Since Vitamin C serums are great for glowing skin, I was excited to try the I Dew Care Vitamin C serum. I used to use The Ordinary Vitamin C suspension 23% about a year and a half ago, but I stopped because the formula really irritated my skin. When I Dew Care gifted me the Bright Side Up serum, I was cautiously optimistic that I could reintroduce Vitamin C into my routine again.
