I have lost some weight and have developed an extra crease in my left eye. If I gain weight will the issue be corrected? (photo)

 Weight gain or loss does not affect the eyelids, since the fat there is non-insulin-dependent. If the small extra crease bothers  you,it should be surgically removed under local anesthesia

The fat in the eyelid is not affected by weight loss. Often we do note asymmetries in our eyes after we've lost some volume in our cheeks from the weight loss. If it really bothers you I would recommend keeping the weight off and seeing an oculoplastic specialist. Good luck.

Extra eyelid skin is not caused by your weight loss. Weight gain will not fix it. You will need surgical removal of this extra skin.
