Britney Spears has revealed a Botox treatment left one of her eyelids visibly drooping for four weeks and is now warning fans to be 'careful' with cosmetic procedures. In an Instagram video, the 44-year-old singer described the experience as 'so embarrassing' and claimed an injector had put so much Botox near her left eye that it caused the eyelid to drop.
Spears did not identify the practitioner or provide independent medical evidence about what caused the drooping. But her account has drawn attention because the problem she described — temporary eyelid or brow drooping, medically known as ptosis — is a recognised potential complication of botulinum toxin injections. The US Food and Drug Administration lists eyelid and brow drooping among reported adverse effects of Botox Cosmetic.
