No you're not doing anything wrong at all, the Regimen just takes time to work and that time will be different for everyone. Three weeks is very early on in Regimen terms so it's perfectly normal for you to still be breaking out. It took me a lot longer than that to get clear and really you should only be judging whether or not it's working for you after three months or so (although as you pointed out it does work a lot quicker than that for some people). I know it's frustrating, but the Regimen is just one big patience test and only those who stick it out ever get the results they want in the end. Hope it improves for you soon.
