For a more persistent problem, first apply diluted Oregano essential oil and then apply Melaleuca.
It is imperative you dilute the Oregano oil in a ratio of at least 2 parts carrier oil (such as fractionated coconut oil) and 1 part Oregano. The Oregano is very strong and will burn the skin if not diluted properly. The 2:1 ratio works well for me, and I have sensitive skin. However, be sure to first apply only a little bit and test before putting on too much. If it burns, add more carrier oil. With Oregano, "less is more".
