I have always had really oily skin, resulting in bumpy uneven skin and practically an oil slick on my forehead and cheeks within a few hours of cleansing and putting on makeup. But after around 1 week of using this product my skin is the smoothest and brightest it’s been, but most impressive is that there is no oil on the surface of my skin. It’s nothing short of a miracle. After 15 years of trying various budget and high end skincare I’ve never found a product that does what it says like this does. It is non greasy, light and absorbable on the skin. This is the best vitamin C product I’ve ever used. I’m really satisfied as I’m also prone to acne and this product helps calm my sensitive skin. Totally recommended to everyone!
