The best way to get rid of acne is to be ten years older! All teenagers get some form of acne because they are growing through a hormonal storm, which is adolescence. The answer truly is to eat real food and drink more water - fresh vegetables and fruit, much less meat and nothing sugary at all. An effective method you can use is to make up a Calendula Tea - a third of a cup of chopped up Calendula flowers (Marigold, Calendula officinalis) topped up with boiling water - cool and strain. Cleanse the affected area daily (cotton wool helps) and make up fresh Calendula Tea once a week. I suggest you book an appointment with a Naturopath, Herbalist or Homeopath and they will guide you towards a beautiful complexion.
