When considering injectable treatments, one of the most common questions is how long the results will last. The lifespan of injectable treatments is influenced by many factors, including the type of product used, the area treated, your metabolism, lifestyle and how consistently you maintain your result. 

In this article, we’ll explain how long the most popular injectable treatments typically last, including dermal fillers, lip fillers, anti-wrinkle injections or regenerative treatments such as polynucleotides.

How Long Do Dermal Fillers Last?

How long dermal fillers last varies from person to person and depends on several factors, including:

  • The type of filler used
  • The area treated 
  • The amount of product required
  • Metabolism and lifestyle
  • Injector skills

Visible results from dermal fillers usually last around 9 to 12 months, and for some people, they can last even longer. To keep your face looking fresh and well balanced, we recommend a maintenance or review visit once a year.

When we talk about how long fillers last, it does not mean that they suddenly disappear after this time. You will still be enjoying many of the benefits, such as improved definition, volume and lifting. However, when compared to your initial results, you may notice that the effects are starting to soften slightly. This is why the one-year mark is the ideal time for maintenance.

Your initial treatment is a more involved process and may require more filler to build and shape your desired look. Maintenance treatments, on the other hand, are much smaller in scale, and smaller amounts of filler are used to simply refresh and preserve your results.

How long do lip fillers last?

Lip fillers typically last between 6 and 12 months, but this can vary from person to person. Longevity depends on factors such as the type of filler used, how your body metabolises it and the technique and approach of the injector.

For most first-time patients, it is best to start conservatively. It often takes two to three treatments to gradually build the lips to their fullest and most natural-looking shape. Slow, layered treatments create better balance and reduce the risk of overfilling. Once this foundation is established, lip fillers tend to last longer because volume has been built up gradually over time.

It is also important to know that fillers do not suddenly disappear. Many people feel their filler is gone when, in reality, it is still present. Visually and physically, the lips often still hold volume, which is why coming back too early can increase the risk of overfilling and migration.

How long does cheek filler last?

Cheek fillers can last between 12 and 24 months. However, this does depend on the type of filler used and the amount. Cheek filler can last longer, as there’s less movement in the cheeks compared to the lips. We would still recommend coming in for small touch-ups, usually around every year. This helps maintain the result you love and keeps the filler looking fresh and balanced over time.

How long does chin filler last?

Chin filler typically lasts between 12 and 18 months, with a maintenance treatment recommended at around 12 months to keep results looking their best. This treatment helps create a more defined, structured and balanced facial profile.

How long does nose filler last?

Nose filler typically lasts between 12 and 18 months, and in some cases even longer. This depends on the type of filler used, the amount placed and how quickly your body metabolises it.

Maintenance treatments are often recommended around the one year mark. This does not mean the filler has disappeared, but rather that a small amount can be added to maintain the results if required. Regular maintenance can actually help the filler last longer overall. With this approach, many patients find they need less product and can go longer between treatments while still maintaining a refined, natural-looking result.

How Long Do Anti-Wrinkle Injections Last?

Anti-wrinkle injections typically last 3-4 months with the right dose. The more consistent you are with treatments, the more consistent your results tend to be. Over time, you find the dose and time frame that works best for you. After a couple of years, many patients notice that at the 3 to four 4 mark they still look good and can sometimes stretch treatments a little longer. 

Anti-wrinkle injections are not one-size-fits-all. Your age, metabolism, lifestyle, hormones, pregnancy history and treatment consistency all play a role in how long results last and how much product you may need.

How Long Do Polynucleotides Last?

The effects of polynucleotides typically last between 6 and 12 months. However, this can vary from person to person and depends largely on individual metabolism and lifestyle factors.

Most patients begin to notice improvements in their skin within 2 to 3 weeks, although for some it can take up to 3 months to see the full results. Because polynucleotides work at a regenerative, cellular level, the changes are gradual and continue to improve over time.

This treatment is designed to be carried out as a course, usually three to four sessions spaced around a month apart. With each session, results build, skin quality improves and collagen stimulation becomes more noticeable.

The benefits of polynucleotides for collagen stimulation and overall skin quality are very strong, and it is a fantastic treatment for long-term skin health.
