A lip flip is temporary, lasting only a few months. However, lip fillers and implants are permanent, so if you don’t like the results there’s not much you can do about it other than have surgery again. Botulinum toxin injections can help create a softer, more youthful facial appearance in general, but Botox lip flips are a procedure growing in popularity recently because it’s a safe way to achieve fuller lips without committing to permanent lip augmentation results.
