How Long Do the Best Lip Injections Last?

Feeling like your lips are a bit low these days? With a simple lip injection procedure, you can get plump, luscious lips to make people do a double-take. But, how long do those lip injections last? It’s a good idea to know what you’re signing up for before you take the leap yourself!

How Do Lip Injections Work?

There are a few different ways to do lip injections, but each of them serve the same purpose. The injection is put behind your natural lips to make them plumper and rounder. You can help to round out vertical spots or flat lips with an injection. Most lip injections aren’t permanent, so they will fade off after some time as the injected substance is absorbed by your body.

Different Types of Lip Injections

Lips injections can be done with a few different methods. These are the main three:

- Fillers

Injections themselves are usually fillers. There are collagen, autologen, and hyaluronic acid-based fillers. All are injected behind the natural lips to plump them out. Each type of filler can be made up of different formulas from each separate company that makes them. You’ll be able to make a choice about which brand you want to use for your own injections.

- Fat Grafting

With this method, fat will be taken from somewhere else on your body and injected behind your lips. It’s a longer-lasting method, but it is more involved than a filler injection and can have a much longer recovery time.

- Silicone or Artecoll Injections

These are also lip injections available to everyone, but they’re riskier and much more involved than the normal filler injections or fat grafting. The main appeal of these lip injections is the long-lasting effects, but the cost and higher risk of messing up your lips can make them an unattractive option.

How Long Do Lip Injections Last?

Each lip injection type has its own timeline, and some branded formulas do better than others. Your doctor will be able to advise you on which one might work best for what you want. But, it’s good to know the general timelines for each type so you can make a better decision.

Silicone &Artecoll

The longest lasting injections are silicone and artecoll. In most cases, they’re considered permanent implants. You can have them removed if you want to later down the road, but your body won’t reabsorb all of the materials. Some of the initial injected silicone or artecoll can be absorbed by the body, but usually a small percentage that won’t affect the overall look.

Although a permanent lip injection sounds great, this is the riskiest way to do it. It’s easier for bumps, inflammation, or nodules to develop. Most doctors don’t recommend this injection because of those risks, but also because the cost is much higher than that of other types of injections.

Fat Grafting

Since the injected materials are actually your own fat taken from another part of your body, fat grafts last for longer than fillers. They’re not permanent, but it’s possible for them to stay for a few years at a time. Most estimates say up to 2 – 3 years is the longest you can expect a fat grafting lip injection to last.

It will take longer for you to get a fat injection done than other filler injections. First, the doctor will have to take some fat from another part of your body using liposuction. After that, they’ll inject the fat in small amounts around your lips to plump them out. It’s a longer process each time you do it, but it will stay full for longer than fillers. There are more risks during the procedure than for a regular filler, since there the process is more involved.


Common lip injection fillers like Juvederm and Restylane all have similar timelines, though their formulas are not exactly the same. Most fillers last for around 6 – 8 months at maximum. If you get a double application to plumper lips, they can last for 8 – 12 months in some circumstances. The timelines can vary a lot depending on your body and your metabolism.

If you have a higher metabolism, your body is going to absorb the filler material more quickly. All fillers will be reabsorbed over time, but your metabolism will determine how quickly it happens for you. Natural fillers like collagen and autologen tend to last for a shorter time than hyaluronic acid fillers, because the body can more easily absorb them. Autologen is longer-lasting than collagen.

With fillers, your doctor should always test for allergies before you begin the procedure. If there is an allergic reaction, you’ll have to have it removed before any more damage can be done. Autologen is taken from another spot in your own body, which eliminates the risk of allergies, whereas collagen and hyaluronic do have some risk of allergies. Be careful using bovine collagen formulas, since the risk will be much higher with these formulas than with human collagen formulas.

What Affects Lip Injections in Your Body?

I already mentioned metabolism as a factor for how long lip injections last, but it’s not the only thing that can make a difference. Here are the other factors that can make a difference for you:

- Your Doctor

Not all plastic surgery doctors have the right level of experience. Those with more experience tend to know what to do to prolong the injections for you. They can also offer advice about what you can do specifically to help your body maintain the injections for a longer time.

- Touch-Ups

You can get touch-up procedures that are less involved than a full lip injection. These little touch-ups help to keep your look the way you want it, and can extend a normal filler’s lifetime up to 12 months or more.

- Your Age

Younger people have more of the natural filler materials in the body already, like hyaluronic acid, autologen, and collagen. Because of this, younger people won’t metabolize the natural fillers as quickly and they will last longer.

People beyond the age of 50 don’t have as high of levels of these three materials. So, they will metabolize the fillers more quickly than younger people and may need more frequent touch-ups for long-lasting results.

- Complementary Procedures

Lip injections done by themselves will have the estimated timelines I mentioned before, but some procedures done at the same time can extend their life. Botox is the most common procedure to prolong lip injections.


The right lip injections can really take your style to the next level. Talk with your trusted plastic surgery doctor about which injection might be right for you, and which one will last the longest with great results!
