Fat Dissolving Injection
What is FatX Core?
FatX Core is a fat dissolving injection formulated with the maximum concentration (1%) of deoxycholic acid, an FDA-approved fat dissolving component.
Compared to conventional fat dissolving injections, it is highly effective at destroying and removing fat cells, with no risk of rebound. Additionally, collagen is produced in place of the destroyed fat tissue, so even after the fat is gone, the skin does not sag and a tightening effect can be expected.
You can see visible results in a short period, and targeted fat reduction is possible for both the face and body.

About the Medications We Use
Deoxycholic acid, the main ingredient in FatX Core, works by destroying the cell membranes of fat cells, thereby reducing their number. Higher concentrations can yield greater results; however, higher concentrations also tend to cause more swelling and longer downtime.
The FatX Core used at our clinic features a specially formulated blend of plant-derived amino acids called the NAIS complex, which minimizes post-treatment swelling and puffiness, while maintaining a high concentration of deoxycholic acid with minimal downtime.
The primary ingredient of FatX Core is deoxycholic acid, which is FDA-approved for its high safety profile and works as a bile acid to dissolve fat. It also contains the patent-pending NAIS complex -- plant-derived amino acids that reduce post-treatment swelling and pain -- along with ingredients whose safety has been verified through over 10 years of clinical testing. After treatment, the ingredients do not accumulate in the body but are expelled through protein binding.
After fat cells are removed, repair cells gather to produce collagen, which prevents new fat formation while also preventing skin sagging and creating firm, elastic skin.

Treatment Details
| Results | Many patients notice results approximately 2 weeks to 1 month after swelling subsides. Individual results may vary. Once results appear in the treated area, the effect is generally long-lasting. However, please note that rapid weight gain may cause remaining fat cells to enlarge, making the effect less noticeable. |
| Treatment duration | Face (cheeks + under chin): approx. 10-15 min. Body (upper arms): approx. 10-15 min. *Varies depending on the area and extent of treatment |
| Anesthesia | Generally not required, but nitrous oxide sedation and anesthetic cream are available. |
| Pain | Sufficient cooling is applied, so the pain is tolerable. |
| Treatment interval | You can feel the effect even with a single treatment, but receiving approximately 3 sessions at 1-month intervals will maximize the results. |
| Makeup | Point makeup is possible from the same day, avoiding the injection sites. |
| Washing & bathing | Face washing and showering are possible from the same day. Bathing in a tub is possible from the following day. |
| Downtime | We use very fine needles and inject with the utmost care at our clinic. However, bruising cannot be completely avoided when needles are used. If bruising occurs, the discoloration will fade over approximately 2 weeks, during which time you can cover it with makeup. If you have an important event coming up, we recommend scheduling your visit at least 2 weeks in advance in case bruising occurs. |
| Risks | - Itching, pain, swelling, bruising, allergic reactions, and infection may occur. - In some cases, insufficient volume may result in weaker effects. (Additional injections are available after 2 weeks, though additional fees apply.) |
| Precautions | The following individuals cannot receive this treatment: - Those under 18 years of age - Those planning to become pregnant within 3 months - Those who are pregnant, possibly pregnant, or breastfeeding - Please refrain from massaging the injected area for 2 weeks after treatment. - Those with systemic neuromuscular junction disorders (ALS, myasthenia gravis) - Those with severe peripheral arteriovenous conditions - Those with severe liver disease - Those with immunodeficiency or autoimmune diseases - Those undergoing chemotherapy - Those with ulcers or infections on the skin near the treatment area - Those with eczema or psoriasis - Those with excessively high expectations |
