Oleic acid
I have read oleic acid is detrimental to the skin barrier. I went through a study which showed olive oil is also bad as it includes oleic acid. As far as I know, oleic acid is converted to triglyceride. So I assume only free oleic acids present in oil may harm tha skin. Good quality olive oil has very low amount of free oleic acid, less than 0.8% in 100g extra virgin oil. What’s your opinion? Do you have evidences which show oils high in oleic acid are bad for skin?
I have also read proper oleic to linoleic ratio of oil should be used in skincare i.e. small amount of oleic acid to high amount of linoleic acid (as it is beneficial for the skin). Do you know what ratio is that?
As linoleic acid is also not present in oils, oils high in linoleic acid are beneficial to the skin?
