The “lip flip” has become one of the most buzzed-about non-surgical cosmetic treatments — especially for those who want a subtle, natural-looking enhancement without going the full filler route.
But what exactly is a Botox lip flip? And how long do the results really last?
Here’s what you need to know if you’re considering this quick, minimally invasive treatment.
What Is a Botox Lip Flip?
A Botox lip flip is a cosmetic procedure where small amounts of Botox are injected into the muscles just above your upper lip — specifically, the orbicularis oris muscle.
Rather than adding volume (like dermal fillers do), Botox relaxes the muscles around the mouth, causing the upper lip to gently “flip” outward, creating the appearance of:
- A fuller, more defined lip line
- More visible upper lip when smiling
- A softer, natural enhancement — especially in people with a “gummy” smile
It’s subtle, quick, and often preferred by first-timers or those who want a low-commitment option.
How Does a Lip Flip Differ from Lip Filler?
While both are lip enhancements, they work very differently:
| Feature | Botox Lip Flip | Lip Filler |
|---|---|---|
| Product used | Botox (neuromodulator) | Hyaluronic acid-based filler |
| Effect | Relaxes muscles to subtly flip upper lip | Adds physical volume to lips |
| Volume added | None | Yes — lips become plumper |
| Duration | ~6–8 weeks | ~6–12 months |
| Cost | Lower ($50–$150) | Higher ($400–$800 per session) |
Some people even choose to combine both for enhanced results.
How Long Does a Botox Lip Flip Last?
In the U.S., most lip flips are performed by licensed medical professionals such as dermatologists, plastic surgeons, or certified injectors in med spas. Most Botox lip flips last around 6 to 8 weeks.
That’s significantly shorter than traditional Botox injections for the forehead or crow’s feet, which usually last 3–4 months. Why the difference?
- The muscle around the mouth is highly active, so it metabolizes Botox faster
- A lip flip uses very small doses, so the effect fades more quickly
- It’s meant to be subtle and temporary — perfect for trying it out
Want longer-lasting results? A second treatment after your first wears off may help extend future duration.
A lip flip enhances your upper lip in a subtle, natural way — but it’s just one of many ways Botox can be used. Here’s a full guide to how long Botox lasts in other areas
What Is the Procedure Like?
The treatment is quick — usually under 10 minutes.
Here’s what to expect:
- Your injector will assess your lips and smile
- A few small Botox injections will be placed just above the upper lip
- You can return to normal activities immediately — no downtime needed
Results typically appear within 3 to 7 days, with full results showing by day 10.
Are There Any Side Effects?
Side effects are usually minimal and temporary. You may notice:
- Mild swelling at injection sites
- Temporary numbness or tightness when speaking or drinking
- Slight difficulty using a straw (for the first few days)
More serious side effects are rare but possible if the injections are improperly placed — that’s why working with a qualified provider is essential.
Who’s a Good Candidate for a Lip Flip?
You may be a good fit if:
- You want a subtle enhancement
- You feel your upper lip disappears when you smile
- You’re curious about lip filler but want to start smaller
- You have a mild gummy smile and want to reduce upper gum visibility
Not ideal if:
- You want dramatic volume
- You already have dermal filler and don’t want over-enhancement
- You’re allergic to Botox or neuromodulators
Final Thoughts: A Simple, Subtle Enhancement
The Botox lip flip is a quick, affordable way to enhance your upper lip — without the commitment or volume of fillers. It’s perfect for first-timers or anyone seeking a more balanced smile.
And while it doesn’t last as long as other Botox treatments, it offers a low-pressure intro to cosmetic enhancement with results that speak for themselves.
