Figure 2. The effect of LMWCP on Skin hydration to depth of 0.5 mm in the stratum corneum using a Moisturemeter D (DXS5). (A) The water content values (A.U.) in the test group and the placebo are presented as mean ±SD. The statistical analysis was performed using the Wilcoxon signed-rank test with **P<0.01, ***P<0.001. (B) Statistical comparisons between the test group and the placebo group were calculated using the Mann-Whitney U test, test using delta values with §§P<0.01, §§§P<0.001 : Oral Supplementation with Low-molecular-weight Collagen Peptide Improves Hydration, Facial Lifting, Dermal Density, Skin Desquamation and Nails: A Randomized, Double-blind, Placebo-controlled, and Maintenance of Effect Study : Science and Education Publishing
