As you can see, coconut oil was clearly better than mineral oil in reducing AD score and water loss.
Coconut oil is strongly antibacterial, which, I believe, is the main reason it could reduce acne. Lauric acid (LA) is the main fatty acid in coconut oil and accounts for roughly 50% of all the fat. APs:以上引用自: http://www.acneeinstein.com/coconut-oil-acne/2009 study showed LA kills acne causing bacteria 15 times more effectively than benzoyl peroxide. Another study showed capric acid, another fatty acid in coconut oil, is also effective against P. Acnes bacteria – though weaker than lauric acid.
These studies clearly show that lauric acid is one of the best natural antibiotics against acne-causing bacteria.
Coconut oil contains several anti-inflammatory substances, including ferulic acid, p-coumaric acid, and other phenolic compounds.Ps:以上引用自: http://www.acneeinstein.com/coconut-oil-acne/Ferulic acid is used as an antioxidant in many high-end skin care products. There’s some evidence to show these can protect the skin.
Coconut oil is as effective and safe as mineral oil when used as a moisturizer for mild to moderate xerosis (dry skin) [45] and was shown in one study to reduce protein loss when used on hair .Ps:以上引用自: https://en.wikipedia.org/wiki/Coconut_oil
