Chin filler: what it can and cannot do for your profile

How you are assessed

The doctor looks at your face from the front, in profile and at an angle. They assess where your chin sits in relation to your lips and nose, the height of the lower face, the shape of the jawline and how the chin moves when you speak and smile. They will also look at your bite and ask whether you have had orthodontic treatment or jaw surgery.

You will be asked about previous filler, dental work or infections, allergies, autoimmune conditions and medicines that make you bruise easily. If you have had filler in the chin before and do not know what it was, say so. A permanent filler changes the plan.

How long does chin filler last?

You see the change straight away, although swelling makes it look slightly fuller at first. The real result is the one you see at about two weeks.

The chin is an area of support that moves less than the lips, so the gel tends to last longer there. In a randomised trial in the United States, 81% of people treated improved by at least one grade on a validated chin scale at 12 weeks, against 6% of untreated controls. At 48 weeks, 74% still had that improvement, against 11% ^[3].

A second randomised trial of 200 adults found a response in 70% at six months, against none in the untreated group. At twelve months, 55% of those treated kept the improvement ^[4]. In a systematic review of 917 patients, most were satisfied with the result ^[5].

In practice, expect it to last around a year, sometimes more. The product, the amount, your metabolism and your face all play a part. Many people keep their result with a smaller top-up before it has gone completely.

What to expect, realistically

• A stronger, better-defined chin, in proportion with the rest of your face.
• A profile that looks more balanced, often with a nose that seems smaller.
• Firmness, tenderness and some swelling for a few days, sometimes a bruise.
• A review at two to three weeks, to decide whether a small adjustment is needed.

Chin filler will not lift loose skin under the jaw or remove a double chin caused by fat. Those need a different approach, and your doctor will say so.

Risks, and who it is not for

The usual effects are local and short-lived: swelling, bruising, pain, redness and itching where the gel was placed ^[5]. In the trial above, treatment-related side effects were mild to moderate ^[3]. Asymmetry and small irregularities can occur and can usually be adjusted at the review. Lumps or nodules, including late ones, are uncommon ^[6].

Serious complications are rare. In a retrospective study of more than 290,000 hyaluronic acid injections, they occurred in about 4 in every 100,000 ^[7]. The most important is vascular: gel entering or pressing on an artery. The chin is generally considered a lower-risk area, but its arteries connect with those of the floor of the mouth, and published cases describe damage to the tongue ^[8]. Those cases recovered fully with prompt, high-dose treatment with the enzyme that dissolves hyaluronic acid ^[8].

That is why technique and preparation matter. Most complications can be avoided with planning, knowledge of the anatomy and the right product, and the doctor must be ready to treat one on the spot ^[6]. The same principles apply to every area we treat, as we explain in our guide to lip filler.

Chin filler is not recommended in pregnancy or while breastfeeding, with an active infection of the skin, gums or teeth near the area, with an uncontrolled autoimmune condition, or after a severe reaction to filler. It is also not the right first step if the chin is retruded because of the jaw and you are considering surgery.

How to choose where to have it

Check that the clinic is a licensed healthcare centre, that a registered doctor assesses and treats you, and that you are told which product is used and why. Ask what would happen if a complication occurred, and whether a review is included. Our guide on how to choose an aesthetic clinic in Spain covers this in more detail.

If you live on the Costa del Sol, between Málaga and Marbella, or spend the season here, think about timing too. Leave a few weeks before a flight home or a family event, so there is time for the review.

How we approach it at Rejuvelook

At our clinic in Fuengirola we start with a medical consultation that looks at your chin as part of your whole face and profile. If filler is right for you, we explain what change is reasonable, which product we suggest and how much. We work with conservative amounts and see you again once it has settled. If your chin would be better served by a surgical opinion, we will tell you. We see patients in English or Spanish.
