The Proven Power of Chitosan

A nature-derived biopolymer backed by science

Chitosan is a natural biopolymer derived from chitin — the second most abundant biopolymer on Earth — found in fungi, algae, and the protective exoskeletons of insects and crustaceans. Extensively studied for decades, it’s recognized in the scientific and medical communities for its wide-ranging benefits in skin health, wound care, and barrier support. Below are just a few of the clinically documented properties that make chitosan such a powerful active ingredient.

The clinically supported benefits of chitosan include:

Barrier Repair & Protection

Chitosan forms a breathable, semi-occlusive film that protects the skin while allowing air and moisture exchange. This barrier supports healing, reduces transepidermal water loss (TEWL), and defends against environmental irritants.

Supports a Clean, Balanced Skin Surface

Chitosan forms a protective film on the skin that discourages the growth and adhesion of harmful microbes. This creates an environment that is less favorable for bacteria and fungi, supporting clearer, calmer skin—especially in areas prone to breakouts, irritation, or barrier compromise.

Enhances Delivery of Active Ingredients

Chitosan can form nano- or micro-particles that improve the penetration of actives into deeper skin layers making it an excellent tool for delivering vitamins, peptides, or antioxidants more effectively.

Hydration & Moisture Retention

Acting like a humectant, chitosan helps draw and hold moisture in the skin. It works synergistically with your body’s natural hydration processes without clogging pores or leaving residue.

Wound Healing & Tissue Regeneration

In peer-reviewed studies, chitosan has been shown to accelerate wound healing by promoting cell proliferation, tissue regeneration, and collagen production. It’s been used in medical settings for burns, cuts, and post-surgical recovery in FDA-cleared formulations for wound care.

Anti-Inflammatory Effects

Research suggests chitosan can help modulate the skin’s inflammatory response, reducing redness, irritation, and sensitivity from environmental stressors or harsh treatments. Its gentle nature makes it ideal for sensitive and reactive skin types including beneficial for eczema, rosacea, or psoriasis-prone skin.

Biocompatible & Biodegradable

Chitosan is both biocompatible (well tolerated by human tissue) and biodegradable, making it safe for sensitive skin and eco-friendly by design. It’s even been used in surgical applications and tissue engineering.

A Natural Active Ingredient with a High-Tech Resume

From space research aboard the MIR space station to clinical wound care settings, chitosan has quietly earned its place as one of the most versatile and effective bioactive ingredients available today.
