Evidence supporting the use of: Fractionated vegetable oil
For the health condition: Skin Care (general)
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Fractionated vegetable oil, particularly fractionated coconut oil (also known as medium-chain triglycerides or MCT oil), is commonly used in skin care products. There is scientific validation for its use in general skin care, though the evidence is moderate rather than robust. Fractionated vegetable oil is valued for its unique properties: it is lightweight, non-greasy, and has a long shelf life. It is composed mainly of caprylic and capric triglycerides, which are stable and less likely to oxidize compared to whole oils.
Several studies and dermatological reviews highlight that fractionated oils can effectively function as emollients, helping to soften and smooth the skin by forming a protective barrier that reduces water loss. This property supports skin hydration and can improve skin texture. Furthermore, fractionated oils are less likely to clog pores than some other oils, making them suitable for a range of skin types, including those prone to acne. However, fractionated oils lack the full spectrum of fatty acids and nutrients found in unrefined oils, which may limit their reparative or antioxidant effects.
In summary, the use of fractionated vegetable oil in general skin care is supported by scientific principles of emolliency and occlusion, as well as by its safety profile and stability. However, high-quality clinical studies specifically examining its efficacy in treating or preventing skin conditions are limited, so the overall evidence is rated as moderate (3/5).
