Cosmetic peptides are short chains of amino acids that are used in skincare products to support various skin functions. Peptides are naturally occurring substances in the skin that help to maintain its structure, function, and appearance. However, cosmetic peptides are usually made in a laboratory using synthetic methods.
Cosmetic peptides work by penetrating the skin and interacting with skin cells to stimulate collagen production, promote hydration, increase skin elasticity, and reduce the appearance of fine lines and wrinkles. They have small molecular sizes that enable them to penetrate the skin more deeply than other larger molecules.
Some common types of cosmetic peptides used in skincare products include:
Copper peptides: These peptides help to promote collagen production and improve skin firmness and elasticity.
Palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7: These peptides work together to reduce the appearance of fine lines and wrinkles by stimulating collagen production.
Acetyl hexapeptide-8: This peptide is commonly known as “Botox in a bottle” because it helps to reduce the appearance of expression lines by relaxing facial muscles.
Tetrapeptide-26: This peptide has hydrating properties that help to improve skin moisture levels and promote a healthy skin barrier.
Overall, cosmetic peptides have become increasingly popular in skincare products due to their ability to support various skin functions and improve overall skin health. However, it is essential to note that not all peptides work for everyone, and it’s always recommended to patch test any new skincare product before using it on your entire face.
