"This was gifted to me, and I liked it more than I thought I would. I was a little hesitant up front, it did look a little yellow, but in all fairness it never turned brown on me and it wasn't too irritating. They added a lot of ingredients to help calm and soothe the skin, so even though it's a strong vitamin C serum, my sensitive skin could handle it. That said, I do have a gripe with it. This bottle looks the same size as a 30ml bottle, but it's actually 20 grams, so I finished it off so much faster than my brain could understand, while other companies are doing 50ml serums."
