Chitosan is a product of N-deacetylation of chitin. Chitin, chitosan, and cellulose have similar chemical structures. Cellulose has a hydroxyl group at the C2 position, and chitin and chitosan are respectively replaced by an acetylamino group and an amino group at the C2 position. Chitin and chitosan have many unique properties such as biodegradability, cell affinity, and biological effects, especially chitosan containing free amino groups, which is the only alkaline polysaccharide in natural polysaccharides.
The amino groups in the molecular structure of chitosan are more reactive than the acetylamino groups in chitin molecules, making the polysaccharide have excellent biological functions and the ability to undergo chemical modification reactions. Therefore, chitosan is considered a functional biomaterial with greater potential for application than cellulose.
There is a large amount of chitin in the shells of marine arthropods such as shrimp and crabs, insects, cell membranes of fungi and algae, shells and bones of mollusks, and cell walls of higher plants. Chitin is widely distributed in nature, with reserves second only to cellulose, making it the second largest natural polymer.
Chitosan is currently used as an ingredient in high-end cosmetics for skincare products. It is used in medical beauty procedures such as pulsed light, radiofrequency, dot matrix, and fruit acid to act as a natural antibiotic to resist sensitivity and anti-inflammatory effects, quickly repair basal heat damage, heal wounds, and repair the epidermal barrier. Moreover, chitosan skincare products also have the function of metabolizing heavy metals!
The most impressive thing is that chitosan is a component in the world that can adsorb heavy metals, skin toxins, and hormones! Effectively metabolize heavy metals, hormones, and haze that remain in the skin's lower layers due to long-term makeup. The efficacy of these ox forks has achieved its mythical status in skin beauty and repair!
