Has Kojic acid and can be used daily without drying skin
One of my favorite products ever. I highly recommend this especially if you have dry skin. I find that using hyaluronic acid can sometimes make my skin even dryer and this has Kojic acid in it which gave me the ability to use it daily without drying my skin. It gives your skin a beautiful glow like you've put honey on your face. I absolutely love this product!
