One of the best Vitamin C Serums I have ever tried. I liked that it actually feels ultra clean when you apply it to your face and not gunky like some of these other ones. It is super smooth, light & almost has no scent. But what I loved most about this product from Oz Naturals is that it truly makes your face glow & look beyond healthy. I really love that this is a high quality serum that you can see instant results. It made me look like I had the best night of sleep and my face looked younger.
