Nuviju
A fat-reduction injection that reduces excess fat under the chin

It is a treatment in which NUVIJU, Medytox's injectable for improving submental fat, is placed in divided portions under the chin to reduce excess fat that has built up there. Its main ingredient, cholic acid, acts on fat cells in the injected area, and as the body gradually clears them away, the line under the chin changes toward a more defined look.

Treatments called fat-dissolving injections differ by product in ingredients and approved scope. NUVIJU, used for Nuviju, is a prescription medicine approved by the MFDS (Korean FDA) with the indication of improving moderate or greater submental fat. That is why we use it within the approved area and dosage, after examination.

No. Some people do have a lot of submental fat, but a double chin can also appear because the skin and fascia have sagged, or because of jaw structure or posture. Grays looks at fat and sagging separately, addressing excess fat with Nuviju and any accompanying sagging with radiofrequency and ultrasound (HIFU) lifting.

Swelling and a firm feeling in the injected area are common reactions. Bruising or a tingling sensation may come with them, and swelling usually settles over a few days to, at most, a few weeks. How fast swelling goes down differs from person to person, so if you have important plans, please let us know during your consultation.

It depends on the amount of fat and the change you want. Some people are satisfied after one session, but it is often carried out over several sessions. After the swelling has gone down sufficiently, we check the change and decide whether further sessions are needed and at what interval.

Because the fat cells have been reduced, the effect tends to last relatively long. However, remaining fat cells can enlarge if you gain weight, and skin sagging with age progresses separately, so how long it lasts varies by individual.

Swelling, bruising, pain, firmness and tingling are common. Rarely, the treatment may affect a nerve near the injection site, making mouth-corner movement temporarily uneven, or cause discomfort when swallowing, so we choose the injection points carefully. If you have such symptoms or the pain keeps getting worse, please contact us right away.

We do not perform it if you are pregnant or breastfeeding, or if there is infection or inflammation at the injection site. If you have a history of neck or under-chin surgery, thyroid disease, or difficulty swallowing, or if you are taking anticoagulants, please be sure to tell us during your consultation. The treatment is also not suitable if you have had a hypersensitivity reaction to its ingredients.

The cost varies with the injection area, volume and number of sessions, so it is confirmed after examination. Non-covered treatment fees can be found on the pricing page of our website.
