Natural oils are used extensively throughout the world as moisturizers but in spite of their growing popularity, there is surprisingly limited data on their efficacy and safety profile.

There are 5 generally agreed upon skin types in the skincare and cosmetics industries: normal, dry, oily, combination and sensitive.

Our skin is in a constant state of renewal, sloughing off old layers, and regenerating new ones. These new layers are generated from stem cells in the basal layer of the epidermis, and as time progresses, these cells gradually change into different types of cells on their pathway to the surface of the skin, or the “epidermis.”

The stratum corneum, the outermost layer of the epidermis (the epidermis is the outermost layer of the skin), is made up of skin cells and oils that sit together like bricks and mortar.
