Both Tea tree and aloe vera oils have properties that might clear acne, says Nerys Purchon in her book "The Essential Natural Health Bible." Aloe vera oil is made of a small amount of aloe infused into a carrier oil such as almond or grapeseed oil, explain Carol and David Schiller in their book "Aromatherapy Oils: A Complete Guide." Since tea tree oil is a concentrated essential oil, the aloe and carrier oil blend can dilute the tea tree enough for it to be applied to the skin.
Pour 3.5 oz. of aloe vera oil into a liquid measuring pitcher.
Drop 40 to 60 drops of tea tree essential oil into the aloe vera oil.
Mix the oils with a spoon.
Pour the oils into a dark-colored bottle with a lid to store.
Apply oil to acne with fingers or a cotton ball.
