Can a Botox browlift cause puffy upper eyelids (fluid retention)?

Thank you for your question and your concern. Properly injected Botox will not cause puffiness of the upper eyelid. However, if not done properly it can seep into the upper lid causing ptosis (droopiness) and that could be associated with some puffiness due to limitation of lid movement. That is why it is so important to have your treatments be performed by a qualified, board certified specialist.

Thank you for your question Minna2442. I understand your concern. Botox
is a purified protein used to address wrinkles associated with facial
expression. What you are referring to occurs under the eyes, not above the eyes where Botox is placed for a brow lift. This is a different part of the same muscle. Please consult with a doctor for specific recommendations. Good luck!

A Botox brow lift can cause upper eyelid or eyebrow drooping
(called ptosis) if not injected correctly. 
Done properly by a core specialist, an experienced Board Certified
Dermatologist.  Botox will not cause
puffy eyelids or the appearance of fluid retention.  Botox usually causes a 1-2 mm eyebrow lift.
