My advice:
Take Vit C, start with 1gr in two takes and your body will tell you is that is enough. Steam your face and scrub it (not every day, if you don't want to seam it, scrub it after your shawer).
If you can afford it, go for the a decent cleaning cream in the wemen stores and a bacteria killing gel.
And for course, after all this, humect your face with another cream.
You can also do once or twice a cleaning mask.
I know I know, this are girls fu.. things, I use to make this in a dark corner and touch my dick every 5 minutes to be sure that it was still there !!
If you are a teenager, be patient, it will go with the time. Meanwhile try no to mess up you fac poping your acne before is time to do it. You don't want scars.
I has some acne when younger and I managed to maintain it to it's minimun doing all above.
Probably I shouldn't say this, so don't read what's next!
If you are you are in a real hurry and you need your face clean in a week time because you are having the date of your life you can use ...
See ya bro.
