What are peptides and how do they help the skin?
Peptides are chains of amino acids. Peptides are thought to send signals or stimulate the skin to behave in a different way. It is believed that certain sequences of amino acids produce different effects when exposed to the skin. Probably the most well known in skin care products is a peptide called palmitoyl pentapeptide-3, commercially know as Matrixyl. This peptide helps to improve the firmness of the skin. Based on documented research, this peptide stimulates collagen production in the skin and also increases the amount of water-binding substances in the dermis. Regular use of this product can improve the appearance of fine lines, wrinkles, firmness, and elasticity.
Another well known peptide is acetyl hexapeptide-3, commercially known as Argireline. This product has anti-wrinkle properties and is often promoted and used to treat expression lines, but it can be used on any type of wrinkles. The peptide works by inhibiting certain binding proteins that create the tension that causes wrinkling. There are other types of peptides now available in skin care products that can help with elasticity, puffiness, fluid retention, and other esthetic problems. Peptides are being used in serums, moisturizers, eye creams, and other types of products. To have a real lasting effect on the skin, peptide products must be used consistently, solid results can not be expected from periodic use. Peptides can be used in conjunction with other products to minimize the appearance of aging, including sunscreens, AHA products, antioxidants, lipid-based products, and moisturizers. A combination of all these ingredient types in a planned program for daily application can produce substantial improvement in appearance of age or sun damage related wrinkling, elastosis, puffiness, and other visible signs of aging.
