A double chin is a blurred transition between face and neck, caused by fat under the chin and loosening skin. Contrary to popular belief, it isn’t only seen in people who are overweight; it can appear at a healthy weight too.

Several causes usually play a part together:

• Local fat: fat can build up under the chin regardless of your weight.
• Skin laxity: collagen declines with age and the skin under the chin starts to sag.
• A weak jawline: a small or receding chin makes a double chin more noticeable.
• Muscle pull: the platysma muscle in the neck pulls the lower face down and softens the jawline.
• Genetics and posture: family traits and a habitually forward head position can also affect the look.

That’s why no single double chin treatment suits everyone. Treatment is planned around the cause, and several methods are often combined.

At our clinic, non-surgical double chin treatments are planned alone or together, depending on the cause:

• PB Serum: an enzyme-based injection that helps break down fat cells under the chin; often used for a double chin.
• Meso lipolysis: supports targeted fat reduction with mixtures injected into the fat layer, on the same principle as other mesotherapy treatments.
• Onda Pro: a device that heats fat tissue with microwave energy, with a dedicated handpiece for small areas such as the double chin; no needles or incisions.
• HIFU / LIFU: tightens the skin with focused ultrasound; its deeper mode also helps reduce fat under the chin.
• Jawline filler: supports the jawline and chin, which helps reduce the look of a double chin.
• Nefertiti lift: relaxes the pull of the platysma so the jawline looks more defined.

Fat-reducing methods (PB Serum, meso lipolysis, Onda Pro) and tightening or supporting methods (HIFU, jawline filler, Nefertiti lift) target different problems, so the right combination is decided after your assessment.

Planning starts with a detailed examination of the under-chin and neck area. The doctor looks from the front and side and assesses the thickness of the fat, skin elasticity, chin support and muscle pull.

1. Noticeable fat, firm skin: fat-reducing methods usually come first.
2. Little fat, loose skin: tightening methods take priority.
3. A weak jawline: supporting it with jawline filler can noticeably reduce the look of a double chin.
4. Muscle pull: a Nefertiti lift may be added to the plan.

The number of sessions and the spacing depend on the method. For example, PB Serum usually needs 2–3 sessions for a double chin, while meso lipolysis is planned as a course of several sessions 10–15 days apart. Your exact plan is decided at consultation. With marked sagging, other non-surgical facelift options may also be considered.

Most double chin treatments need no recovery time, and you can return to your day straight away. Depending on the method, you may notice:

• After injections: mild swelling, tenderness and small bruises under the chin for a few days.
• After device treatments: brief redness and a feeling of warmth.
• After filler or botox: mild swelling and tenderness at the injection points.

Because there can be some swelling under the chin in the first days after injections, plan treatment well before an important event. Drinking plenty of water, eating a balanced diet and staying active support the results of fat-reducing methods.

These treatments are not given during pregnancy or breastfeeding, with an active infection in the area, or with a known allergy to the product used. Always mention any medication you take at your consultation.

With fat-reducing methods, the broken-down fat cells are cleared by the body over several weeks, so results appear gradually and are assessed once the sessions are complete. Keeping a stable weight helps results last; noticeable weight gain can bring fat back to the area.

The effect of tightening and supporting methods is temporary. With HIFU, the collagen effect develops over months, while filler and botox are repeated at intervals depending on the product. How to maintain the result is planned together at your follow-up.

In Dr. Sevgi Ekiyor’s approach, the double chin is assessed together with the jawline and neck, so the lower face is treated as a whole.
