There are three levels of acne and different types at each level. each level needs to be treated differently.
Mild acne - white heads and black heads. simply washing and showering will most likely do the trick.
moderate acne - pustules and rosacea needs to be treated with topical medications you can buy at the store like acne anilater works good. also showering is important.
sever acne - cycstic and nodule acne. none of the above will work. You will need to take antibiotics but sometimes as soon as you finish the anti biotics it comes back. Im not a fan of acutane but it does work. It is hard on the liver and needs to be taken 16-20 weeks. That is a long time to abuse your liver and if your on cycle during this time you might as well put yourself on the liver transplant list.
