Oil blends have been used on skin for thousands of years, and are seeing a resurgence in popularity.
The majority of creams and lotions are a blend of water and oil, as much as 70% of which is water. The oil that is used is normally a cheap petroleum derivative named paraffinum liquidum which provides no benefit to the skin. In the natural and organic skincare market the oils used should be more beneficial plant oils, in either an emulsion with plain water or a floral water. In order to mix these two components emulsifiers and thickeners are used, plus preservatives must be used due to the presence of water which can breed bacteria. Pure oils blends do not require these additives; instead each ingredient is used to bring benefits to your skin.
Our skin contains a sebum layer, made of natural oils. It forms a protective waterproof barrier for our skin. A water-based moisturiser can not penetrate this layer, instead it sits on top of the skin plumping the top layer of cells with water. Alternatively some moisturisers contain ethyl alcohol or ethanol which breaks down this sebum layer so that their ingredients can penetrate.
As oil blends contain no water, their composition is quickly absorbed, taking their wonderful skin benefiting nutrients with them.
