How can I remove wrinkles I got from Retin-A? I've used it on my eyes for about a week and the wrinkles are terrible.

Retin-A is not meant to be put right on the thin skin of the eyes, and certainly not daily for 4 days to start out.  There are many good eye creams that have retinol in them that can help with wrinkles without causing the issues you are having now (I'd recommend ZO's Hydrafirm).  You are not having an allergic reaction so I don't think steroid cream will help.  The redness and irritation is what Retin A does until the skin gets used to it; this is typical and "normal."  Do not put Retin A by or on the tissue of your eyes again.  The skin will return to normal by simply avoiding it there. 

Your eyelids should return to normal once the skin settles down. They appear dry, slightly swollen, and irritated and this can lead to rolled, wrinkled skin. I see this often in patients with allergic dermatitis of the eyelids. I agree with using steroids and a gentle moisterizure and giving things plenty of time to recover. Best of luck.
