When I STILL had acne in my late twenties, I did some research. I ditched the products and went for IPL. IPL is not harsh, it's not a laser. It's intense pulsed light. It kills the bacteria that tend to form acne deep in the skin.
Unfortunately I haven't had any IPL recently, so I wouldn't know where to recommend. You should probably do some online research and have a thorough consultation. I had my IPL at The Private Clinic on Harley St, but since then many places are offering IPL.
If you're still thinking you'd rather stick with products, then I'd highly recommend Proactive.[www.proactiv.co.uk
