Chitooligosaccharide

1. Definition Chitooligosaccharide:

Chitooligosaccharide is a natural polysaccharide derived from chitin, a substance found in the exoskeletons of crustaceans such as shrimp, crabs, and lobsters. It is composed of a short chain of chitosan molecules and is known for its moisturizing, anti-aging, and skin-repairing properties.

2. Use:

Chitooligosaccharide is commonly used in cosmetics for its ability to improve skin hydration, reduce inflammation, and promote collagen production. It is often found in moisturizers, serums, and anti-aging creams to help maintain skin elasticity and firmness.

3. Usage Chitooligosaccharide:

When using cosmetics containing chitooligosaccharide, it is important to patch test the product first to ensure that you do not have any allergic reactions. It is recommended to start with a small amount of the product and gradually increase the frequency of use to assess how your skin reacts. It is also important to follow the instructions provided by the manufacturer for the best results.
