Whether or not you have reactive skin, it’s always a good idea to have a flexible skin care routine that evolves as the seasons (and your skin’s needs) change. A dry, parched complexion is a common symptom, but one that can be remedied with effective and powerful over-the-counter ingredients that won’t break the bank. Hyaluronic acid is a great humectant that is commonly used in both high-end and affordable skin care serums. It can help retain moisture in even the most withered skin, making it a fabulous option for anyone who wants to up their hydration game. Luckily for those of us in need, the Good Molecules brand has a wildly popular and extremely highly-rated hyaluronic acid serum that’s as potent as it is affordable. Marquaysa Battle/HuffPostHuffPost Shopping editor Marquaysa Battle uses this serum daily.This serum has a 4.7 out of 5-star rating at Amazon and over 7,300 5-star reviews.It’s a favorite among skin care enthusiasts thanks to its long-lasting formulation that features two different kinds of hyaluronic acid. It can help to smooth and plump skin, leaving it moisturized, firm and glowy. HuffPost Shopping editor Marquaysa Battle speaks very highly of this nourishing serum. “An aesthetician deemed my skin severely dehydrated a month ago and recommended I add hyaluronic acid serum to my skin care routine immediately,” she said. “I’d already been trying the one by CeraVe but it obviously wasn’t working. So, a friend recommended I switch to Good Molecule’s hyaluronic acid serum instead and it literally changed my skin on the very first use. It has more slip than the one from CeraVe, doesn’t irritate my skin, a little goes a long way and it’s literally the singular secret weapon that stopped the rest of my skincare routine from becoming wholly obsolete this winter. My once parched, tight face now has its bounce and glow back. I’m buying this on repeat!”The Good Molecules hyaluronic acid serum is gentle enough to use daily both morning and night and will pair beautifully with the rest of your skin care routine. It’s good for all skin types and is vegan, gluten-, fragrance- and cruelty-free.Join legions of devoted reviewers (along with our very own shopping editor) and grab a bottle for yourself to find out why shoppers keep purchasing this beauty over and over again.Promising reviews:“Amazing product with great results. I was really skeptical for the price, but I have an amazing esthetician who, because of her own health issues, has to look for clean products with particular standards. After my hydrodermabrasion, I asked for some face product suggestions for maintenance and makeup. This was one of them— I couldn’t believe the quality for the price. Within two days, I started seeing results— so much so I’ve gone without makeup which isn’t usual for me. My skin looks brighter, hydrated, and healthier. I will definitely keep using.” — Whitney Duvall“The Good Molecules Hyaluronic Acid Serum is a great product for those who are in need of a hyaluronic acid serum in a budget! I have really oily skin and my face doesn’t feel stripped when I add this alongside my creamy toner. Overall, it doesn’t hurt to try this product as it is in the budget side as well as clean ingredients with full transparency! (P.S. I’ve bought more than 3 bottles ever since!)” — Czar Ryan Palomar“Wow, impressed. Haven’t had great luck in skincare products lately. Until I found this stuff!
