I think after years of research, there are only 2 real CURES for acne:
1. Ro-Accutante
This is oral medication in the form of a pill. This pill is extremely powerful and have HUGE side-effects such as drying of your body but the dryness sort of go away once you stop taking the pills. You need to see a dermatologist about this. Ask all the questions first, especially weight the risk of 'side effects' vs 'getting rid of acne'.
How it works? Basically, the root cause of acne is 'accessive oil produce by over active glands' in some people. Ro-accutante attacks this problem by going to the root cause, ie, killing some of the oil glands. The course is about 3-6 months, i think, then you're cured. Maybe, have to take anothe course sometimes in the future.
The reason i know this works is because i have had acne for toooo many years, and literally NOTHING works, tried it all, but roaccutante cured me. I didn't complete the course (because i can't take the side effects) but it already cured 90% of my acne. Nowadays, i get one or two once a while.

2. Laser. This is a very new method that does the same thing as above, ie, kill the oil glands (doesn't really kill, but suppresses the glands), but it does it topically, on the acne areas only so the side effects of drying does not occur on the whole body. This technology is not widely available. I don't know where it actually is.

Be sure you talk to the right Dermatologists, don't ever go to a 'beautician clinic' as they will 'destroy your skin' touting all kinds of treatments that can be more harmful than helpful.
