Chitosan – The regenerating marine active ingredient at the heart of R6

A biomimetic active ingredient for the benefit of the skin

Derived from marine biotechnology, chitosan is a natural polysaccharide extracted from chitin, a molecule found in the shells of crustaceans.
Biocompatible, biodegradable and environmentally friendly, it is now attracting dermatology and advanced cosmetics for its multiple benefits on the skin.

At Medspa Laboratories, it occupies a central place in the formulation of the R6 – Soothing Peel-Off Mask with Chitosan, where it acts in perfect synergy with alginate and diatomaceous earth to restore skin comfort and stimulate cell regeneration.

A smart protective film

Chitosan is distinguished by its film-forming power: it creates an invisible and breathable veil on the surface of the skin, comparable to a second skin.
This biomimetic film acts as a natural barrier against water loss and external aggressions (pollution, UV, oxidative stress), while preserving the balance of the skin microbiome.

The skin is better hydrated, more supple, and immediately soothed — a true protective envelope that promotes epidermal recovery.

Deep hydration and soothing

Thanks to its hygroscopic structure, chitosan retains water in the upper layers of the epidermis, maintaining an optimal hydration level.
But it does more than just trap moisture: it soothes redness and burning sensations by regulating the skin's inflammatory responses.

It is the ideal active ingredient for sensitive, irritated or weakened skin, which seeks long-lasting hydration without a greasy or occlusive effect.

A regeneration accelerator

Beyond hydration, chitosan acts as a catalyst for skin repair.
Studies have demonstrated its ability to stimulate the proliferation of fibroblasts — the cells responsible for the production of collagen and elastin.
Result: improved tissue cohesion, more resilient and visibly regenerated skin.

In R6, this effect is enhanced by the synergy of marine minerals, for complete skin repair and an immediate feeling of comfort.

A biotechnological innovation by Medspa

By incorporating chitosan into a peel-off formula, Medspa has been able to exploit its full biomimetic potential.
The R6 – Soothing Peel-Off Mask with Chitosan offers a unique sensory experience: fresh and sculpting texture, soothing contact, visible results from the first application.

The perfect alliance between marine biotechnology and dermatological science.

Key Benefits of Chitosan

• Provides lasting hydration and limits water loss

• Soothes irritations and calms redness

• Protects the skin barrier against external aggressions

• Promotes tissue repair and regeneration

• Strengthens the skin's suppleness and elasticity

Medspa's commitment

Each Medspa formula is the result of demanding research, combining dermatological safety, proven effectiveness and refined sensory experience.
Chitosan, at the heart of R6, embodies this philosophy:

Repair, soothe and hydrate — with the precision of science and the gentleness of the sea.
