There is acne, tumour like zits, then juice ance, those little stuborn fuckers that you can't even squeeze. Which are you refering to?
You can try all of the above tricks and tips but "if you gunna get zits, your gunna get zits." All the above will be great for natural uncomplicated acne. If you got acne due to hormonal imbalance, there is little to be done working from the outside. To get any relief, antibiotics or abstenance for gas are your only two options.
Accutane is expensive and makes you worse before you get any better. 4-8 months of worse if you know what I mean. Zit Farm City.
Evening Primrose and EFA's are supposed to help balance hormones but they dont do shit after you've pushed grams of test into your system.
I was once plagued with acne from 16-27ish. 80% of it was from gasin'. I never got zits while on, weeks later after. I never really thought long enough about it to make the connection that my post cycle readjustment was a major cause of my zittieness.
