How long should a eyebrow lift last?

A true brow lift will last forever, but that does not mean you will not continue aging after having your brow lift. Tissues stretch, loose elasticity and will continue those changes after your procedure. You will always be ahead of where you would have been had you not had the brow lift. 
There are many different types of brow lifts to choose from, and what is right for you will depend on your individual needs, goals and anatomy.  
To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon.

Hello hollie cThey are usually permanent, I would advice schedule a consultation with aboard certified plastic surgeon.

It honestly depends on the type of lift you undergo, the degree of correction and several other factors related to genetics. On average, brow lifts last around 10 years depending on the factors previously mentioned. A proper brow lift will help alleviate signs of aging and produce a more youthful appearance. I recommend meeting with a board-certified plastic facial surgeon to discuss the treatment option best suited for your facial structure.
