Peptides are found naturally in the body – they are proteins composed of long or short chains of amino acids, which are the building blocks of protein in the skin – more specifically, Collagen. As we age, collagen breaks down and lines, wrinkles, and sagging skin take over. Enter peptides.
Topically applied peptides perform the same task of signaling the cells to form new collagen and reverse the aging trend. When peptides are in a short chain of amino acids, they are able to penetrate the top layer of our skin and send signals to the cells to let them know how to function.
We know this because, initially, peptide research was restricted to wound healing and its ability to cause skin cells to produce more collagen to heal the skin. These studies confirmed the hypothesis and we now reap the benefit of that research and use peptides in cell-rejuvenating topical creams and serums to restore the skin to a more supple, youthful, appearance.
There are different kinds of peptides (we have written about Copper Peptides. ).There are neuropeptides (which work to relax facial muscles, similar to BOTOX). The most popular is called Acetyl Hexapeptide-8 or Argireline. One serum that includes Argireline PCA Skin’s Exlinea Peptide Smoothing Serum pHaze 25.
Some peptides are natural and some are synthetic. Most peptides used in cosmetics are synthetic. That’s because manufactures can ensure stability, quality control and effectiveness – and they are more cost effective to produce in a lab.
Neuropeptides: Boosts the appearance of suppleness and firmness.
Alpha Lipoic Acid: Minimizes the look of fine lines and wrinkles while delivering powerful antioxidant protection.
Vitamin C Ester: Corrects uneven skin tone and light diffusing technology to combat yellow, red, and blue undertones.
Non-Chemical Mineral-Based SPF 30 sun protection from UVA and UVB rays with Zinc Oxide and Titanium Dioxide.
Other product combinations provide an anti-aging boost to peptides. Like retinol and peptides. Prolonged skin inflammation can accelerate the aging process. If you are currently using a retinol product and need and extra boost – add some peptides. Combining them with a retinol can offer a gentle but effective anti-aging boost like this product from SkinMedica Retinol Complex 1.0 – is best when used at night and topped with a moisturizer.
