If you want your lips to look a little fuller or more defined, two treatments often come up: lip filler and the lip flip. They are sometimes mentioned as if they were interchangeable, but they work in completely different ways and suit different goals. If you are weighing up lip filler in Dubai against a lip flip, this guide explains what each one does, how long effects usually last, what affects the cost, and how to decide which fits what you want.
Both are medical treatments. Results vary between people, and a licensed doctor should assess your lips and explain which option, if either, suits you.
What lip filler does
Lip filler adds volume. Most lip fillers are made from hyaluronic acid (HA), a gel based on a molecule that occurs naturally in the skin and helps it hold water. The filler is injected into or around the lips to:
- Add fullness to the upper lip, lower lip or both
- Define the lip border and Cupid’s bow
- Improve symmetry between the two sides or between the lips
- Soften fine lines around the mouth
- Add hydration and a smoother look
Because filler physically adds volume, the change is visible straight away, although swelling in the first few days means the final look settles over time.
HA filler is not permanent. The body gradually breaks it down, and in many cases it can be dissolved with an enzyme called hyaluronidase if needed.
For a step-by-step look at the process, read our guide to what happens before, during and after lip filler treatment.
What a lip flip does
A lip flip does not add volume. Instead, it uses a very small amount of botulinum toxin, a prescription-only medicine, injected into the muscle just above the upper lip border.
This muscle, which circles the mouth, naturally pulls the upper lip slightly inward when you smile or speak. When a small dose relaxes it, the upper lip can roll slightly outward, so more of the pink part of the lip shows. The result is a subtle change in how the upper lip looks, rather than added fullness.
A lip flip is often considered by people who:
- Feel their upper lip “disappears” when they smile
- Want a very subtle change
- Have a gummy smile, where a small amount of toxin may also be used
Results are not immediate. Changes usually appear over several days, with the full effect around two weeks after treatment.
Some temporary effects are specific to a lip flip, because the lip muscle is slightly relaxed. These can include difficulty drinking through a straw, whistling or pronouncing certain sounds, and, occasionally, slight dribbling. These usually settle as the effect wears off.
If you are considering a lip flip in Abu Dhabi or Dubai, your doctor should explain these effects before treatment.
Results and how long they usually last
| Lip filler | Lip flip | |
|---|---|---|
| What it changes | Adds volume and definition | Rolls the upper lip slightly outward |
| Which lips | Upper, lower or both | Upper lip only |
| When you see a change | Straight away, settling as swelling goes down | Over several days, with the full effect around two weeks |
| How long it usually lasts | Generally longer than a lip flip; varies by product and person | Generally shorter than filler; varies by person |
| Reversibility | HA filler can often be dissolved | Wears off on its own |
How long either treatment lasts depends on the individual, the product, the dose, metabolism and lifestyle factors. No clinic can guarantee a specific duration.
Cost factors
The cost of each treatment depends on several factors.
For lip filler:
- The product used
- The amount of filler needed
- Whether the aim is subtle hydration, definition or more volume
- The doctor’s training and experience
- Whether a review appointment is included
For a lip flip:
- The product used
- The small dose needed
- Whether it is combined with other areas, such as a gummy smile
- The doctor’s experience
A lip flip usually involves less product than lip filler, but it may need repeating more often. When comparing costs, think about both the price per treatment and how often you may choose to repeat it.
Be cautious about very low prices or treatment outside licensed clinics. Both treatments should only be performed by licensed professionals using genuine products.
Which one suits which goal
A simple way to think about it:
- You want more volume or fullness: lip filler is usually the more suitable option.
- You want sharper definition or better symmetry: lip filler can help shape the border.
- You want a subtle change to how the upper lip shows when you smile, without added volume: a lip flip may suit you.
- You are trying a lip treatment for the first time and want something very subtle: either may be discussed, depending on your anatomy.
- You want both a subtle flip and a little volume: some people combine the two, with timing planned by their doctor.
Lip filler and lip flips may not be suitable if you are pregnant or breastfeeding, have an active cold sore or infection around the mouth, or have certain medical conditions. A lip flip is also not suitable for people with certain neuromuscular conditions.
The best way to decide is a consultation, where a doctor can examine your lips, smile and facial proportions. You can read more about lip fillers on Skin111’s lip fillers page.
