HEXAPEPTIDE-14

Safety grade: A

Hexapeptide-14 is a short chain of six amino acids (the building blocks of proteins) that is designed to help improve skin firmness and elasticity. It works by signaling skin cells to produce more supportive proteins, helping to reduce the appearance of fine lines and wrinkles.

This ingredient is used in skincare products to condition and firm the skin by promoting the production of structural proteins, resulting in improved skin texture and a more youthful appearance.
