Fill cheeks

Fill cheeks at KNAP Institute

Injured cheeks can quickly give your face a tired and outdated appearance. This can be caused by various reasons. A treatment with injectables can offer a solution! By treating your cheeks with fillers, you will get a fresh, young and healthy appearance again in the foreseeable future. You can have this effective treatment done by the qualified and experienced cosmetic doctors at KNAP Institute.

About our treatment

Hollow cheeks

There are several causes for sunken cheeks, but the most common are skin aging and weight loss. Because the cheeks lose their volume, they can ‘hang’ or attack. This will quickly give you a tired and gruff look. A filler treatment for your cheeks can help you and make sure that you look youthful and radiant again!

Causes sagging cheeks

The two major causes of subsidence at the cheeks are aging and weight loss. The image below clearly shows how the shape of a face changes over the years. This is because our bones, including the jawbone, wear as we age. This causes the skin to hang more because space is created. In addition, the skin is also weakened, because our fat tissue decreases. The cosmetic doctors at KNAP Institute restore the skin’s volume through a filler treatment. Because the skin gets tighter, this also reduces the shadows in the face that make us look older.

Cost of treatment

The costs of injectables depend on the quantity and the area to be treated. However, you do not want to face unexpectedly high costs. That is why we discuss in advance with you how the treatment works and what costs are involved. This way you know exactly where you stand. Naturally, your budget will be taken into account as much as possible.

Safe and trustworthy

The cosmetic doctors at KNAP Institute work according to internationally established guidelines. They use materials and techniques that have been extensively tested and comply with all cosmetic conditions. This makes the treatment reliable and guarantees safety. Furthermore, they are regularly updated by attending conferences and presentations. Because of this they are always aware of the latest (technological) developments and techniques.

The treatment

Injured cheeks are filled during treatment and corrected with fillers.
These so-called injectables have the effect that the skin retains more moisture at the cheeks. As a result, the skin appears to be more filled, so that wrinkles and subsidence become much less visible. By the fuller cheeks, you get a young and vital appearance.

For a result that is as natural as possible, we first look closely at your own image. The treatment is fully attuned to this.


The recovery after treatment with fillers is generally quite fast. However, you should take care of your skin in the right way for optimal results. A number of things that you should take into account:

  • After the treatment, the skin can often feel sensitive and turn red. Try to touch the skin as little as possible and certainly not scratch or rub! In some cases there is a slight swelling and small bruising. However, these will disappear within a few days.
  • Avoid (excessive) exposure to sun or UV radiation. Protect your skin at least with a sunscreen with sunblock.
  • Do not use make-up and perfume for at least 10 hours after treatment.
  • Do not expose your skin to extreme temperatures for one week after treatment, such as in a sauna, under the solarium or in a steam bath.
  • Painkillers such as ibuprofen or aspirin can have a stimulating effect on bruising. For this reason, these are not recommended. If you still want to use a painkiller, paracetamol is recommended.


Frequently Asked Questions

All materials and techniques have been extensively tested and the treatments comply with international cosmetic conditions. You can therefore expect treatments with fillers to be safe and reliable. If you have any questions or doubts, you can always contact KNAP Institute.

If you treat your skin correctly after treatment and follow the guidelines, you will experience fewer side effects. However, redness, tenderness, local small bruises, bruising and slight swelling may occur. However, these will completely decrease after a few days.

That differs per person and depends on your sensitivity. Some patients experience it as almost painless, others suffer more from it. It is possible to stun the area to be treated. This is done in consultation with your doctor.
