Britney Spears has opened up about her recent experience with Botox Britney Spears/X

Britney Spears has opened up about a Botox experience that left her with a noticeably drooping left eyelid, saying the effect lasted for four weeks. The pop star shared the candid update on Instagram, showing followers what happened to her eye and turning a personal beauty mishap into a warning for anyone considering cosmetic injections.

The Oops!... I Did It Again singer said her eye was only recently beginning to return to normal after the treatment. The experience clearly left her unhappy with the result as it was visible for weeks.

Britney Spears Warns Fans About Botox

Britney Spears shared an Instagram video captioned: 'You can't trust anyone !!!' She demonstrated the effect of her Botox by pulling down the skin around her eyes as she explained what had happened.

'It's really bad because he put so much Botox in this left eye that it drew down like that,' Spears said. She explained that it was 'just now starting to raise up and be normal again' before admitting: 'It's so embarrassing.'

The singer then switched from describing her own experience to warning other women to be cautious.

'Girls, you have to be careful,' she said. 'If you do Botox with these people and these doctors, they can really f*** your eyes up.'

Spears said her eye remained drooped for around four weeks. She did not name the doctor or provide further details about where or when the procedure took place.

She also used the video to make a broader point about cosmetic procedures and personal choice. 'Be careful with these people,' she said, claiming that some may try to change a person's face without considering the consequences.

Spears ended the video by saying: 'Be careful with your bodies because it's yours and you own it.'

Botox Side-Effects You Should Know About

Botox may be a familiar part of the beauty world, but it is still a medical treatment and does come with potential side-effects. The treatment uses botulinum toxin to temporarily reduce muscle activity, which is why it can soften the appearance of certain facial lines.

The US Food and Drug Administration (FDA) lists eyelid ptosis, or drooping of the upper eyelid, as a reported adverse reaction to Botox cosmetic. According to the FDA's prescribing information, eyelid ptosis occurred in 3% of patients treated for frown lines between the eyebrows, while eyelid swelling was reported in 1% of those treated for crow's feet around the eyes.

Other reported effects involving the eyes include eyelid swelling, dry eyes, blurred vision and double vision.

That makes Spears' description of a drooping eye a recognised potential complication, although her personal account alone cannot establish exactly what caused her eyelid to droop.

Britney Spears' Legacy Goes Back Decades

For Spears, beauty has been part of her public image since she rose to fame on the pop scene in the late 1990s. As one of the defining stars of the late 1990s and early 2000s, Spears became a major fashion influence of the era, from her playful schoolgirl-inspired looks to glittering stage costumes and glamorous red-carpet outfits.

But Spears' latest message is less about maintaining a picture-perfect image and more about having control over her own body. After showing fans the result of a treatment she says went wrong, she urged them to be careful and remember that their bodies belong to them.

For a pop icon whose appearance has been watched and discussed for decades, that message feels particularly personal — and serves as a reminder that even popular beauty treatments can have unwanted consequences.
