I normally don't write reviews - everyone says that - but for the cost of this product, I think you can do much better. My friend brought this with her from the States when she came to visit me (I am in New Zealand). At first I liked it quite a bit. I did notice that when I put it on existing blemishes, the blemishes went away quicker than they normally would. Which was great. But it did nothing absolutely to slow down the pace of the blemishes from coming. In fact, I would say that I almost felt that since I began to use it, my overall acne got worse, which was fairly depressing. I continued to use it with those blemishes until the bottle was complete but getting another bottle from the States was out of the question. Ironically, the brand I ended up going with, after much research, was also from the states. A considerably lower price per bottle, for larger bottles! and preventative! Ninja Skincare is the only brand I have ever found to clear up my skin after nearly 20 years - so spot treatments like Kate Sommerville aren't even necessary to have on hand any more! I don't even wear makeup any more to cover up blemishes! So the added cost of shipping from the States is well worth my self esteem improving and actually spending less on products on a monthly basis! I guess I would just end by saying, if you need a spot treatment this is ok as far as spot treatments go. But personally, I just didn't want to have spots at all any more ever!
