there’s actually some interesting stuff out there about acne possibly being linked to having too little omega-6s instead–the lipid profile of the sebum of people with acne is deficient in linoleic acid
can’t remember all the details but it affects keratinization as well as a lot of other stuff
the deficiency doesn’t seem to be systemic, just in production–eating enough n-6 but somehow not able to get it to the surface of the skin (though some people take borage oil orally and have a lot of success)
have heard good things about using high-linoleic oils (safflower etc) on acne-prone skin
