An anti-aging tetrapeptide that works to keep skin youthful, addressing firmness and sagginess by helping to inhibit protein-degrading enzymes within skin’s surface.

An anti-aging tetrapeptide that works to keep skin youthful, addressing firmness and sagginess by helping to inhibit protein-degrading enzymes within skin’s surface.

A lab-made skin-firming peptide formed from a reaction between acetic acid, cetyl alcohol, and dipeptide-1, which contains the amino acids arginine and tyrosine.

Acetyl hexapeptide-1 is a synthetic peptide composed of the amino acids alanine, arginine, histidine, leucine, phenylalanine and tryptophan.

This synthetic peptide is composed of amino acids (alanine, proline, serine, and glycine). It works to help skin’s layers maintain adequate hydration.

One of several peptides used in skin care products, this ingredient has skin-restoring and water-binding properties, helping it improve both the look and feel of skin.

A synthetic peptide that is based around octapeptide-3, a peptide complex composed of the amino acids aspartic acid, glutamic acid, glutamine, and methionine.

Often called simply "hexapeptide-5", this peptide is derived from the versatile protein versican, which plays a role in skin’s extracellular matrix. Topical use promotes a firmer look and feel.
