Understanding the Power Players: Peptides and Glycolic Acid

Peptides are short chains of amino acids that act as the building blocks of proteins like collagen and elastin. In skincare, they signal to your skin to produce more collagen, which can lead to firmer, smoother, and more youthful-looking skin. There are various types of peptides, each with specific functions, from signaling peptides to carrier peptides and enzyme inhibitor peptides.The most popular serums with lactic acid glycolic acid copolymer on SkinSort is theNaturium Multi-Peptide Advanced Serum.

Glycolic acid, on the other hand, is a popular member of the alpha-hydroxy acid (AHA) family. Its small molecular size allows it to penetrate the skin effectively, making it a potent exfoliant. Glycolic acid works by dissolving the bonds between dead skin cells, promoting cell turnover and revealing brighter, more even-toned skinCan I use Glycolic Acid with Niacinamide together? - Loreal Paris.

Some experts even state that AHA's such as Salicylic Acid & Glycolic Acid can hinder the efficacy of peptides. This is because acids with a low pH can decrease the effectiveness of some anti-aging ingredients if layered together.

The argument here is that ingredients that boost peptide penetration can include glycolic acid. By exfoliating the skin, glycolic acid can remove the outermost layer of dead skin cells, potentially allowing peptides to penetrate more effectively into the deeper layers of the skin where they can exert their collagen-boosting effects.

The key to this approach lies in careful timing and formulation. Some suggest that you can apply glycolic acid in the evening and peptides in the morning, or alternate nights to avoid any potential negative interactions. This strategy allows the exfoliating benefits of glycolic acid to occur without immediately interfering with the peptide application.Layering Order: Applyglycolic acidfirst, as it has a lower pH, which allows it to exfoliate the skin and prepare it for the absorption of other ingredients.

It's also worth noting that some advanced skincare formulations, like the Naturium Multi-Peptide Advanced Serum, might contain a blend of ingredients including glycolic acid copolymer, suggesting that formulators are finding ways to stabilize and combine these potent ingredients. This indicates that the future of skincare might see more sophisticated ways to harness the benefits of both.
