Plenty of celebrities out there will offer you a $0 tip for hydrating your skin: Drink more water. While—yes—this is helpful advice, it's only part of the equation. In order to truly quench dry skin, you need to supplement your H2O guzzling with topical hydrators, too. The good news? One of the best products for getting the job done costs only slightly more than a glass of tap water.

The Ordinary Hyaluronic Acid 2% + B5 ($7)—which happens to be one of Sephora's top-selling serums—has got the dermatologist stamp of approval for treating dry skin. Shari Sperling, MD, a board-certified dermatologist based in New Jersey, calls it “a great moisturizer that helps with skin hydration.” The formula is made with a 2 percent concentration of hyaluronic acid, which acts as a humectant (think: sponge) to draw moisture into the surface of your skin. It combines low, medium, and high molecular weight hyaluronic acid, and each molecule penetrates the skin at different levels to deliver multi-depth hydration throughout your epidermis. In addition to hyaluronic acid, the serum also contains vitamin B5, which studies have shown to help significantly decrease transepidermal water loss. In other words, not only does the formula infuse your skin with moisture, but it also locks it in for the long haul.

All of this for only $7? It's no wonder the serum has earned more than 1,000 five-star reviews on Sephora's website. "I typically swap my serums out constantly, but this one has made a place in my usual skin-care routine. It’s one of the few things I use that makes such a noticeable difference, making my skin look plump, hydrated, and glowing," writes one reviewer. "I don’t go a day without using this! My skin is so much softer and radiant because I’ve added this serum to my routine," adds another.

With this, plus your $0 glass of water, your skin hydration routine will be the most affordable thing you invest in all winter.
