I have used this for the last 4 years, together with the byoglycolic facial cleanser and the spf 30 daily face protector. It seems ridiculously expensive but is well worth it if you have adult acne prone skin. Horrifyingly, my "teenage" acne returned when I came off the pill 4 years ago and this was recommended by a beauty salon. I was very sceptical at first on the basis that nothing you put on your skin can combat acne caused by hormones (PCOS), but it really does work. I am 48 and my skin has never been better. It also seems to even out tone and minimise wrinkles. As it is so expensive I have tried periods of not using it but the problems return, to disappear again within days of restarting. I have also used the transformation cream, which is gorgeous but my skin doesn't "need" it the way it does the byoglycolic range.
