reccomended glycolic peels

Im looking to buy one of those at home glycolic acid peels and looking for the best brand?

lacking in zinc

I have moderate acne now, and had a saliva test done and a nutritionalist and he said I was extremly low in zinc! Do you think this could be causing my acne?

My red marks

So Ive had severe, dark red marks all over my face for about two years now with no signs of improvement and was looking at glycolic acid. My derm said the red marks were "vascular" whatever that means?? So would the glycolic acid still help me?
