Chitosan, Carboxymethyl type Extracted from shellfish and crab shells through a process that makes it easily soluble in water. Can be used for many things in cosmetics.

Various research About the use of Chitosan in cosmetic products

1. Moisturizing Properties: Carboxymethyl chitosan has been studied for its moisturizing effects in cosmetics, which can help maintain skin hydration and improve skin feel[1][4].

2. Wound Healing and Skin Regeneration: It has been indicated for its potential in wound healing and skin regeneration, which is beneficial for repairing damaged skin and promoting the growth of new tissue[1].

3. Anti-photoaging Effects: Research has shown that carboxymethyl chitosan can have anti-photoaging effects, which may protect the skin from the aging effects of ultraviolet radiation[1].

4. Antibacterial Activity: The antibacterial properties of carboxymethyl chitosan contribute to its use in preventing infections and maintaining skin health[1].

5. Safety and Efficacy in Skin Treatments: A study assessing the safety and efficacy of a carboxymethyl chitosan dermal injection device (KIO015) for the treatment of skin defects associated with aging found that it was well tolerated, with only expected and transient injection site reactions . The study also showed that the skin became firmer and more elastic, with significant improvement in skin hydration[5].

6. Superior Hydration Maintenance: The same study reported that KIO015 exhibited superior overall maintenance of skin hydration after 10 months compared to a non-cross-linked hyaluronic acid-based device[5].

7. Antioxidant Capacity: In vitro assessments of KIO015's antioxidant capacity supported its potential protective effects on the skin[5].

These benefits highlight the multifunctional role of carboxymethyl chitosan in skin care and its potential as an ingredient in cosmetic and medical applications for improving skin health and treating age-related skin defects.
