Jawline Treatment: Filler, Botox or Radiesse?

Most guides to the best jawline treatment pick a favourite product and explain why it wins. This one starts a step earlier. A jawline can look soft, wide or blurred for very different reasons, and each reason has its own fix. Filler adds shape where bone support is missing. Botox slims a bulky chewing muscle. Radiesse adds firm structure and then builds collagen.

Below you will find a simple way to tell the causes apart. You will also see what the controlled trials found for each option, how long results lasted, and what each costs in the Klang Valley.

This guide is written by BeauLife Clinic, an MOH-registered aesthetic clinic (KKLIU 1970/2019) with LCP-certified doctors, operating since 2017 at five Klang Valley branches: Bukit Jalil, Cheras, Puchong, Subang Jaya and Ampang.

To start, a facial plastic surgeon explains when jawline filler helps, when Botox is the better tool, and why many faces need a bit of both.

1. Which jawline treatment suits your face shape?

Quick Answer: Match the treatment to the cause. A wide, square jaw from a large masseter (chewing) muscle suits Botox. A short, receding or soft jaw line from missing bone support suits firm HA filler or Radiesse. Jowls from loose skin suit tightening devices, and fat under the chin suits fat reduction. Many faces have two causes at once.

Three points explain the table:

• Muscle bulk is a width problem. Botox relaxes the masseter, so the muscle shrinks over a few weeks and the lower face looks narrower. Our guide to Botox face slimming covers this in detail.
• Missing support is a shape problem. From middle age, the jaw bone itself shortens. A CT study of 120 adults found jaw height and length fell with age in both men and women, while the jaw angle widened. Filler or Radiesse rebuilds that edge.
• Loose skin and fat are separate problems. Adding volume to a sagging jaw can make the face look heavier. These need tightening or fat reduction instead.

2. Filler, Botox or Radiesse: what do trials show?

Quick Answer: All three work better than no treatment in controlled trials. Radiesse improved the jawline in 75.6% of patients at 12 weeks, against 8.8% of untreated controls. A firm Restylane-type gel reached 85.1% against 14.3%. Juvederm Volux reached 69.0% against 38.0%. Jaw Botox gave a two-grade slimming in 51.2% against 2.2% on placebo.

What the numbers mean for you:

• Filler and Radiesse change shape on the day. The jaw edge is sharper as soon as the swelling settles. A 2026 meta-analysis of Volux jaw studies also found consistently higher response than in controls.
• Botox narrows the face slowly. In the phase 3 trial the lower face was on average 5.24 mm narrower at day 90, against almost no change on placebo. Results held to day 180.
• The control groups matter. Some untreated people in the Volux trial also “improved” on the scale, which is why the gap between groups is the useful number.

3. How long does each jawline treatment last?

Quick Answer: Jaw Botox lasts about four to six months; trial results held to day 180. HA jawline filler lasts about one to two years: one firm gel still worked for 67.1% of patients at 12 months and 69.0% at 24 months. Radiesse held for 62.9% at 48 weeks, rising to 74.6% at 60 weeks with a repeat treatment.

Three practical points follow from the timeline:

• Botox is a maintenance plan. Most people repeat it two or three times a year at first. Some find they need it less often later.
• Firm gels outlast soft ones. The jaw moves less than the lips, so firm jaw gels tend to last longer. Our guide to how long dermal fillers last compares products and areas.
• A repeat treatment extends the result. In both the Restylane-type and Radiesse studies, people who had a second session kept more of the improvement.

4. How much does jawline treatment cost in Malaysia?

Quick Answer: In the Klang Valley, jaw slimming Botox typically costs about RM 1,000 to 4,500 for both sides. HA jawline filler usually needs two to four syringes, about RM 2,400 to 14,000 with Restylane. Radiesse typically starts from about RM 3,000 per syringe. Skin tightening for the lower face and jaw runs about RM 4,500 to 7,500.

What moves the total:

• How much product. A small chin-and-angle touch may use one syringe. A full jaw line from ear to chin often takes three or four.
• How often you repeat. Botox costs less per visit but adds up over two years. Filler costs more up front but is repeated less.
• Combination plans. A wide jaw with a short chin may need Botox and filler, which our Juvederm liquid facelift page shows in a lower-face plan.

Price alone will not tell you the best jawline treatment for your face; a cheaper option that targets the wrong cause is money spent on nothing.

5. What helps a sagging jawline or double chin?

Quick Answer: Filler and Botox do little for loose skin or fat. A sagging jaw from lax skin usually needs a tightening device such as Thermage or Ultherapy Prime, sometimes with a small amount of filler near the jaw angle. Fat under the chin suits fat-dissolving injections or fat freezing.

When the jaw line is blurred by skin or fat rather than shape, the plan changes:

• Loose skin and early jowls. Energy devices heat the deeper layers so collagen tightens over two to three months. Our Thermage FLX skin tightening page covers lower face and jaw sessions, and our guide on how to tighten jowls lists what you can try at home first.
• Fat under the chin. Fat-dissolving injections such as Aqualyx typically start from about RM 699 per session. Our guide to chin fat removal treatment compares melting, freezing and tightening.
• Lost support plus loose skin. A doctor may combine a tightening device with filler at the jaw angle and chin, since adding support can reduce the pull on the skin.

For deep folds that run from the mouth towards the jaw, our guide to instant deep wrinkle filler explains which gels suit marionette lines.

6. What are the risks of jawline filler and Botox?

Quick Answer: Most side effects are mild and short-lived: swelling, tenderness, bruising and small lumps after filler, and a tired feeling when chewing after jaw Botox. Rare risks include filler blocking a blood vessel and, with too much Botox, a changed smile. Radiesse cannot be dissolved, so the doctor’s skill matters most there.

What the trials reported:

• Filler. In the Restylane-type jaw trial, treatment-related side effects occurred in 14.5% of patients, all mild or moderate. In the Volux trial, most injection-site reactions settled within two weeks.
• Botox. A 12-month CT study found no measurable change in jaw bone after masseter Botox. The most common side effect was difficulty chewing, in 6.0% of patients. In a phase 2 trial, a few people on the highest dose noticed a change in their smile.
• Radiesse. Effects were mostly mild in the 60-week follow-up, but it cannot be removed with an enzyme as HA filler can.

The US FDA warns that any filler can rarely block a blood vessel. In Malaysia, check your doctor on the MeRITS medical register; fillers are medical devices regulated by the Medical Device Authority. Our guide to choosing a safe aesthetic clinic in Malaysia explains what else to check.

Five questions to ask at your consultation:

1. Name the cause. Ask the doctor whether your concern is muscle, bone support, loose skin or fat, and why.
2. Name the product. Ask which product, how many units or syringes, and where each will go.
3. Ask about reversal. Ask what happens if you dislike the result: HA filler can be dissolved, Botox wears off, Radiesse cannot be removed.
4. Check the doctor and box. Check the doctor on the MeRITS register and ask to see the sealed product opened in front of you.
5. Agree the full cost. Ask for the total price for the full plan, including any planned repeat sessions.

7. The short version

There is no single best jawline treatment for everyone. Botox narrows a jaw that is wide from muscle. Firm HA filler or Radiesse rebuilds a jaw that is short or soft. Tightening devices and fat reduction deal with loose skin and a double chin. The BeauLife Clinic homepage lists every treatment and our five branches.
