This product didn’t work for me. I used as directed and it made me break out for the entire duration of usage. At first I thought this was purging and so stuck with it, but I continued to break out over a 2 month period. It also did not do anything for my dark spots — it just left me with more acne and thus, more dark spots. I had better success with products with kojic acid (ie Mario Badescu’s whitening mask) that were 1/2 the price.
