I wish I knew back in my teens what I know now. Raw garlic combined with removing dairy products and excess sugar will dramatically reduce acne. It takes about two weeks to notice a difference however. Firstly avoid all dairy and reduce sugar. (These mess with hormones and cause insulin spikes which also mess with hormones). With the garlic, buy fresh bulbs and consume more to start with. Before meals peel one or two cloves of garlic and chop the peeled clove into small pieces. Gather the pieces in your hand and drink down with water. After a few days reduce the amount. Eventually, after a week or so just peel one clove of garlic, chop into tiny pieces and drink down. It definitely works. You also notice the difference when you stop taking the garlic. Also, wash your face no more than twice a day with a gentle glycerin soap. The skin needs to be lubricated to allow solidified sebum to escape from the pores. Use cold water.
