Can Botox or filler correct upper eyelid ptosis?

Need photo of your eyes to give you more accurate answer. Botox is not effective. Upper eyelid filler may camouflage the ptosis at best.

Hi, thank you for the inquiry. Its difficult to comment about your situation without photographs, but as you don't want to opt for surgery then filler can help to uplift the upper eyelid to some extent. Botox won't be of much help to raise eyelid but by raising eyebrow it can give better look. I would recommend you to consult a professional injector and ptosis surgeon.

It's hard to comment with seeing a photo or evaluating you in person. In general, neuromodulators like Botox and Dysport can raise the eyebrows and gives the eyes are more open look. Fillers can also raise the brows my correcting volume loss. Usually, however, eyelid ptosis is best treated with surgery, not Botox or fillers. 

Hi - thank you for the question! Unfortunately ptosis cannot be corrected with wrinkle relaxers (Botox/Dysport/Xeomin) or filler. I cannot comment on your specific situation without a photo.
Subtle changes in brow position with wrinkle relaxers can improve the perceived appearance of lid symmetry. The more of your eyelid platform (place where you apply eyeshadow) is seen, the more “droopy” your eyelid appears. If you pull up on the eyebrow on the LESS droopy side & like this appearance, Botox may possibly help.
I recommend seeing your ptosis surgeon or someone very experienced with ptosis surgery.

Nothing short of another operation will correct the residual asymmetry. However this is easier said than done. The fact that you have a minor asymmetry after your first operation is testament to the fact that this is a delicate operation where, in my experience, it is not always possible to get the two upper lids perfectly symmetrical... it may be best to cut your losses and live with it. If you find you can’t, at least you will approach any further intervention with your eyes open!

Botox is not going to help with your eyelid ptosis, but if it's injected into the eyebrow depressors, it may make your eyes look more open. Good luck from New York City

Botox or Filler will not help with eyelid ptosis.  A minor revision is all that is needed for correction.  Ask your surgeon for his opinion.
