Botox Injection Caused By Case Analysis and Treatment Experience Sharing of Eyelid Edema.

Botulinum toxin is a noninvasive cosmetic procedure that relaxes facial expression muscles to mitigate the development of dynamic wrinkles. It inhibits nerve signals, temporarily paralyzes muscle activity, and reduces muscle contractions, thereby smoothing the skin and minimizing wrinkles. Botox injection for wrinkle reduction has become a widely used antiaging treatment due to its rapid effects, noninvasive nature, and short recovery time. Common adverse effects include local swelling, bruising, and ptosis, while eyelid oedema occurs less frequently. This study presents a case of allergic conjunctivitis and eyelid oedema occurring several days following botulinum toxin injection for wrinkle reduction.
