Abstract

The present invention relates to a composition for preventing skin aging containing chitooligosaccharides as an active ingredient. The invention provides a cosmetic composition for preventing skin aging caused by UV rays containing chitooligosaccharides of 1-3 kDa, 3-5 kDa or 5-10 kDa molecular weight as an active ingredient.

Claims

1. A cosmetic composition for preventing skin aging comprising chitooligosaccharide as active ingredient.

2. The cosmetic composition for preventing skin aging of claim 1, wherein the chitooligosaccharide is selected from chitooligosaccharide with molecular weight 1-3 kDa, chitooligosaccharide with molecular weight 3-5 kDa and chitooligosaccharide with molecular weight 5-10 kDa.

3. The cosmetic composition for preventing skin aging of claim 1, wherein the molecular weight of chitooligosaccharide is 3-5 kDa.

4. A cosmetic composition for improving wrinkles of claim 1, wherein the chitooligosaccharide content is from 0.05% to 8% by weight on the basis of the total mass of the composition.

5. The cosmetic composition for preventing skin aging of claim 2, wherein the molecular weight of chitooligosaccharide is 3-5 kDa.
