This Barrier-Repair Serum is Made With an Ingredient That’s 4 Times More Hydrating Than Hyaluronic Acid

Harsh winter temperatures, wind, and low humidity are the perfect recipe for disrupting your skin barrier. The key to keeping it strong? Hydration, hydration, hydration. The more hydration you can get your skin to absorb and retain, the better. That’s why Skinfix launched a new serum that’s packed with polyglutamic acid, a molecule that’s four times more effective at retaining hydration than the reigning humectant queen, hyaluronic acid.

“Polyglutamic acid is similar to hyaluronic acid in that it adds moisture to your skin, and it actually improves your skin’s ability to absorb moisture,” saysShari Sperling, DO, a board-certified dermatologist. What puts PA a cut above HA, though, is that it creates a film on the skin that prevents water from evaporating. So if you feel like your usual moisturizer stops working the minute you step outside, priming your skin with Skinfix Barrier+ Triple Lipid + Collagen + Niacinamide Activating Serum ($69) will help you lock it in.

Beyond polyglutemic acid, the Skinfix Barrier+ Triple Lipid Serum also contains a patent-pending peptide blend that firms skin by boosting ceramides, collagen, elastin, and hyaluronic acid. It also contains niacinamide, a soothing and brightening antioxidant that helps to regulate oil production—which is especially good news for anyone with combination or oily skin (and, yes—these skin types need moisturizer, too). “Niacinamide has calming and anti-inflammatory properties, which counteract the effects of stress hormones on the skin,” says Shirley Chi, MD, a board-certified dermatologist. “Stress hormones increase oil production on the skin, so decreasing inflammation makes your skin less oily.”

And although polyglutamic acid creates that hydration-sealing film that hyaluronic acid can’t, the formula still contains HA. That’s because they work really well together, explainsJanelle Vega, MD, a board-certified dermatologist. Polyglutamic acid “blocks the function of an enzyme that breaks down your body’s natural hyaluronic acid, called hyaluronidase, so, used in combination with—not in place of—hyaluronic acid, it may have synergistic effects,” says Dr. Vega.

So if you’re looking for a product that will fill your skin with hydration, make your moisturizing routine more effective, and your skin barrier stronger, the Skinfix Barrier+ Triple Lipid Serum is here for you.
