Peptides And What They Can Do For Your Skin

At COSMEDIX, we know that clean ingredients can make a big difference in skincare formulas. Buzz words and end-all-be-all ingredients rise and fall, but evidence is mounting about benefits that peptides may have for skin’s tone and firmness. Over at Vogue UK, consultant dermatologist Dr. Mary Sommerlad says that “There is good evidence that signal and carrier peptides can make skin look firmer and plumper, with a smoother texture… ”

What Are Peptides?

Peptides are short chains of amino acids that can help build proteins and help skin produce more collagen. Skincare professionals and dermatologists divide peptides into a few categories, but carrier and signal peptides are most commonly used in non-injectable skincare treatments. Not just any product with a peptide ingredient is going to be your best skin solution, though. Read on for tips on best peptide practices, and for some of our favorite peptide-infused COSMEDIX skincare products.

Best Practices for Peptides

The Right Routine… the one that’s right for you, of course

The placement of a peptide in your skincare routine is going to impact its effectiveness. A cleanser with peptides, which gets washed off after use, might not do as much for your skin as it could. Instead, choose a peptide-infused product that soaks into the skin over time. Opt. for an AM/PM serum that stays on your skin all day or all night—we’ll discuss several of our COSMEDIX favorites, like Peptide Rich Defense AM/PM and Affirm Antioxidant Firming Serum, later on.

Peptide Ingredient Collabs

Peptides can work even more effectively to restore a plumper, firmer appearance to skin when they’re used in combination with other active ingredients. Vitamin C, Niacinamide, or Hyaluronic Acid can help peptides with less chance of irritating the skin. Carrier peptides are also quite effective when combined with a Copper Complex. Choose a serum that’s formulated with a combination of a peptide and another powerful ingredient that may address your particular skincare concerns.
