Treatment

What is a contour injection?

A contour injection is an injectable treatment used to refine small, stubborn areas of facial fullness. In Korean clinics these injections are widely used for the area under the chin, the jawline and the lower cheeks, where soft fullness can blur the outline of the face.

Berry Slim is Re:berry Clinic's own contour injection program. The formulation and dosing are chosen by the doctor according to the area and your skin. Because products and protocols differ, the specifics of what is injected, how many sessions are planned and how they are spaced are explained during consultation.

How does Berry Slim fit into contouring?

Contour injections are designed for localized, pinchable fullness rather than overall weight. They are not a weight-loss treatment. For many patients, the clearest outline comes from combining layers: an injection for a targeted pocket, a device for broader contour, and lifting where laxity is part of the picture.

Why is Berry Slim often paired with ONDA?

ONDA uses microwave energy designed to target fat tissue while protecting the skin surface. Berry Slim targets small, defined spots by injection. Used together within one plan, they approach the same concern from different angles. Your doctor decides whether a combination is appropriate and how to sequence it. Learn more on our ONDA Face Lifting page.

Who might Berry Slim suit?

Adults with a small double chin or soft fullness under the jaw
People whose jawline looks blurred by localized fullness rather than muscle
Patients with puffy lower cheeks who want a slimmer look without surgery
Those who prefer a gradual change with short downtime

It is usually less suitable when the main cause is a large chewing muscle, which responds better to jaw Botox, or significant skin laxity, which may need lifting. Pregnancy, breastfeeding, active skin infection, certain medical conditions and allergies to ingredients are common reasons to avoid or postpone treatment.

What happens during treatment?

Diagnosis: the doctor examines whether your fullness comes from fat, swelling, muscle, laxity or bone structure.
Area mapping: the target zone is marked so the injections stay within the planned area.
Preparation: skin is cleansed; cooling or numbing may be offered.
Injection: small amounts are placed with a fine needle across the mapped area.
After care briefing: you receive instructions on swelling, sleeping position and when to return.

The injection part typically takes 10–20 minutes. A first visit takes longer because of consultation.

How many sessions will I need?

Contour injections are usually done as a series rather than once. Many clinics space sessions about one to two weeks apart, and the total number depends on the area, the amount of fullness and how your skin responds. Your doctor will propose a schedule and review progress at each visit. If you are in Seoul only briefly, mention this when booking, since it affects whether the series can be completed during your trip.

What results can I expect?

Changes are usually gradual and subtle, building over the course of the series. Many patients describe a cleaner jawline or a less puffy lower face rather than a dramatic transformation. Results vary by individual and are influenced by weight changes, diet, sleep and fluid retention. Maintaining a stable weight helps preserve the result.

Side effects and aftercare

Common, temporary effects include:

Swelling and redness at the treated area, often lasting one to three days
Tenderness, a warm sensation or mild itching
Small bruises at injection points
Small firm spots that usually soften within days

Rare effects can occur and are discussed during consultation. To help recovery, avoid alcohol, saunas and intense exercise for a day or two, sleep with your head slightly elevated the first night, and do not massage the area unless instructed.

Tips for visitors planning Berry Slim in Seoul

A contour series needs several visits, so it suits a longer stay or repeat trips. If you are only in Hongdae for a few days, the doctor may suggest starting with a device such as ONDA or a single-session option instead, and continuing the injection series on a later visit. Avoid booking the first session the day before a flight if you are prone to swelling.

Berry Slim compared with other contour options

Berry Slim: injection for targeted pockets; short sessions; usually a series.
ONDA: microwave device for broader contour; no needles; sessions spaced over weeks.
Jaw Botox: relaxes the masseter; for muscle-driven width, not fat.
Lifting devices: Ulthera or Thermage for laxity that blurs the jawline.

Pricing and booking

Multilingual consultation support is available; please confirm languages when booking.

Is Berry Slim a fat-dissolving injection?

Berry Slim is Re:berry's contour injection program for localized fullness. The exact formulation and how it works for your area are explained by the doctor at consultation, because products and dosing are individualized. It is designed for small areas, not general weight loss, and results vary by individual.

Can I have Berry Slim and ONDA on the same day?

Some plans combine them, but the timing depends on the area, your skin and the protocol your doctor chooses. In some cases they are scheduled on separate days. Ask at consultation, especially if you are visiting Seoul for a limited time, so the sequence fits your stay.

Will the area look swollen after the injection?

Mild swelling is common and usually settles within one to three days. Under the chin it can feel slightly firm or tender at first. Plan important photos or events with a buffer of a few days. Sleeping with your head raised and avoiding alcohol can help the swelling resolve.
