As a skincare enthusiast, I have tried countless amounts of different hyaluronic acid from many brands. But this one is my absolute favorite that I have ever tried! The formulation is so smooth and velvety, when applying the serum it is so smooth on your skin and doesn’t make you feel sticky or tacky. It settles into the skin so well and 100% I will never use any other hyaluronic acid other than this one!! You need to purchase this and try it! My skin is so moisturized & hydrated and I have noticed a big difference in my skin barrier since I started using this. 10/10 recommend!
