When I first learned what hyaluronic acid was, I didn’t give it near the appropriate amount of props. Only but a wee beauty enthusiast at the time and on a quest for a skincare routine that touts all the things—hydrating, anti-aging, glow-boosting, and whatnot—I kept throwing darts at the board until I realized one ingredient almost always hit a bullseye. Ta-da...hyaluronic acid.

This one ingredient has literally whipped my skin into shape, and that's entirely due to the fact that it addresses a whole host of woes at once. Dry skin? It holds over 1,000 times its weight in water. Done. Signs of aging? The powerhouse ingredient plumps your skin up something fierce, making fine lines appear diminished almost instantly, all while keeping future fine lines and wrinkles at bay. Presto. Dull complexion? Try not to feel dewy once you combine hyaluronic acid with a glowy foundation. (Charlotte Tilbury Airbrush Flawless if you want to feel like a goddess divine.) Boom. Basically if you’re not using hyaluronic acid, consider most of your skin concerns explained.

And so my love affair with hyaluronic acid began, slowly at first with just HA-infused face creams like Neutrogena Hydro Boost Water Gel and then full-fledged with HA serums to be layered underneath said moisturizer for extra oomph. Bonus points if my skin is still damp from the shower. Those open pores drink the stuff right up, let me tell you. (Hot tip: Something should be hitting your face within one minute of getting out of the shower for optimal hydration. Run like the wind.)

Out of all the hyaluronic acid serums I’ve tried on the quest to find the best, some of which were painfully pricey, one stood out—and the fact that it was a drugstore find blew my mind even more. I’ve been using Loréal’s RevitaLift 1.5% Pure Hyaluronic Acid Serum for months now, and it has officially cracked the high Holy Grail level of my skincare routine. And whenever my stash is starting to run low, pure anxiety has me screeching my way to the closest CVS, sweat beading on the upper lip.

Part of the brand’s dermatologist-validated Derm Intensives line, the serum blends two types of hyaluronic acid (low weight and high weight) to secure a potent 1.5% blend that makes major moves in both the hydration and anti-aging departments. It’s also made without synthetic dye, mineral oil, fragrance, or parabens, which is a perk for sensitive skin types like mine.

After a few days, you’ll start noticing how much more hydrated your skin looks and feels—that’s the baseline perk. After two weeks of continuous use, you’re expected to notice that the appearance of fine lines has diminished. For me, that means my skin looks plump and more awake, and it’s definitely noticeable. Layered with my trusty age-defying foundation Chantecaille Future Skin Gel Foundation, it can’t be beat.

Incorporating this serum into your own routine is simple. Use it after any active ingredients like salicylic acid or vitamin C and then layer with a more robust moisturizer (such as Olay Regenerist Micro-Sculpting Cream) to lock it all in. It says to use two to three drops, but I’ve translated that to at least half a dropper, if not more. The extra dose has me hooked.

If you’ve never used a hyaluronic acid serum before, lucky you. Things are about to get plump and dewy up in here.

My love story with hyaluronic acid might not be over, but for now I’m in a committed relationship.
