learn more about the biopolymer powering our products

what is chitosan?

Chitosan is a biopolymer, a natural substance extracted from chitin. Under mild acidic conditions, it becomes positively charged, rendering it bio-adhesive. This allows it to adhere to the skin as a protective film, conferring many important biological properties, including moisture control, skin renewal and antioxidant action.

film-forming

Adheres to the skin as a biocompatible, protective film, helping to lock in moisture, support the natural repair process and nourish the skin.

barrier support

Supports the skin barrier and replenishes moisture, contributing to firmness and elasticity for an overall youthful appearance.

antioxidant action

Provides antioxidant fortification to protect the skin from the effects of environmental, oxidative and UV damage.

BIOCOMPATIBLE

Ideal for daily skin treatment. Suitable for all skin types, including sensitive skin or skin prone to conditions like acne, eczema, psoriasis or rosacea.

core chitosan facts

where does chitosan come from?

Chitosan is functional polysaccharide extracted from the chitin polymer. After purification, it is extracted using a special process called deacetylation.

what is chitin?

Chitin is the second-most abundant natural polymer on Earth, after cellulose. It is found in the shells of crustaceans, like crabs, shrimps, and lobsters, and in some fungi, like mushrooms.

what does chitosan do?

Chitosan is a rare, positively-charged biopolymer that adheres to the skin, covering it in a thin, protective film that locks in moisture and keeps out aggressors.

Is chitosan safe?

ChitoCare chitosan is certified natural and safe. It contains amino sugars, making it biocompatible. It breaks down easily in the environment, making it an eco-friendly choice for skincare.

chitosan deep dive

Our chitosan comes from the Pandalus Borealis shrimp, sustainably sourced from the clean, cold waters around Iceland. Our chitosan is manufactured in house according to strict quality regulations and all our products undergo clinical testing to ensure safety and efficacy.

CHITOSAN FUNCTIONS

Chitosan is used in all of our products, thanks to its many unique properties. Depending on the product group, molecular weight and concentration, it confers different benefits for skin, hair, nails, gut health and overall wellness. Thus, the chitosan in our topical skincare formulas functions a bit differently to the chitosan in our medical devices. And, because chitosan is also a natural fibre, it provides a different set of wellness benefits when ingested as a dietary supplement. Below is a basic breakdown.
