Information from PCA Skin about Peptides

What is a peptide and how do they work?

A peptide is the chemical compound of two or more amino acids, the building blocks of protein in the skin, which are joined by a peptide bond, the chemical bond linking two amino acids together.
When these compounds form a long chain, they become a protein.

As a shorter chain, they are able to get deeper into the skin and communicate with cells, telling them what to do and the most organized way to do it, even prompting certain skin replenishing proteins to be formed. Essentially, peptides are thinkers, making them beneficial in skincare products because they can change the way our skin functions from the inside. PCA Skin uses next generation peptides, meaning they are the most up-to-date, scientifically engineered and backed by research. So lets meet some of these powerful peptides…

Acetyl Hexapeptide-8 (Argireline)

This peptide consists of a chain of six amino acids, absorbed by the skin and directed to work by inhibiting the neurotransmitter release from the brain to contract the facial muscle. This ingredient is present in Exlinea® Peptide Smoothing Serum to specifically target the facial muscles that cause repeated facial expression wrinkling, such as crow’s feet, laughter lines, glabellar etc. This peptide is active for 12 hours in the body and has been proven to reduce the appearance of expression lines by 30% in 30 days.

The other key ingredients in this product Sodium Hyaluronate, Squalene & Rice Bran Extract work in synergy with the Argireline peptide to hydrate, smooth and firm aging skin whilst minimizing the appearance of lines and wrinkles.

Myristoyl Nonapeptide-3 (Retinopeptide)

This relatively new discovery is in fact a peptide containing a chain of nine amino acid residues. Once applied topically and then absorbed by the skin this peptide will mimic the activity of retinoic acid (Vitamin A) increasing cellular turnover and also collagen synthesis without any of the potential negative side effects such as irritation or stinging. This peptide is present in Ideal Complex: Revitalizing Eye Gel & Restorative Cream, Intensive Clarity Retinol & Intensive Age Refining Retinol.

Myristoyl Pentapeptide

This cosmetic peptide enables skin to boost collagen synthesis, with a highly anti-aging function of promoting cell regeneration, effectively repairing damaged skin, delaying skin aging, tightening skin and repairing fine lines. It is also potent in the prevention of dark circles & effectively promotes the growth of new eyelashes. Explaining why this particular peptide is also found in Ideal Complex: Revitalizing Eye Gel & Restorative Cream.

Palmitoyl Tripeptide-38

A three-chain amino acid popular in cosmeceutical skin care formulations because its power to penetrate deep into the dermis to boost the production of collagen types 1,3 & 4. Not only this the peptide promotes the synthesis of Hyaluronic Acid, and will assist the body’s natural regeneration process helping skin retain its suppleness. A powerful peptide found in both the Peptide Lip Therapy & Hyaluronic Acid Lip Booster.
