This won't be what you want to hear, but even after clearing my skin "internally" there were some leftovers. Internal cures basically just stop new stuff from occurring they don't really fix what's already there.
For the underground cysts, I had to get cortisone shots. Some of them needed multiple shots.
For small bumps and clogged pores kind of like you're describing, I had to do serious exfoliation + microdermabrasion every 3 days for a number of weeks + a series of chemical peels very close together + manual extraction. I mean I basically had to sand and burn and steam the crap out of my skin to get the buggers. All the "be gentle" people won't like it, but when you've had the same little bumps and clogged pores for YEARS, sometimes the harsh way is the only way that works.
Even if you have a perfect diet, it won't fix the external crap that's already there.
Also for heaven's sake stop the maca root. I don't know where people are getting the idea that it is good for acne. Maca has been used for years by bodybuilders and fitness buffs to INCREASE TESTOSTERONE and that is the opposite of what you want to do for acne.
