A double chin can often be reduced without surgery by matching treatment to its cause. At Re:berry Hongdae, fat under the chin may be treated with ONDA microwave energy or a Berry Slim contour injection, while loose skin may respond to ultrasound or radiofrequency lifting. Several sessions are usually needed, and results vary by individual.

What causes a double chin?
A double chin, or submental fullness, usually comes from one or more of these factors:
- Submental fat: a pocket of fat under the chin, sometimes present even in slim people.
- Skin laxity: loosening skin and soft tissue with age.
- Anatomy: a small or recessed chin, or a low position of the hyoid bone.
- Posture: looking down at phones can make fullness more visible.
Identifying the main cause guides treatment, which is why Re:berry follows diagnosis before packages.
Which non-surgical treatments may help?
ONDA microwave energy
ONDA face lifting uses Coolwaves microwave energy that targets fat tissue, with skin cooling at the surface. It typically involves little downtime and 2–4 sessions. See ONDA for a double chin.
Contour injections such as Berry Slim
Contour injections are designed to reduce small, stubborn fat pockets. They may cause swelling, tenderness or bruising for several days. At Re:berry, Berry Slim is often paired with ONDA.
Ultrasound and radiofrequency lifting
When loose skin is the main issue, Ultherapy Prime, Thermage FLX or Sofwave may tighten the area under the chin and along the jaw over several months.
Chin filler
For a recessed chin, a small amount of filler can improve the profile so the area under the chin looks less full.
How long do results take?
Fat-reduction treatments usually show gradual change over 4–12 weeks after a series. Lifting results develop over 2–3 months. Maintaining a stable weight helps results last. Results vary by individual, and surgery or liposuction may still be more suitable for significant fat or skin excess.
Who should wait?
Pregnant or breastfeeding patients, people with active infection in the area, and those with implanted electronic devices (for ONDA) should discuss alternatives first. Book a consultation via our Booking page; pricing is confirmed in writing at consultation.

Related questions
Can exercise alone get rid of a double chin?
General weight loss can reduce submental fat for some people, but spot exercises for the chin have limited evidence. Fullness caused by genetics, skin laxity or chin shape may remain despite a healthy lifestyle. That is when non-surgical treatments may be considered after a doctor's assessment.
Is ONDA or a contour injection better for a double chin?
It depends on the amount and location of fat and how much downtime you can accept. ONDA usually has very little downtime, while injections may cause swelling for several days. Many plans combine both. The doctor will recommend an approach after examining the area.
Are results from double chin treatments permanent?
Treated fat cells may be reduced, but remaining fat can still grow with weight gain, and skin continues to age. Results are therefore long-lasting for many people but not guaranteed to be permanent. Keeping a stable weight and occasional maintenance help.
