMALE®: a system combining soothing and revitalizing Jonzac thermal spring water with the restorative virtues of organic Centella asiatica.


Protect 3C Complex

This is a unique combination of 3 preservatives that are recognized both for their level of safety and for their efficiency.  This combination was tested for several months on volunteers with skins that are particularly sensitive and reactive to regular preservatives. The Protect 3C Complex was demonstrated to be extremely well tolerated by the skin, very safe and effective as a preservative.

The F. P. D. Patent

Laboratoire Léa Nature has patented the F.P.D. process that consists in encapsulating thermal spring water in a phospholipid lamellar gel, which leaves a film on the surface of the skin, ensuring deeper penetration into the layers and preserving moisture so that it is progressively released into the tissues.

The 3P Perfection Complex

This innovative system is based on powerful natural ingredients that act on the 3 perception points for perfect skin:  skin tone, complexion, skin texture.  An extract obtained from brown algae serves to even out and brighten skin tone thanks to brown algae extract.  Zinc and hamamelis floral water improve skin texture thanks to their pore-tightening and purifying virtues.

The Cicathermale® patent

Soothing and revitalizing Jonzac thermal spring water is combined with organic centella asiatica, a plant renowned for millennia in Ayurvedic medicine for its restorative virtues. This plant extract contains 4 main active components (asiaticoside, madecassoside, asiatic and madecassic acids), that are known to stimulate collagen and elastin synthesis and regulate inflammation.
