Quick Answer
The lip flip is a technique that uses a very small dose of botulinum toxin A injected into the orbicularis oris muscle above the upper lip to cause the lip to gently "roll" outward without actually enlarging it. It is ideal for those seeking natural-looking fullness without filler, who want to reduce a thin upper lip or the amount of gum visible when smiling. Total dose is 4–6 units, effect lasts 6–12 weeks — much shorter than filler but far more natural-looking. At Virtuana Clinic, both options can be evaluated together during your consultation.
What Is a Lip Flip? The Anatomical Basis of the Technique
The lip flip — also referred to as "lip eversion" — is a minimally invasive aesthetic procedure based on the highly precise, low-dose application of botulinum toxin A to certain fibers of the orbicularis oris muscle at the upper lip border. First described in the 1990s, it has spread to a much wider patient base in recent years as demand for natural lip aesthetics has grown, partly fuelled by social media.
The orbicularis oris is a circular muscle that constricts and purses the lips. When the portion of this muscle close to the vermilion border of the upper lip is partially relaxed, the lip gently rotates outward — the word "flip" describes exactly this rotation. The result makes the lip appear fuller, but achieves this not by adding real volume, rather by making existing volume more visible.
At Virtuana Clinic, our lip flip protocol accounts for the individual variability of each patient's facial anatomy to personalise injection points and dose.
What Problems Does a Lip Flip Solve?
A lip flip is not appropriate for every aesthetic concern. The clinical situations it genuinely addresses are:
- Thin upper lip: If the upper lip appears thin because the vermilion border is hidden inside, the flip rolls this portion outward and increases the appearance of fullness.
- Gummy smile during smiling: Excessive gum exposure (>3–4 mm) during a smile can be significantly reduced by weakening the orbicularis oris and levator labii muscles.
- "Lip rolling inward": In some people, particularly during speech or laughter, the upper lip rolls inward and the vermilion becomes invisible; the lip flip corrects this behaviour, providing a more visible lip.
- Fine vertical lines around the lip: Reducing orbicularis oris activity also partially slows the formation of perioral wrinkles.
Lip Flip vs. Lip Filler: A Comprehensive Comparison
The most frequently asked question is what the difference is between a lip flip and lip filler. These two procedures involve different mechanisms, yield different results, and appeal to different patient profiles; one is not a true substitute for the other.
| Feature | Lip Flip (Botox) | Lip Filler (HA) |
|---|---|---|
| Mechanism | Muscle relaxation → lip rolls outward | Direct volume addition with hyaluronic acid |
| Volume increase | None (optical effect) | True volume increase |
| Duration of effect | 6–12 weeks | 9–18 months |
| Procedure time | 5–10 minutes | 20–40 minutes |
| Pain/discomfort | Minimal (fine needle) | Moderate (tolerable with topical anaesthetic) |
| Recovery time | 1–3 days mild bruising/swelling | 3–7 days swelling, bruising |
| Reversibility | Resolves on its own | Dissolvable with hyaluronidase |
| Ideal patient profile | Natural look, thin upper lip, gummy smile | Noticeable volume increase, proportion correction |
Lip Flip Application: Step-by-Step Protocol
The lip flip procedure performed at Virtuana Clinic consists of the following stages:
- Consultation and facial analysis: Lip anatomy, proportions (upper-to-lower lip, Phi ratio), smile analysis, and patient expectations are assessed. Whether a lip flip alone or in combination with filler is more appropriate is discussed.
- Photography: Pre-treatment standardised photographs are taken — at least three positions: neutral, smiling, and in motion.
- Anaesthesia: Topical anaesthetic cream is applied for 10–15 minutes. As the pain of botulinum toxin injections is minimal, additional infiltration anaesthesia is generally not required.
- Injection: A total of 4–6 units of botulinum toxin A (brand-independent) is applied via a very fine needle (30–32G) to multiple points close to the upper lip vermilion border. If Cupid's bow symmetry or Gummy Smile is the target, additional injection points may be evaluated.
- Cold compress and final assessment: Cold pressure is applied for 2–3 minutes after injection, and the treated area is reviewed.
Recovery Process After a Lip Flip
The lip flip is a procedure favoured for its low downtime. Nonetheless, some temporary side effects are normal following injection:
- First 24–48 hours: Minor bruising and mild swelling at the injection points may occur. Ice application reduces swelling.
- Days 2–5: The effect of botulinum toxin begins; a slight change in sensation or sense of muscle weakness in the lip may be felt.
- Days 7–14: Full effect becomes apparent. The lip visibly rolls outward and the upper vermilion looks fuller.
- Weeks 6–12: The effect gradually recedes and muscle activity returns to normal. If re-injection is desired, it can be planned during this period.
During the first few days, a slight reduction in lip muscle strength may be noticeable when drinking from a glass; this is temporary and adaptation occurs within a few days. A temporary difference may be noticed when kissing or using a straw.
Ideal Patient Profile for a Lip Flip
A lip flip is an ideal option for patients with the following characteristics:
- Those who wish to enhance a thin upper lip but are not ready for or do not want filler
- Patients with excessive gum exposure when smiling (Gummy Smile)
- Those who have previously had lip filler and are now seeking a more natural supplemental boost
- Younger patients who want to "try out" a result and have not yet decided on a permanent change
- Those wishing to reduce fine vertical lines beginning to form around the lip
A lip flip is not recommended for: very thin or very small lips (if there is no volume, the flip has limited effect), lower lip application (risk of swallowing and speech complications), active infection in the lip area, and patients with contraindications to botulinum toxin.
Lip Flip for Gummy Smile Treatment
Gummy smile (gingival smile) is defined as the upper gums being visible by more than 3–4 mm during a smile. It can have multiple causes; however, hyperactivity of the muscles that lift the upper lip (levator labii superioris, levator labii alaeque nasi) is the most commonly encountered aetiology. Applying botulinum toxin to this muscle group reduces the amount the lip is pulled upward when smiling and dramatically decreases gum visibility.
The combination protocol used for gummy smile treatment at Virtuana Clinic may include levator injection alongside the lip flip, and results generally appear very natural and harmonious. A single session can provide 4–6 months of relief.
Lip Flip Complications and Risk Management
In skilled hands, the lip flip is an extremely safe procedure; however, practitioner experience is critical for this technique. Possible complications and their management:
- Excessive relaxation: With a very high dose or incorrect muscle group targeting, a weak, "drooping" lip appearance may result. This is temporary and resolves within 6–12 weeks. For this reason, starting with a low dose and adding if needed ("less is more") is the gold standard for lip flips.
- Symmetry disturbance: May arise from asymmetric application of injection points or anatomical muscle asymmetry; it can be corrected with minor adjustments at the day-14 evaluation.
- Changes in speech and expression: At very high doses, the lip-pursing movement (kissing, whistling) may be temporarily impaired. At the standard 4–6 unit dose, this risk is minimal.
- Bruising: Can develop from contact with superficial small vessels; resolves on its own within 5–10 days. Risk is reduced with a fine needle and experienced practitioner.
Combining Lip Flip and Lip Filler
In some patients, the best result is achieved by combining both a lip flip and lip filler. With this combination: filler provides real volume while the lip flip increases vermilion visibility; a more natural effect is created that reduces the "overfilled" or "artificial" appearance of filler; and if Gummy Smile is present, the lip flip serves that function simultaneously.
In combined applications, two options exist: both botox and filler in the same session (requires a highly experienced practitioner), or lip flip first, followed by filler two weeks later. The second option is preferred at Virtuana Clinic as it allows the filler volume to be optimised after observing how the muscle behaves.
