Seeing reviews from people who were swollen for days after getting fat dissolving injections might make you hesitate. Many of our patients put off scheduling because they're worried about how the swelling will affect their busy lives, even though the results look great.

However, over the past few years, there has been a wonderful shift toward minimizing the swelling burden. This is being achieved through options like cholic acid and our unique formulation that combines anti-inflammatory ingredients with a cannula technique.

In short: Cholic acid* (Newviju) is a gentle new ingredient designed to reduce swelling and pain. Double Slim is our in-house formulation designed for a smoother contour by combining anti-inflammatory ingredients with a specialized cannula technique.

Why Does Cholic Acid Lead to Less Swelling?

The ingredient getting the most attention lately is Cholic Acid*. Newviju, developed by Medytox, is the world's first cholic acid-based fat dissolving injection and has been officially approved as a new domestic drug in Korea.

* Cholic acid: A type of bile acid. It has a lower surfactant activity than deoxycholic acid, making it known for causing significantly less swelling and pain.

While both belong to the bile acid family, there is a key difference. Cholic acid has lower surfactant activity, which greatly reduces the irritation phase—meaning less of the swelling, pain, and bruising that are common with deoxycholic acid injections. Think of it as a gentler approach that breaks down the fat membrane while being much kinder to the surrounding tissues.

Additionally, its pH matches that of our bodies to ensure effective fat destruction while excluding chemical additives that might trigger allergies or skin reactions. In large-scale clinical trials, a high percentage of patients reported a noticeable improvement in submental (double chin) fat. Knowing the official drug clearance information is always a reassuring benchmark for both safety and effectiveness.

Double Slim — Smoother Contours with Anti-Inflammatory Ingredients & Cannulas

Another wonderful way to minimize swelling lies in how the treatment is performed. This is beautifully illustrated by Double Slim, a custom formulation we use in our clinical practice.

Two key elements make this possible. First, we add anti-inflammatory ingredients to help lessen the swelling after your procedure. Second, we perform the treatment using a cannula*.

* Cannula: A thin tube with a rounded tip. Instead of making multiple pricks with a sharp needle, it slides smoothly under the skin, which significantly reduces bruising and needle marks.

Instead of using sharp needles to make multiple injections, we use a rounded-tip cannula to gently glide under the skin and evenly distribute the formulation. This minimises bruising and puncture marks, allowing for a much smoother recovery. Please keep in mind that since this is an in-house formulation, individual experiences may vary—but it is a popular option designed specifically for those wanting a faster, more comfortable recovery.

Frequently asked questions

Q. Is cholic acid less effective than deoxycholic acid?

A. Rather than being weak, it's designed to minimize irritation. Both are destructive treatments that reduce fat cells, but Cholic Acid is specifically formulated to lower swelling and pain. You can choose the best option based on your fat volume and goals.

Q. Who is the Double Slim treatment recommended for?

A. For those who want to minimize swelling and bruising, and desire a smooth, refined result, the cannula approach is highly recommended. However, since this is a custom-formulated treatment, we determine the best approach after an individual consultation for each case.

Q. Does less swelling mean a faster recovery?

A. Since it is highly gentle, the swelling period is relatively short. However, individual results may vary, and above all, the precise location and depth of the injection play a much greater role in both your recovery and safety.

Q. Is Cholic Acid (which causes less swelling) or Double Slim always the better choice for everyone?

A. Not necessarily. If you have a significant amount of fat and definitely want a strong reduction, deoxycholic acid might be the right fit for you. On the other hand, the colanic acid and cannula approach is designed to ease the burden for those who want to see visible results without letting swelling disrupt their daily routine.
