New peptide cream promises healthier, more hydrated skin

This study tests a face cream with a peptide called Acetyl Hexapeptide-37 to see if it improves skin hydration and strengthens the skin barrier. Thirty healthy adults will apply the peptide cream to one side of their face and a placebo cream to the other side daily for four weeks. Researchers will measure skin moisture, water loss, and redness to check for benefits and tolerability.
