If you have dry skin, you might have heard of hyaluronic acid as a solution — but with so many skin care ingredients becoming buzzwords, from retinol to vitamin C, we don’t blame you if you don’t know offhand what hyaluronic acid even does, or how it works. We’re here to break that down and to let you know about one hyaluronic acid serum in particular that has wowed reviewers.
In previous HuffPost reporting about hyaluronic acid, Joshua Zeichner, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York, explained, “Hyaluronic acid is a natural sugar found in our skin. It is what provides bounce and plumpness to the skin. Think of it like the stuffing in your mattress. As a humectant, hyaluronic acid is essentially a sponge that binds to 1,000 times its weight in water.” While hyaluronic acid can’t deliver 100% of the hydration you need, it can provide a boost.
This boost is why La Roche-Posay’s Hyalu B5 hyaluronic acid serum has become popular, with 4.6 stars across more than 30,000 ratings on Amazon. Allergy-tested and designed to be safe for all skin types, the serum is formulated with hyaluronic acid as well as anti-inflammatory madecassoside and soothing vitamin B5. Together, the ingredients are meant to deliver a hydrating, plumping, anti-aging effect, and plenty of reviewers back up this claim.
