It is generally not advisable to use fillers in the upper eyelids following a blepharoplasty. While blepharoplasty aims to remove excess skin and improve the appearance of the eyelids, fillers are typically used for adding volume, which may not be appropriate for this area. The eyelids are a very delicate and sensitive part of the face, and the introduction of fillers can lead to several significant risks, such as: Infection: The risk of infection is heightened due to the delicate nature of the eyelid tissue and its proximity to the eye. Vascular Complications: There is a possibility of the filler obstructing blood vessels in the eyelid area, which can lead to serious complications. Vision Problems: In rare cases, incorrect filler placement can result in vision impairment or even blindness. Asymmetry and Lump Formation: Uneven distribution of the filler can create an asymmetrical appearance or lumps, which can be difficult to correct.
