COSMETIC COMPOSITION FOR USE IN INCREASING COLLAGEN SYNTHESIS IN SKIN CELLS

摘要

The invention refers to a cosmetic composition for increasing collagen synthesis in skin cells comprising 0.001 - 0.5 wt% of a Phaeodactylum tricornutum extract, 0.00001 - 2.0 wt% of Dimer Tripeptide-43 or Hydroiyzed Rice Protein, and cosmetic auxiliaries. The cosmetic composition comprising the combination of both components has an synergistic effect on collagen I synthesis in skin cells and has a booster effect to other substances which are known to have an enhancing effect to collagen I synthesis.
