What Is a Lip Flip?
A lip flip is a minimally invasive cosmetic procedure that uses a small amount of Botox to enhance the upper lip’s appearance by relaxing the muscles around the mouth. Unlike traditional lip fillers that add volume to the lips, a lip flip creates the illusion of a fuller lip by subtly “flipping” the upper lip outward. This gives the lip a more defined, pouty look without actually increasing its size.
The treatment has surged in popularity, especially among people seeking a natural enhancement without the commitment or cost of dermal fillers. It’s ideal for individuals with a thin upper lip or those whose top lip seems to disappear when they smile. A lip flip can also soften vertical lip lines and create a more balanced facial expression.
Botox used in this context is injected into the orbicularis oris muscle, which controls the movement of the lips. When this muscle is relaxed, the upper lip gently rolls upward, exposing more of the pink part of the lip. This change is subtle yet noticeable, offering a refined look that’s particularly photogenic.
Lip Flip Procedure Explained
Preparation and Consultation
Before undergoing a lip flip, a professional consultation is essential. The injector—typically a board-certified dermatologist, cosmetic nurse, or plastic surgeon—will assess your facial anatomy, lip shape, and aesthetic goals. During this consultation, you’ll also discuss any medical history that may affect the treatment, such as allergies or muscle disorders.
There’s minimal prep involved. Patients are generally advised to avoid alcohol, blood thinners, and certain supplements (like fish oil or vitamin E) a day or two before the procedure to reduce the risk of bruising.
The Botox Injection Process
The procedure itself is quick and virtually painless. Using a fine needle, the practitioner injects a few units of Botox (usually between 4–8 units) into the area just above the upper lip. The injections target specific points of the orbicularis oris muscle to achieve an even and natural flip.
The entire process takes less than 15 minutes, and patients can typically return to their daily activities immediately after. There’s no need for anesthesia, though some clinics offer numbing cream if requested.
Immediate Post-Procedure Care
After the injections, there may be slight swelling or redness, but these symptoms usually subside within an hour or two. Patients are advised to avoid strenuous exercise, excessive heat (like saunas or hot yoga), and touching or massaging the area for the rest of the day.
You might not see changes immediately. It usually takes 3 to 5 days to notice the initial effects, with full results visible within 10 to 14 days. It’s a gradual process that unfolds subtly but beautifully.
Lip Flip Before and After Results
Changes in Lip Shape and Projection
The “before and after” of a lip flip isn’t as dramatic as with dermal fillers, but it’s certainly noticeable—especially in motion or during a smile. In the “before” phase, the upper lip may appear flat or vanish when smiling. After the procedure, the lip gently curls outward, revealing more of the pink lip and creating a fuller, more symmetrical appearance.
This transformation is especially flattering for people whose lips appear thin or compressed. It enhances the smile and adds character to the face without changing its natural proportions.
Timeline of Results
While subtle at first, results gradually improve over one to two weeks. Most patients report peak satisfaction around day 10. Unlike fillers, which add volume instantly, Botox works by weakening muscle movement over time.
The effects typically last 6 to 8 weeks, after which the muscle regains full function. Because the results are temporary, it offers a low-commitment option for people testing the waters of cosmetic enhancement.
Photos and Common Transformations
In clinical and promotional images, the difference between lip flip before and after is clear. The upper lip sits higher and projects outward slightly more. The Cupid’s bow may appear more defined, and the smile looks more expressive. These subtle enhancements can dramatically affect how youthful and refreshed someone appears.
It’s also worth noting that the results vary depending on lip anatomy, the number of units used, and the skill of the injector. That’s why choosing an experienced provider is crucial.
Side Effects and Risks to Consider
Temporary Bruising or Swelling
Minor side effects are common but usually short-lived. Bruising at the injection site is the most frequently reported issue, though it typically resolves within 2–3 days. Swelling, redness, or tenderness may also occur, but these symptoms are mild and manageable with cold compresses and rest.
Speech and Lip Movement
Because the lip flip involves relaxing the muscles that control lip movement, some patients notice temporary changes in speech or difficulty drinking from straws. These effects are uncommon and generally fade as the body adjusts to the Botox.
If too much Botox is used, it can overly relax the muscle, causing the lip to droop or the smile to appear stiff. This is why precise dosage and proper technique are vital.
How Long Side Effects Last
Most side effects resolve quickly—within a few days. Rarely, slight asymmetry or overcorrection can last for several weeks. However, since Botox is temporary, even an imperfect result will naturally fade within 6–8 weeks, and adjustments can be made during future visits.
Maintaining and Enhancing Results
How Long Results Last
Unlike dermal fillers that last up to a year, a lip flip generally lasts between 6 and 8 weeks. Some patients report results lasting slightly longer with repeat treatments, as the muscles become more responsive to the Botox. Because of this short duration, many patients choose to schedule routine maintenance every 2 to 3 months.
This also provides flexibility. If you’re unsure about committing to lip augmentation, the lip flip offers a reversible option that you can refine over time.
Follow-Up Appointments
Most providers recommend a follow-up visit two weeks after the first session. This allows them to evaluate the results and touch up any unevenness if needed. If you’re happy with the outcome, you can book your next session on a predictable cycle.
Some clinics offer bundled packages for lip flips to make maintenance more affordable and convenient.
Combining Lip Flip with Other Treatments
Many patients combine a lip flip with lip fillers to enhance both shape and volume. This duo can deliver a stunning yet natural look—where the filler adds fullness and the flip defines the shape. Others pair it with a Botox brow lift or cheek contouring for a harmonious, youthful appearance.
Because the lip area is central to facial expression, small enhancements can yield big improvements in overall aesthetics.
