I am trying to decide whether vit A or C is best to be applied topically to the skin (face) for dehydrated skin, fine lines and open pores. I have slightly oily skin but but I don't believe that has caused my open pores, I think they are just dehydrated or maybe I need more collagen... My skin sometimes feel tight or tingley so I think maybe it has got dry. I have started a course of Environ facials using Iontopheresis to penetrate the vit a & c products deeper, but don't know whether to buy an additional serum, and what is the most effective vitamin for my problem.. Can anyone help?
