Acne Solving problem...

Well I had acne since hmm 12 yrs old only because I was in sweden and ate a lot of sweets and stuff. 'til now I am trying to fight off these s.o.b's but I don't know why I just bought a product like 1-2 months ago that contains "ZINC" and it is working pretty well. After I wash my face with it I use 70% alcohol and I see good results.
and here's my question is Zinc then after alcohol 70% good for ur skin?
