Everything You Need to Know

A lip flip is a quick, minimally invasive cosmetic procedure that uses a small amount of neurotoxin (Botox, Dysport, or Xeomin) injected into the orbicularis oris muscle — the muscle that surrounds the lips. Rather than adding volume, it causes the upper lip to gently "flip" outward and upward, making it appear fuller and more defined without adding filler.

The neurotoxin temporarily relaxes the muscle fibers at the border of the upper lip. When those muscles relax, the lip edge rolls slightly outward, revealing more of the pink lip tissue. The effect is subtle, natural-looking, and typically requires only 4–6 units of Botox.

The three most common FDA-approved neurotoxins used are: Botox (onabotulinumtoxinA) — the most widely used and well-known; Dysport (abobotulinumtoxinA) — comparable results with a slightly quicker onset; and Xeomin (incobotulinumtoxinA) — a "naked" neurotoxin without accessory proteins, which may reduce the chance of developing antibodies over time.

A lip flip uses neurotoxin to relax the lip muscle and create the appearance of a fuller upper lip — no volume is actually added. Lip filler uses hyaluronic acid (like Juvederm or Restylane) to physically add volume and shape to the lips. Many people combine both for optimal results. The lip flip is ideal for those wanting a subtle enhancement, while filler is better for significant volume.

Yes! A lip flip + filler combo is very popular. The flip creates definition and a gentle roll of the upper lip, while the filler adds volume and shape. The results are complementary. Your injector may recommend getting filler first and adding the flip after, or doing both in the same session depending on your goals.

Typically 6–8 weeks, which is shorter than lip filler (which lasts 6–12 months). Because the lip muscles are highly active — talking, eating, smiling — the neurotoxin metabolizes faster in this area. Most people schedule touch-ups every 2–3 months to maintain results.

Most patients describe it as a very minor pinch. The needle is very fine and the number of injections is small (usually 4–6 injection points along the upper lip border). Numbing cream can be applied beforehand if requested, though many patients find it unnecessary.

The national average ranges from $75–$150. Since it uses very few units of neurotoxin (4–6 units of Botox), it is one of the most affordable cosmetic procedures available. Prices vary by region, provider credentials, and which product is used.

Great candidates include people who want subtle enhancement without added volume, those whose upper lip tends to "disappear" when they smile, people who want their upper lip to show more, those new to cosmetic procedures who want a low-commitment option, and anyone who prefers a natural look over a dramatic change.

Avoid blood thinners (aspirin, ibuprofen, fish oil supplements) for 24–48 hours before your appointment to reduce bruising risk. Avoid alcohol for 24 hours prior. Arrive with a clean face — no lip products. Let your provider know about any medications or supplements you take.

Don't touch or massage the treated area for 4 hours. Avoid strenuous exercise for 24 hours. Don't lie face-down for 4 hours after treatment. Avoid extreme heat (saunas, hot yoga) for 24 hours. Results begin to appear in 3–5 days, with the full effect visible at about 2 weeks.

The lip flip is considered very safe when performed by a qualified provider. Possible temporary side effects include mild bruising, slight swelling, or asymmetry. In rare cases, too much neurotoxin can cause difficulty drinking through a straw or puckering the lips for a few weeks. Always choose a licensed, experienced injector.
