When it comes to getting hydrated, dewy skin, hyaluronic acid is essential. It helps combat dry patches, amps up hydration and makes a great addition to practically any skincare routine. According to a study in the National Library of Medicine, while your skin has natural stores of hyaluronic acid, these levels decrease with age. To avoid missing out on moisture, consider adding a hyaluronic acid serum to your skincare routine. Ahead, find some of the best hyaluronic acid serums (plus details on what we love about each product) that will give your skin a boost of much-needed hydration.What Is Hyaluronic Acid Serum — and What Does It Do?Hyaluronic acid is a powerhouse skincare ingredient that can carry 1,000 times its weight in water, so using a few drops of it morning and night is a great way to increase moisture. In other words, it pulls water into your skin. It also has plumping effects, so it’s great for combating signs of aging like fine lines, wrinkles and loss of elasticity. While many different types of skincare products are formulated with hyaluronic acid, using a serum is a potent and effective way to incorporate the ingredient into your routine. When to Use Hyaluronic Acid SerumAs with other kinds of serums, hyaluronic acid serum makes an ideal second step in your skincare routine after cleansing. Depending on your skincare needs and concerns, you can follow it up with moisturizer or wear it on its own. Hyaluronic acid serums can typically be used twice a day — in the mornings and evenings — but be sure to follow the instructions on the package or consult with a board-certified dermatologist. The Best Hyaluronic Acid SerumsSkinCeuticals Hyaluronic Acid Intensifier Formulated with pure hyaluronic acid, proxylane and botanical extracts, this serum hydrates the surface layer of the skin, improves the appearance of fine lines and increases hyaluronic acid levels by 30%. Upon initial application, it’s a little thicker and has a heavier viscosity than you might expect. But once you press  it into the skin, the product feels weightless. When our editors incorporated this into both their morning and nighttime routines for two months, their skin appeared plumper, healthier and looked more youthful than pre-use. La Roche-Posay Hyalu B5 Hyaluronic Acid Serum Winter can be hard on skin. The dry air and cold temperatures tend to wreak havoc on our complexions, leaving us with dry patches. Thankfully, the La Roche-Posay Hyalu B5 Hyaluronic Acid Serum gives an extra boost of hydration. This serum amps up its effectiveness by including vitamin B5, an ingredient that helps repair the skin’s moisture barrier and promote long-lasting hydration.  Vichy Aqualia Thermal Face SerumUse the Vichy Aqualia Thermal Face Serum to boost and lock in moisture for an impressive 48 hours. It also helps support the skin’s moisture barrier function. The best thing about this serum? It won’t feel sticky or oily on your skin. Garnier Green Labs Hyalu-Aloe Super Hydrating 3 in 1 Serum Gel with Hyaluronic Acid + Aloe VeraWe love this product because it combines three different skincare essentials — a moisturizer, an eye gel and a hyaluronic acid serum — in one. Enriched with hyaluronic acid and aloe vera, it feels comfortable and refreshing as it absorbs into your skin, leaving behind no residue. Since it’s also an eye cream, it helps minimize under-eye puffiness.   CeraVe Hydrating Hyaluronic Acid Serum One of our main concerns when adding a new serum to our skincare routine is how it will wear throughout the day. Will it pill under makeup? Will it dry us out in the long run? Is it a solution-driven product or just a short-lived fix? With the CeraVe Hydrating Hyaluronic Acid Serum, we don’t have to worry about these problems. The texture is gel-like but extremely hydrating, so we feel comfortable using it as either a replacement for our moisturizer or as an additional step in our routine. With three ceramides and vitamin B5 in the formula, the serum helps to restore skin and promote a healthy moisture barrier. Plus, the product has MVE patented technology, so it continues to release moisture for 24 hours rather than providing only short-lived relief post-application. Youth to the People Triple Peptide + Cactus Oasis SerumIf you want plumper, firmer skin, try the Youth to the People Triple Peptide + Cactus Oasis Serum.
