Comparative effects of MKARE® eggshell membrane and hydrolyzed collagen as nutricosmetics on skin biophysical properties: a randomized clinical trial.

In the pilot phase, MKARE® intake led to a nearly 20% increase in firmness and an approximately 40% rise in hydration, outperforming placebo in firmness and showing a clear trend toward superior hydration despite variability in the control group.
