Essential oils are potent and in too high a concentration may cause sensitivity. It is therefore wise to always dilute in a base oil before being applied to the skin. For facial oils, use a 1-3 per cent dilution, being sure to measure carefully. So to each 15ml of base oil, you add 3 - 9 drops of essential oils. Start with a 1 per cent dilution, and then move up to 3 per cent when you are comfortable with the oils' effect.
Sweet Almond base oil is available in 100ml bottles.
