I was super excited when BB said this product was the new best thing on the market. I had a really bad breakout of an allergic reaction. Initially this product dried out the marks that appeared. My that time of the month break outs were also way less than normally. The existing blemishes didn't really have any change in color.
My bottle is now in half and i do not know if i would buy a new one. It is also pretty expensive if you are living on a tight budget.
Good to remove current blemishes, to remove past blemish marks no.
