Our base oils are greasy vegetable oils and act as carrier oils for the essential oils. When choosing, Sue always makes sure that the base oils have a variety of nutrients and polyunsaturated fatty acids. Greasy plant oils are very similar to our skin fats, are well absorbed by the skin and therefore penetrate deep into the skin layers and are included in the metabolism. Base oils and essential oils support each other in their healing power by naturally strengthening the skin's protective and defense system and our immune system.
