What Are Peptides

This article answers the questions: what are peptides, their uses in skin care products, their benefits for skin. The list of the best reviewed topical products with peptides are provided in the end of the page.

Peptides are molecules which build up from the rest of alpha amino acids (protein).These natural or synthetic compounds consists of tens, hundreds, or thousands of links of amino acids.

In short, peptides are break-down products of protein which our body and skin contain. They are protein mini molecules which build up and restore skin protein cells when penetrated in skin.

As we age, collagen (which is a protein) production in skin and body decreases, skin becomes flabby and wrinkled, and needs our help.

Peptides in Skincare

Peptides are the popular ingredients for skin topical products which claim to have anti-aging benefits, restoration collagen production qualities and wrinkle reduction

Popular peptides you can find in topical products:

Argireline (acetyl hexapeptide-3) is a synthetic ingredient

Copper peptide (copper tripeptide-1) is a natural ingredient

Matrixyl (palmitoyl pentapeptide-4) is a chemically derived molecules

Matrixyl 3000 (palmitoyl oligopeptide & palmitoyl-tetrapeptide-7)

Or/and their combination

Other peptides combos and potent formulas are also widely used

Argireline

Argireline is a synthetic ingredient which is widely used in anti-aging, and anti-wrinkle topical products. It is a commercial name of the molecule acetyl hexapeptide-3. It is also called neuropeptide.

It is claimed to relax muscles and wrinkles working topically similar to Botox.The results of several studies on the benefits of Argireline in anti-wrinkle products have not been published.

Copper Peptide

Copper peptide (copper tripeptide-1) is a natural ingredient which naturally occurs in human urine, blood, and saliva. It is non-toxic and non-irritating for skin.

Many anti-aging skin-care products are formulated with copper peptide. Studies have confirmed its anti-aging properties, ability to firm skin, reduce fine lines and wrinkles, promote cells collagen production, ability to restore cells, regenerate skin, reduce scars, and improve the appearance of skin.

Studies also prove that copper peptide is more efficient than vitamin C, and retinol (retinoic acid) - the popular skin-care anti-aging ingredients.

Matryxil

Matryxil (palmitoyl pentapeptide-4) and Matryxil 300 (palmitoyl oligopeptide & palmitoyl-tetrapeptide-7) are both chemically derived molecules. They have different structures, and only their names link them. Matryxil 300 is a newer version of Matrixyl.

Studies on Matryxil 300 confirm its anti-aging benefits, and ability to reduce fine lines and wrinkles up to 44%, tight and firm skin …Matrixyl 300 performance report.

I conducted research on topical products with peptides in order to find the best of them which really work. I came across different sites and chose the best peptides topical products reviewed by consumers.

As I was researching, I found that in order for a peptide product to better penetrate into the skin, peptides have to have a stable formula (they become unstable in a water-based formulation) in order to reach cells in lower epidermis layers.

The other main ingredients in products should have a small molecular formula, as well, to pair with peptides and work together on cellular level.
