Dermal Fillers

When Do Lip Fillers Settle?

One of the dermal fillers’ most exciting benefits is their quick settling. This article explains when lip fillers settle in an individual’s lip. The results of your lip fillers may last between 6 to 12 months.

Despite the negative publicity surrounding cosmetic procedures such as dermal fillers, their popularity is still blooming. Many clients are using dermal fillers for different reasons. Some use fillers for self-maintenance to eliminate signs of ageing that may start to show. They do this as part of their self-care routine to maintain a youthful look. Others opt for aesthetic treatments to correct face asymmetries or restore fullness to areas of their skin that have lost volume. Lip fillers give your lips a plumper and fuller look. Aside from that, they help you achieve a more proportionate lip shape. You will notice the results of a lip filler injection immediately after the procedure. However, they will look much more pronounced after the initial swelling and bruising goes down. The lip filler takes about four weeks to settle and produce the desired look.

What Are Lip Fillers?

Lip fillers are gel-like substances injected on the lips or around the lip area to enhance the appearance of your lips. Most people get lip fillers to add fullness to their lips, although there is still more than that. One can also get lip filler injections to correct lip asymmetries, for example, disproportionate lips. Lip fillers can also be used to smooth out wrinkles or make the shape of the lips more prominent. This non-surgical cosmetic procedure can be a great option for people looking for ways to treat signs of ageing without a permanent commitment. Lip fillers are made with synthetic materials or substances that occur naturally in the body. Most of them consist of hyaluronic acid (HA), a naturally-occurring substance in the skin. The type of filler you choose for your lips depends on one’s ultimate goal for the treatment, to get a defined lip shape or add fullness to the lips.

How Long Do Lip Fillers Take to Set in Position?        

Dermal fillers, including lip fillers, produce instant visible results after the injection. Typically, it takes approximately four weeks before the filler fully settles. Patients should drink more water during this period and keep their skin hydrated. After the injection, it is normal to experience swelling or bruising, which goes away within days, usually 5 to 7 days. Most cosmetic doctors advise their clients to be extra careful for at least four weeks after the procedure to avoid disrupting the filler as it settles into place.

Benefits of Lip Fillers         

Non-Invasive Procedure

Patients who want to modify the appearance of their lips with lip fillers do not have to undergo any physical surgery. Besides, the procedure is quick and usually performed within 30 minutes.


Lip fillers are not only used to add fullness to the lips but can be used in other ways, including:

  • Achieving a well-defined cupid’s bow
  • To smooth out wrinkles  and fine lines around the lip area
  • Reducing the appearance of perioral and marionette lines
  • Correcting lip asymmetries


Compared to surgical procedures, lip fillers are safe. Most lip fillers contain hyaluronic acid, a natural substance that occurs in the body. When injected into the body, hyaluronic acid provides a natural appearance and maintains a more youthful look without any severity. And because hyaluronic acid is a naturally-occurring substance in our bodies, not so many people are allergic to it.

Results Are Long-Lasting

A lip filler injection can last for 6 to 8 months. One may also need a top-up injection to maintain their desired look that may last even longer.

Lip Fillers Are Reversible

A previous lip filler injection may not result as expected, and one may need to change the appearance. It is completely possible. If that happens, an enzyme known as hyaluronidase is injected into the lips to dissolve the filler. People can add more stuffing if they want to achieve more pronounced results.

Common Side Effects of Lip Fillers         

Like any other cosmetic procedure, lip fillers also have mild side effects. Most side effects occur shortly after injection and go away within a few weeks. In some cases, they may occur weeks, months or years later. Common side effects include:

  • Pain
  • Swelling
  • Itching
  • Bruising
  • Rash
  • Redness

When to See a Cosmetic Doctor

While the above side effects are seen as normal, clients may experience more serious complications requiring them to see a cosmetic doctor. One may need to see a cosmetic doctor if they share the following difficulties:


Lumps usually improve with gentle massage over time. But if they continue, one must see a cosmetic doctor for further correction. Wege et al. (2021) stated that deeper lumps are removed through a surgical procedure if they do not disappear independently. Lumps resulting from hyaluronic acid may be dissolved by injecting hyaluronidase enzyme into the spot where one feels lumpy.

Prolonged Swelling or Bruising

Singh & Nooreyezdan (2020) stated that swelling and bruising are normal after having a lip filler injection. However, if they extend for more than seven days, ensure one check with your cosmetic doctor. This complication may occur in patients allergic to the lip filler ingredients.

Cold Sores

Black & Jones (2021) explained that if one is prone to a cold sore, having a lip filler injection may trigger reinfection.

Vascular Occlusion

The labial area is full of blood capillaries, and injecting the filler into a blood vessel may result in vascular occlusion. According to Alam et al. (2021), vascular occlusion occurs when the blood flow reduces or stops. That is why you need to get your lip filler injections from a highly qualified cosmetic doctor to minimize the risks of such complications.

Lip fillers consist of hyaluronic acid (HA) or other dermal fillers that make the lips look plumper and fuller over time. This cosmetic procedure is less invasive and has mild side effects that usually go away within a few days. However, ensure that you get the treatment from a board-certified cosmetic doctor.
