My brother actually had a bad problem with pimples etc. something that actually helped him quite a bit and didn't cost him much was a tanning bed. He went once and the bed fried up most of them. There are probably other alternatives out there. but it's just some food for thought
regular tooth paste, not the gel stuff. just apply before going to bed (wait for it to dry) and then when you wake up wash off any remainder
it may not work for everyone and besides you can buy a small tube of regular paste at walmart for under a dollar if it doesn't work for you then you just lost a buck...
Tea Tree is a natural antiseptic. Place a dab on acne or add one drop of tea tree oil to warm water and place on the area where there is acne. Tea Tree Oil soap also is very effective. You can also apply lavender essential oil to your acne.
