Non-volatile, non-fragrant plant kernel oil whose high saturated fat content has emollient properties for skin.
Coconut oil is a rich source of medium-chain fatty acids, also known as medium-chain triglycerides. Used by itself as a moisturizer, coconut oil’s effectiveness is similar to that of mineral oil.
Oral consumption of virgin coconut oil has been shown to increase the antioxidant content of skin compared to olive and sunflower oils.
Contrary to claims, coconut oil does not provide sufficient sun protection for skin. Research has shown it only screens about 20% of UV light before it can damage skin, which means 80% still gets through. Therefore, skipping regular, broad spectrum sunscreen in favor of coconut oil is putting your skin at risk for early signs of aging and other undesirable effects.
