I used this serum along with some by mi's toner and I'm not satisfied by both. Its been a little more than 3 months now and the only thing its done for my skin is brighten it. I purchased both of them hoping it would help with the active breakouts on my skin but it did nothing for it. It did help with clearing tiny bumps on my forehead and my skin's tone went two shades brighter but I really hoped it would help clear my acne and help in fading the pigmentation but I saw no difference in them so that was quite disappointing. Cos rx's blemish spot clearing serum is similar to the miracle serum and I found that one works much better in receding active breakouts and smoothing the skin so I'd rather purchase the former than the latter.
