A lip flip usually starts to show subtle changes in 2 to 5 days , with the full effect typically visible in about 1 to 2 weeks. Some people may notice results a bit sooner or later depending on how their body responds.

Quick Scoop

The lip flip works gradually because it uses a small amount of neuromodulator to relax the upper lip muscle, not to add volume right away. That’s why the “flipped” look tends to build over several days instead of appearing instantly.

What to expect

  • Day 1 to 3: Usually little visible change, though the muscle may start relaxing.
  • Day 3 to 5: More noticeable softening and slight outward roll of the upper lip may begin.
  • 1 to 2 weeks: Most people see the full result by this point.

Timing notes

Results can vary based on dosage, injection placement, and your own muscle response. If you’re comparing it with filler, a lip flip is generally subtler and temporary, while the final look is meant to be natural rather than dramatic.

Bottom line

If you just had a lip flip, give it up to 2 weeks before judging the final result. If the change feels uneven or you’re worried about the outcome, it’s best to check in with your injector.
