A lip flip with botulinum toxin is a subtle, non-surgical treatment that makes the upper lip appear fuller, without the use of fillers. At Xavier Clinics in Amsterdam, we use this technique for people who want to give their lips a little more definition, with a natural look.
Unlike lip fillers, a lip flip doesn't add volume. The treatment relaxes specific muscles around the upper lip, causing it to tilt slightly outward. The result: a softer, more feminine lip shape and improved visibility of the upper lip, especially when smiling.
What exactly is a lip flip?
A lip flip involves a small amount botulinum toxin Injected into the orbicularis oris muscle just above the upper lip. This muscle normally pulls the lip inward. By temporarily relaxing it, the upper lip gently rolls outward.
This ensures:
- More visible upper lip without extra volume
- A softer transition between skin and lip
- Less 'disappearing' upper lip when smiling
The treatment is quick, safe and requires no recovery time.
Who is a lip flip suitable for?
A lip flip is especially suitable if you:
- Have a thin upper lip, especially when smiling
- Do not want to add any (or little) volume with fillers
- A natural improvement seeks
- Are you afraid of lips that are too full or unnatural?
If you have a lack of volume or asymmetry in the lips, a lip filler Or a combination of lip flip and filler might be more appropriate. During a consultation at Xavier Clinics, we'll discuss together what suits your face best.
Lip flip versus lip fillers
A frequently asked question is what the difference is between a lip flip and lip fillers:
Lip flip with botulinum toxin
- No volume, but optical magnification
- Subtle and natural effect
- Ideal for a 'disappearing' upper lip
Lip fillers (hyaluronic acid)
- Actually add volume
- More shape and contour
- Results are visible for longer
Both treatments have their own indications and can reinforce each other.
What is the treatment like?
- Intake and analysis of the lips and facial expressions
- Explanation of the expected result
- Injection of small amounts of botulinum toxin
The treatment takes on average 5–15 minutes. The injections are administered with a very fine needle and are usually well tolerated.
Result and durability
The effect of a lip flip is subtle but visible.
- Onset of effect: after 3–5 days
- Optimal result: after approximately 10–14 days
- Shelf life: average 3–4 months
Because muscle activity returns gradually, the treatment can be safely repeated.
