What are peptides used for in cosmetics?

As we age, the skin loses density in the dermis, due to a decrease in the production of fibroblasts, cells responsible for the synthesis of collagen, elastin and fibronectin, thus leading to the appearance of wrinkles and loss of skin firmness. This is where peptides have been shown to play an important role in combating the signs of skin aging.

Peptides are two or more amino acids linked in a chain, capable of stimulating the synthesis of proteins by fibroblasts, attenuating visible wrinkles and loss of skin density, also functioning as carriers of cofactors for skin healing.

Peptides perform many important biological functions in our skin and are classified into 3 groups:

• Signal peptides: these are peptides that activate fibroblasts, leading to an increase in the synthesis of collagen, elastin, fibronectin, PTGs and GAGs, effectively treating wrinkles and sagging, in addition to improving the skin's healing process. (eg Palmitoyl Pentapetide-4 or Hexapeptide-10)
• Carrier peptides: these are substances that transport metals, such as copper, substances that are necessary in enzymatic reactions and in angiogenesis (mechanism for the growth of new blood vessels), increasing the synthesis of type I collagen, elastin, PTGs and GAGs. This type of peptides has antioxidant and anti-inflammatory functions and has also been shown to be effective in wrinkles and skin firmness. (eg Copper Palmitoyl Heptapetide-14, Heptapetide-15 Palmitate or Copper Tripeptide-1)
• Inhibitor peptides: are substances that inhibit the release of neurotransmitters, decreasing muscle contraction, improving the appearance of expression wrinkles. (eg Acetyl hexapeptide-8 or Acetyl hexapeptide-8 or Pentapeptide)

The use of cosmetics with peptides has been growing more and more, where we can find this ingredient in serums, moisturizers, eye contour care or even more specific care, in order to help fight wrinkles and skin sagging .
