Lip Flip 101: What It Is, How It Works & If It’s Right for You

a subtle enhancement with a big impact

If you’ve ever wanted a slightly fuller-looking upper lip — without adding volume or committing to filler — a lip flip may be exactly what you’re looking for. This subtle injectable treatment has become increasingly popular for its natural-looking results and minimal commitment.

In this guide, we’re breaking down what a lip flip is, how it works, who it’s best for, and how it compares to lip filler so you can decide if it fits your goals.

what is a lip flip?

A lip flip is a cosmetic injectable treatment that uses a small amount of Botox (or a similar neuromodulator) to relax the muscles around the upper lip. By softening this muscle, the upper lip gently “flips” outward, creating the appearance of a fuller lip without adding volume.

Unlike dermal filler, a lip flip does not increase the size of the lips — it enhances shape and visibility instead.

how does a lip flip work?

The upper lip naturally curls inward when we smile, speak, or move our mouth. For some people, this can make the upper lip appear thin or disappear altogether when smiling.

A lip flip works by:

relaxing the muscle that pulls the upper lip inward
allowing the lip to roll slightly outward
enhancing the shape of the upper lip at rest and when smiling

The result is subtle, balanced, and natural-looking.

lip flip vs. lip filler: what’s the difference?

This is one of the most common questions we hear — and the answer depends entirely on your goals.

lip flip

uses Botox, not filler
enhances lip shape, not volume
best for subtle definition
shorter-lasting results
minimal commitment

lip filler

adds volume and structure
enhances size, shape, and symmetry
longer-lasting results
more customizable

A lip flip is ideal for clients who want a softer enhancement or are new to injectables. Lip filler is better suited for those seeking noticeable volume or reshaping.

In some cases, the two treatments can be combined for a balanced result.

who is a good candidate for a lip flip?

A lip flip may be a great option if:

your upper lip disappears when you smile
you want subtle enhancement without added volume
you’re new to injectables
you want a low-commitment treatment

It may not be ideal if you’re looking for dramatic fullness or significant reshaping — in those cases, filler may be more appropriate.

A consultation with a trained provider is essential to determine what’s best for your anatomy and goals.

what to expect during treatment

Lip flip treatments are quick and efficient, typically taking less than 15 minutes.

You can expect:

a few small injections around the upper lip
minimal discomfort
little to no downtime

Because the area is delicate, you may experience mild swelling or tenderness, which typically resolves quickly.

when will I see results?

Lip flip results are not immediate. Botox gradually takes effect over several days.

initial results: 3–5 days
full results: 7–14 days

As the muscle relaxes, the upper lip becomes more visible and defined.

how long does a lip flip last?

Because the lip muscles are used frequently, lip flips tend to wear off faster than other Botox treatments.

Most clients can expect results to last 2–3 months. Regular maintenance helps preserve the effect over time.

are there any side effects?

Lip flips are generally well-tolerated, but temporary side effects can include:

mild swelling or bruising
slight changes in how the lip feels when speaking or drinking

These effects are temporary and typically resolve within a few days.

is a lip flip noticeable?

A lip flip is meant to be subtle. Friends may notice that your lips look more balanced or defined — but the goal is for results to look effortless, not obvious.

If you’re someone who prefers natural-looking enhancements, a lip flip is often a great place to start.
