Green coffee oil is obtained by cold pressing green (unroasted) coffee beans. Researchers from several universities in Brazil, the largest coffee producing country in the world, have shown that administration of green coffee oil to fibroblast cultures results in the upregulation of collagen, elastin, and glycosaminoglycans as well as growth factors, such as transforming growth-β1 (TGF-β1) and granulocyte-macrophage colony-stimulating factor (GM-CSF). In addition, results from the same research team demonstrated an increase in aquaporin levels due to green coffee oil treatment in keratinocyte cell cultures. Green coffee oil contains lipids that consist triacylglycerols, sterols, and tocopherols in addition to diterpenes, which have important pharmacological properties.
A great deal of interest in using coffee in skin care products stems from the effects of caffeine on skin biochemistry and physiology, in which case it has been shown to prevent accumulation of fat in the skin, act as a photo-protectant against UV radiation, and assist in drainage of lymphatic tissue.
Recent work focuses on the solar protection properties of green coffee oil and the oil fraction of spent coffee grounds. In sunscreen systems containing ethy-hexyl-methoxy-cinnamate, addition of green coffee oil provided an increase of 20% in sun protection factor (commonly known as SPF). Botanical oils, typically found in cosmetics, contain large amounts of unsaturated fatty acids, which are susceptible to lipid oxidation. Green coffee oil was found to improve efficacy of other botanical oils, probably due to increased protection of the oil from the elements.
