Eyelid ptosis is a rare complication of Botox injections that occurs when botox is injected over the brow and that affects the palpebral muscle. This is often due to improper injection placement or massaging after the botox, or vigorous sports has been doing after injection. The treatment for that is time and reversible after botox has lost its efficacy which takes around 3-6 months. I did not head nor read any permanent case.
Thank you for your question. Any time Botox is injected, there is a small risk of it drifting and affecting other muscle groups. When Botox is injected between the eyebrows, it can rarely drift and affect the muscles that control the upper eyelid or the movement of the eye itself, most often due to improper injection placement. The results of Botox are temporary, and gradually fade over the course of 3-4 months. I would recommend seeing an experienced cosmetic dermatologist or plastic surgeon for your treatments. Best of luck!
