a lip flip is a quick treatment that uses neuromodulators, such as botox, to relax the muscles in the upper lip, causing the lip to "flip" and gives the appearance of a fuller upper lip.
a tip for newbies:
a lip flip is a good option if you want a subtle change to your lips, or if you're not ready to commit to lip filler.
lip filler is a good option if you want to add more volume to your lips and it provides longer lasting results than a lip flip.
