acne has been a problem for me on my shoulders since i was a teenager, Luckaly thats the only area i REALLY break out.. Ingrown hairs are also favorable for me.
What i do to prevent.
Shower EVERY morning, Shower After EVERY workout, or any Sweat senestive activty, IE: Sports, Training, Beach, or skeet skeet skeet..
This keeps your pours as empty as possible, Less likly for oil/dirt to conclude an infection (acne)
Find a pore clenser, or acne medication, Treat the acne prone areas. This should help keep your pores un clogged and clean..
The over all trick to preventing acne for those of you like me who are prone, is keeping your pours clear as possible! Those products do help if you keep your skin maintained!
Check out walmart for products, Or talk to a pharmisist. I tryed to find link to what i use, But i can't find it.. It's just a pore clenser, During my test cycle it had helped me out large.
