What are they?

Here at PCA SKIN, we talk a lot — a lot — about peptides and all the magic they do for your skin. But, what are peptides and why are we so obsessed with them?

Essentially, peptides are thinkers. They tell our cells what to do and the most organized way to do it, making them beneficial in your skincare products because they can change the way your skin functions from the inside.

A peptide is the chemical compound of two or more amino acids — the building blocks of protein in the skin — joined by a peptide bond. 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 our skin, telling it what to do and prompting certain skin replenishing proteins to be formed.

PCA SKIN uses next generation peptides, meaning they are the most up-to-date, scientifically engineered and backed by research.

ExLinea® Peptide Smoothing Serum is the only PCA SKIN product that features the peptide Argireline that actively works for 12 hours to visibly reduce the appearance of fine lines and wrinkles upon application.

Perfecting Neck & Décolleté and Total Strength Serum both contain palmitoyl tripeptide-38, which increases the production of three different types of collagen, among other skin components, to strengthen skin, leading to a smoother, more youthful appearance.

Peptides offer your skincare a scientifically backed way of rebuilding skin tissues from the inside out, the most efficient way possible.
