SH-HEXAPEPTIDE-3

Safety grade: A

This lab-created peptide (a tiny protein fragment) works to relax facial muscles and smooth the appearance of fine lines and wrinkles, particularly on the forehead and between the brows. It's designed to mimic the skin-relaxing effects of more complex treatments, making it a gentler alternative in anti-aging skincare products.
