Hyaluronic acid, the cure-all for dry skin and fine lines. This category is teeming with skincare products that boast the moisture-locking properties of hyaluronic acid. If you're looking for some added hydration to your skincare routine, look no further than the vast selection of serums, gels, and creams. But the trend doesn't just stop at skincare. Collagen supplements and marine collagen peptides also piggyback off of the hyaluronic acid hype for their anti-aging benefits. And let's not forget about the all-important sunscreen, which has also jumped on the hyaluronic acid train to provide not only protection but hydration. This category is all about creating that dewy, plump skin look that we all strive for.
