Chin and jaw augmentation
with hyaluronic acid

Chin and jaw augmentation with hyaluronic acid and biocompatible substances at Clínica Sanza in Barcelona consists of filling the chin and jaw area with temporary substances, such as hyaluronic acid or calcium hydroxyapatite.

They are infiltrated with injections, do not require surgery and are performed in the same office. They are absolutely biocompatible, they do not produce any type of rejection or subsequent problems in the patient’s body.

How long do the results of injecting hyaluronic acid into the chin and jaw last?

The duration of hyaluronic acid once injected into the chin and jawline can vary depending on several factors. In general, the duration of the results can range from 12 to 18 months or even longer if the product is of high quality.

Hyaluronic acid is a resorbable material, which means that over time it is broken down and metabolized naturally in the body. The rate of resorption can be affected by the concentration and cross-linking of the hyaluronic acid used, as well as the individual’s location and metabolism.

In areas that are not as exposed to movement, such as the chin and jawline, the results can last longer than in areas with movement, such as the lips.

It is important to keep in mind that the duration of results can also be affected by post-treatment care and individual lifestyle habits.

How is hyaluronic acid injected into the chin and jaw?

Hyaluronic acid is carefully injected into the skin layers using a fine needle or cannula. Sometimes several punctures are necessary to distribute the product well and obtain an optimal result.

Don’t just go anywhere. It is essential to keep in mind that learning how to inject hyaluronic acid safely and effectively requires proper training and in-depth knowledge of facial anatomy, injection techniques and the appropriate choice of hyaluronic acid for each patient. Performing these injections without proper training and experience can have risks, such as injury, swelling, bruising or allergic reactions in the patient.

At Clínica Sanza we use the best hyaluronic acid we know, the one that lasts longer, the one that gives the best results.

Beware of saving money at a low-cost center, the result will not last.

Can I socialize or work the next day?

Yes, you do not need to rest unless you have a profession with risk of hitting the area. What we advise is to avoid going to the gym for the first two days.

You may have small bruises that go away in 24 to 48 hours and minimal swelling.

If you do not like the result, it is reversible

One of the fears of people who come to cosmetic medicine offices asking for a chin and jaw filler is that they will not like the result. If you fear that your chin and jawline have too much volume or if you don’t like the shape, it can be left as it was. The most important thing with this treatment is that the result is natural and matches your face.

HYALURONIDASE ! this magic word is your peace of mind.

It is an enzyme that has the ability to degrade hyaluronic acid. In the field of aesthetic medicine, hyaluronidase is used to dissolve hyaluronic acid in cases where you do not like the result, due to complications or adverse reactions caused by hyaluronic acid dermal fillers.

Differences between filling with Calcium Hydroxyapatite or Hyaluronic Acid

Hyaluronic acid and calcium hydroxyapatite are two substances used in aesthetic treatments to increase volume in the chin and jaw. The differences between the two are explained below:

1. Composition and mode of action:

    • Hyaluronic acid: It is a molecule naturally present in our skin and is used to moisturize and restore volume in the treated area. It provides natural and temporary results, as it is gradually absorbed by the body. It is applied to the superficial layers of the skin.

    • Calcium hydroxyapatite: It is a collagen biostimulator, which means that it promotes the production of collagen by skin cells. In addition to providing volume, it also has a tightening effect and contributes to the firmness of the most superficial layers of the skin. The results can be long lasting due to the formation of new collagen. It is used in deeper layers of the skin.

2. Treatment areas:

    • Hyaluronic acid: Used to augment the chin and jawline, improve the appearance of scars, rejuvenate a woman’s intimate area, correct imperfections on the back of the nose and treat fine wrinkles. It can also be used to increase volume in the cheekbones and lips.

    • Calcium hydroxyapatite: Used to restore volume to facial structures, redensify the skin and provide firmness to the most superficial layers of the skin. It can be used on areas such as the chin and jawline, but is not recommended for reducing wrinkles between the eyebrows and forehead.

3. Side effects:

    • Hyaluronic acid: It is a biocompatible and well-tolerated substance, so side effects are usually minimal and temporary, such as redness or swelling that disappear in a few days. As a substance found naturally in the body, it does not usually have significant contraindications.

    • Calcium hydroxyapatite: Calcium hydroxyapatite is also well tolerated, but caution should be exercised when injecting it in certain areas, such as the eye area, to avoid complications. As with hyaluronic acid, redness, swelling or bruising may occur at the application site, but these are usually temporary and mild..


People who wish to improve their jaw profile in a simple and non-definitive way.


The infiltration is performed by means of microinjections applied to the area to be augmented.

The materials most commonly used for this type of cheek augmentation are hyaluronic acid (temporary) and bone powder, which are biocompatible with the body and have a similar consistency to the tissue in which they are implanted. They are almost totally imperceptible to the touch, and they are also chemically and physically stable over time, so that a natural but not definitive result can be achieved.

It is usually performed in several sessions to achieve the desired volume progressively.
