I have used this for several years and it has been the only moisturiser to control my acne.
I was introduced to it at the height of a hormonal acne flare up and have never looked back.
It may seem a dinky bottle but mine lasts many months, and in the summer I mix it with the solar booster on holiday - no more breakouts from sun lotion either!!
It is very runny and sinks in immediately. My skin is now a little less oily so I alternate depending on how oily/dry my skin feels. As soon as I have a flare up though this works a treat!
Seriously recommend for acne sufferers. I tried everything over many years and this worked the best of them all( roaccutane, benzyl Peroxide etc)
