Pentapeptide-3 is a synthetic peptide that can inhibit muscle contractions as competitive antagonist at the muscle-type nicotinic

acetylcholine receptor.

Pentapeptide-3 is a topical alternative to muscle relaxing injections. It's an intensive anti-wrinkle care, especially for the fighting against expression lines.

Palmitoyl Pentapeptide-3 was discovered through two branches of dermatological research: the search for substances that accelerate healing skin wounds and the study of what causes wrinkles.

Similarly to copper peptides, Matrixyl stimulates the lower layers of the skin to heal themselves, thus accelerating the healing of wounds.

Cells called fibroblasts are responsible for knitting together wounds of the skin.

Palmitoyl Pentapeptide-3 stimulates the "matrix" layers in the skin -- primarily collagen and fibronectin. When stimulated, the

skin produces more collagen. Loss of collagen is what leads to thinning skin and the wrinkling of newly inelastic skin. 

Matrixyl helps to counteract this natural part of the aging process.
