I had tried this Vitamin C Serum, it . I have tried several of them and this is a nice one too. This did help brighten my dull skin and also gave me nice glow. This one has Vitamin E and Hyaluronic Acid inside of it as well which helps the any wrinkles if you have them. Also helps to bring the collagen back into the skin to make your face the way it once was with more elasticity This one I did have to use a moisturizer with it because it had made my skin a little dry when I first starting using it. But it still does the job very well. They make this product in the USA which is great we need to support our USA. Also love that they use plant based ingredients as well in their product. They don't do animal testing on animals which is a major plus to me. I received this product for free for my unbiased opinion and my opinion is solely my own.
