A lip flip at InjectCo is $199. Most lip flips use about 4 to 6 units of Botox placed along the upper lip border, and results are temporary. A lip flip changes how the upper lip sits rather than adding volume, so it suits people who want a subtle change.

A lip flip at InjectCo is $199, and the price is the same at all nine Texas locations.
For lip flip treatment alongside Botox in other areas, those areas are priced by the unit. Botox $12 per unit, or $7.77 per unit with membership ($24.99/month). Your nurse injector will give you a total before anything is injected.
A lip flip is a small dose of Botox injected into the orbicularis oris, the ring of muscle around the mouth, just above the upper lip border. Relaxing those fibers lets the upper lip roll slightly outward, so more of it shows, especially when you smile.
It does not add volume. A 2026 prospective study used 3D imaging on 17 women and found a small increase in upper lip height with no change in lip volume at any point. Patients still reported high satisfaction, which says more about how subtle changes are perceived than about size.
The lip flip is an off-label use of Botox. The BOTOX Cosmetic prescribing information covers specific facial lines, and the lips aren’t among its treatment areas.
A lip flip may suit you if:
It’s probably not the right tool if you want noticeably fuller lips. That’s what filler does.
A 2025 systematic review in Archives of Dermatological Research found that lip flips typically use 4 to 6 units of Botox in the orbicularis oris. The 2026 study used 4 units, 2 on each side, placed just above the lip border.
Your nurse injector sets the dose after watching how your upper lip moves. More is not better here. Too much relaxation can make it harder to sip through a straw, whistle, or pronounce some sounds, so a conservative first dose is common. For how this compares with other areas, see Botox units by area.
The research gives a shorter and more specific answer than most clinic pages. In the 2026 study, upper lip height increased significantly at the 15-day check. By 30 days, the change was no longer statistically significant, and at 90 days lip height was back at baseline.
Two caveats matter. That study was small, with 17 participants, and it measured lip height with 3D imaging rather than asking how long people noticed a difference. The 2025 review summarized technique, dosing, and safety but did not report a duration in its abstract.
The practical takeaway: expect the effect to be at its clearest around two weeks and to fade within weeks after that. Lips move constantly when you talk and eat, and the dose is small. Ask your nurse injector what timeline to expect for your dose.
A gummy smile is usually treated a little differently from a lip flip. Instead of the muscle around the mouth, the injection targets the muscles that lift the upper lip, so the lip rises less when you smile and covers more of the gums.
A 2022 meta-analysis of 17 studies in Clinical Oral Investigations found an average reduction of about 3.4 mm in gum display two weeks after treatment. The authors found it especially effective for gummy smiles of up to 4 mm, lasted at least 12 weeks, and returned close to the starting point within 24 weeks. Your nurse injector can tell you which approach fits your smile.
A lip flip changes how the lip sits; filler adds volume. Filler is a different product, usually a hyaluronic acid gel, and the FDA notes that some dermal fillers are naturally absorbed by the body over time.
| Lip flip | Lip filler | |
|---|---|---|
| Price at InjectCo | $199 | $399 half syringe, $699 full syringe |
| What it does | Rolls the upper lip outward | Adds volume and shape |
| Product | Botox | Dermal filler, usually hyaluronic acid |
Some people combine the two. For a full side-by-side, read our guide to lip flip vs lip filler, and for filler pricing details, see lip filler cost.
Lip flips start with a nurse assessment.
Lip flip $199. Botox $12 per unit, or $7.77 per unit with membership ($24.99/month).
Side effects in the research were mild and short-lived. The 2025 review reported trouble whistling or drinking through a straw that resolved within weeks. In the 2026 study, every participant had at least one mild effect, most often upper lip numbness, along with oral numbness, localized pain, and general discomfort. All of these cleared within 30 days without treatment.
The BOTOX Cosmetic label carries a boxed warning: in rare cases, the toxin’s effect can spread beyond the injection site and cause problems such as difficulty swallowing or breathing, which can be life-threatening. The label also lists allergic reactions.
Talk with your nurse injector before booking if you:
Your nurse injector will give you aftercare steps before you leave.
If anything looks uneven or concerns you after treatment, contact your nurse injector.
A lip flip at InjectCo is $199 at all nine Texas locations. Your nurse injector confirms your total before treatment.
A 2025 systematic review found lip flips typically use 4 to 6 units of Botox. Your nurse injector sets the exact dose after watching how your upper lip moves.
Not long. In a 2026 study, the measured lift peaked at 15 days, was no longer significant at 30 days, and was back to baseline at 90 days. Your own timeline may differ with your dose and how active your lips are.
A gummy smile is usually treated by relaxing the muscles that lift the upper lip, which differs slightly from a lip flip. A 2022 meta-analysis found that approach reduced gum display for at least 12 weeks.
Your nurse injector will give you aftercare steps before you leave. Follow those for the first day or two after treatment.
Talk with your provider first if you’ve had an allergic reaction to a botulinum toxin product, have a neuromuscular condition or an infection near the lips, are pregnant or breastfeeding, or rely on fine lip control as a singer or wind player.
A lip flip is a small, temporary change with a clear price: $199 at InjectCo. It rolls your upper lip outward without adding volume, typically with 4 to 6 units, and the research suggests the effect is short-lived.
Your nurse injector will look at how your lip moves and tell you whether a lip flip, filler, or a gummy smile approach fits what you want to change.
Meet a nurse injector at any Texas location.
