What a lip flip actually does
A lip flip is 4 to 8 units of Botox injected into the orbicularis oris, the muscle that runs along your upper lip border. The Botox relaxes that muscle just enough for the lip to roll slightly outward, showing a bit more of the pink vermillion. No volume is added. The lip doesn't get bigger; it just stops curling inward when you smile.
The whole thing takes 5 to 10 minutes. No downtime. Results start appearing in 3 to 5 days and peak around 2 weeks.
What lip filler does
Lip filler is a hyaluronic acid gel (Juvederm Ultra, Juvederm Volbella, Restylane Kysse, or RHA 2 are the most common) injected directly into the lip tissue. Unlike a lip flip, filler physically adds volume. Your provider can build shape, define the border, fix asymmetry, and create fullness in both the upper and lower lip.
Appointments run 15 to 30 minutes. Results are immediate, though swelling means the final look won't settle for about 2 weeks. (The day-two swelling can be alarming if nobody warns you. It goes down.) A 2020 study in Aesthetic Surgery Journal (n=210) found patient satisfaction with HA lip fillers stayed above 85 percent at 6 months.
Side-by-side comparison
| Factor | Lip flip (Botox) | Lip filler (HA) |
|---|---|---|
| How it works | Relaxes upper lip muscle so lip rolls outward | Adds hyaluronic acid gel for physical volume |
| Cost per session | $50 to $150 | $500 to $1,000 per syringe |
| Units / product | 4 to 8 units of Botox | 0.5 to 2 mL of HA filler |
| Results visible | 3 to 5 days (peak at 2 weeks) | Immediately (settles in 2 weeks) |
| Duration | 2 to 3 months | 6 to 12 months |
| Reversible | Wears off naturally | Yes, with hyaluronidase |
| Pain level | Minimal (2 to 4 small injections) | Mild to moderate (topical numbing used) |
| Best for | Subtle enhancement, gummy smile correction | Adding volume, reshaping, symmetry correction |
Who should get a lip flip
The lip flip is for people who want something subtle. Maybe you're trying lip enhancement for the first time and don't want to commit to filler. Maybe you have a gummy smile you'd like to tone down without adding volume. Maybe you just don't want to spend $700 right now.
The trade-off: results are modest, it only affects the upper lip, and you'll be rebooking every 2 to 3 months. That cycle gets a little tedious.
Who should get lip filler
Filler is the move if you want actual volume. It works on both upper and lower lips, lets your provider sculpt the shape, and lasts 6 to 12 months. We see a lot of first-time patients in our directory starting with a conservative half syringe (0.5 mL) of something like Restylane Kysse. You can always add more at a follow-up two weeks later, but you can't take away overfilling without dissolving it.
A lip flip is a $100 test drive. If you're not sure you want volume, start there. But understand it won't tell you what filler feels like — they're fundamentally different procedures solving different problems.
Can you combine them?
Yes. And plenty of providers recommend it. The lip flip gives you that upper lip rollout from the Botox while the filler adds the actual volume underneath. Both can be done in the same appointment. Combined cost runs $550 to $1,100.
This combo is especially popular for patients whose upper lip tends to disappear when they smile. The Botox prevents the lip from tucking under while the filler keeps it full.
Cost breakdown
| Treatment | Cost per session | Annual cost (maintenance) |
|---|---|---|
| Lip flip only | $50 to $150 | $200 to $750 (4 to 5 sessions) |
| Lip filler (1 syringe) | $500 to $1,000 | $500 to $1,500 (1 to 2 sessions) |
| Lip flip + filler combo | $550 to $1,100 | $750 to $2,000 |
