Make sure your armpits, feet and hands are dry and clean.
Apply with your fingertips, 2 drops of the mixture on each armpit and/or on each foot and/or 1 drop on each hand.
This synergy can be applied as is, but if you are sensitive, add two drops of the synergy in one tablespoon of your carrier oil, lotion, or cream of choice.
You can repeat the operation morning and night during high stress period (exams, hot day...)
