Our pure quality essential oils are not diluted with carrier oils. They contain nothing other than the essence of the plant they are extracted from, the plant oil itself. Since the oils are 100% pure, you may need to dilute it before your application. Many essential oils can be applied neat to the skin, however, it is always advisable to test on your skin for sensitivity first. Essential oils are easily absorbed through the skin and into the breath passageways to work with your body for medicinal and aromatherapy purposes. We know you will love the quality of our pure essential oils. We choose only the best to work with in our products and pass the savings on to you by providing them in 10ml dropper bottles.
