A lip flip is a relatively new cosmetic procedure that reportedly gives a person fuller lips with one quick and straightforward treatment. People also refer to it as a lip injection. A lip flip involves injecting the neurotoxin Botox into the upper lip.
This article explores the lip flip procedure, its side effects and complications, and the things individuals should consider before having the treatment. It also covers how people can find a qualified provider.

What is a lip flip?

A lip flip is a nonsurgical method of creating a fuller lip. A doctor injects botulinum toxin A, popularly known as Botox, into the upper lip to create an illusion of a larger lip. It relaxes the muscles above the lip, resulting in the upper lip “flipping” slightly upward. Although the procedure makes the lip look more prominent, it does not increase the size of the lip itself.
Lip flips may be particularly beneficial for individuals who have smiles that expose much of their gums. Following a lip flip, less gum shows when the individual smiles because the upper lip elevates less.

How it works

A lip flip involves injecting a type of abobotulinumtoxin A, such as Botox, Dysport, or Jeuveau, into the top lip. The goal is to relax the orbicularis oris muscle, which helps form and shape the lips. The injection encourages the top lip to relax and “flip” outwards, giving the subtle illusion of a fuller lip.
The lip flip is a quick procedure, taking less than 2 minutes. Because of this, it can be a suitable option for those wary about more invasive surgeries.

Lip flip vs. dermal fillers

Dermal fillers are gels that cosmetic doctors inject into the skin to restore volume, smooth lines, wrinkles, or enhance facial contours. They are second Trusted Source only to botulinum toxin injections as the most common nonsurgical cosmetic procedures.
One popular type of dermal filler is hyaluronic acid, a substance that exists naturally in the body. Hyaluronic acid can help restore volume and moisture in the skin. When doctors inject it directly into the lips, it creates definition and boosts lip volume, resulting in a fuller lip.
While dermal fillers increase lip size, a lip flip only creates the illusion of a larger lip without adding volume.
Lip flips are less invasive and expensive than dermal fillers. However, they have a shorter effect than dermal fillers, which last between 6 and 18 months.
Another difference is that it takes up to a week to see lip flip results, while dermal fillers show immediate results.

Recovery and results

Individuals should avoid exercising for the remainder of the day and avoid sleeping facedown for the night after a lip flip procedure. It is normal to have a small bump at the injection site for a few hours following treatment. Bruising may also occur.
Results appear over a few days. During this time, the orbicularis oris muscle relaxes, which allows the upper lip to lift and “flip.” People should see the full results about a week after treatment.
A lip flip lasts for about 2–3 months. It only lasts for a short duration because the upper lip muscle often moves, causing its effects to wear off. This short period might be due to the small dose involved.
