Hydrogenated oil and bad oils(over fried vegetable oil) was the cause of my acne. Eliminated those from my diet I don’t get any acne. I can tell right away if I ate bad oils because the next day I will break out. When the body can’t process sugars or oils properly it will dump it out on your skin plugging up your pores(acne). As a teen I had terrible acne and looking back I can 110% relate it to bad over-fried oils or hydrogenated oils. Hydrogenated oils need to be banned forever. Still there is a lot of fast food places that use the artery clogging, acne producing oil.
Most cases acne is the body’s way of telling you that something is not being processed properly it and it is getting dumped out on the skin. Some might have smaller pores than others making them more prone to acne.
