This study attempted to investigate the influence of cosmetics containing hydrolyzed collagen protein ‘2000DA low-molecular-weight collagen (LMWC)’ on skin through a human study. A total of 24 participants (12: control group, 12: experimental group) were tested by a double-blind test. The products (3 LMWC-free cosmetic products for the control group, 3 different products with 1% LMWC for the experimental group) were applied in the morning and in the evening every day over 6 weeks. Then, changes in skin conditions were examined. In the control group, no statistically significant change was found in terms of pore index, facial wrinkle index, coarseness index, UV pigmentation index, redness index, sebum index and moisture index. In the experimental group, the coarseness index decreased while the moisture index increased with statistical significance. However, no significant change was observed in pore index, facial wrinkle index, UV pigmentation index, redness index and sebum index. The above results confirm that 2000DA LMWC is valuable as a cosmetic ingredient which protects skin from external aggressors and keeps it moist by maintaining a skin barrier and enhancing skin coarseness.
