Face Contour Injection

Contour injection, explained

What is a Korean face contour injection, and what does it actually do?

The short answer

A face contour injection is a series of small injections of a fat-acting preparation into a defined layer of facial fat, used to make the line of the cheeks, under-chin and jaw read lighter and sharper. Rewind's Korean page describes two effects: fat cells in the treated layer are broken down and excreted, which reduces their number, and puffiness in the area eases alongside. The clinic states that its injection contains no steroid and discloses the ingredients at consultation.

The phrase contour injection names a purpose. It tells you what the treatment is meant to achieve, a cleaner outline, without telling you which substance does it. The same Korean name can therefore be attached to preparations that contain quite different things, and the first useful question about any contour injection is what is in this one.

On effect, the clinic is specific about what it expects and modest about how fast. Its page says the clearest change generally appears after two to three sessions, depending on how much fat is present. A single appointment starts the change and leaves most of it to come.

From injection to outline

What happens between a contour injection and a smaller-looking face

The change comes in layers, and knowing their order explains why the face can look different at one week than at one month.

01Read

The face is measured first, the plan drawn second

The ultrasound scan separates superficial fat from deep fat and from the salivary gland, and the contour analyser records the outline from several angles. Only fullness confirmed as superficial fat becomes a target for the injection.

02Place

Many small deposits across one layer

The clinic describes injecting densely through the unwanted fat. Spreading the volume across many points is what lets a pocket shrink evenly instead of in patches.

03Clear

Fat cells break down over the following weeks

Laboratory work on deoxycholate, a substance studied in this category, describes a detergent action on fat cell membranes and a 2010 paper reports tissue-selective effects of injected deoxycholate. Rewind does not publish whether its own preparation contains it, so these papers explain the category without describing the product.

04Build

Two to three sessions add up to the visible change

Each session reduces a share of the fat in the treated layer. The clinic puts the clearest change after two to three sessions, and each is planned after the previous one has been reviewed in photographs.

Per appointment

What a face contour injection costs per appointment

The contour injection is listed per appointment at a published volume. The Korean event menu also pairs it with a jaw muscle injection for faces whose width is partly muscle, and that line is shown beside it.

List rates, VAT excluded. Anaesthesia fees are included in listed figures where anaesthesia is used; none is used for this injection. A larger volume is also listed on the Korean menu and is confirmed at the consultation.

Session by session

From the first contour injection to a smaller-looking face: the weeks in between

These cards follow the clinic's own aftercare and the progression it shows in its event material.

Swelling, bruising, tenderness and numbness over the area are expected. Firm nodules that soften over weeks and uneven response between sides can occur. A 2022 review of injections combining phosphatidylcholine and deoxycholate questions their risk profile in its title. Report increasing hardness, skin that darkens or breaks down, or an uneven smile to the clinic the same day.
