I've had some luck in reducing pore size and flakiness by using glycolic acid. You have to test out your tolerance slowly but I've been using glycolic acid pads and have seen a real difference. I read somewhere recently that someone else was using this for their seb derm and had good results. I seem to be ok with once a week so far with 10 percent. I've used 20 percent but I would recommend going very slowly with that to avoid a flare. Hope this helps someone....I think it's worth a shot, especially for reducing pore size. I have a noticeable difference.
