Many people are concerned about stubborn fat that does not go away easily with exercise alone. In particular, office workers near Cheongdam-dong and brides-to-be often inquire about fat-dissolving injections. People sometimes ask, "Can’t I get the injections every day if I want to see results quickly?" However, no matter how effective a medication may be, the body needs time to absorb and respond to it, so it is most important to keep an appropriate treatment interval.

- A principle similar to the process of melting solid ice

To make the mechanism of fat-dissolving injections easier to understand, it is similar to pouring warm water over a hard block of ice and letting it melt. The fat cells accumulated in our bodies are tightly clumped together and bound strongly, making it difficult to break that bond with exercise or diet alone.
At this point, the injection treatment loosens and breaks down the rigid fat cell membranes, turning the fat into a softer, more fluid state. The broken-down fat residues then move through the blood vessels and lymphatic vessels and are expelled from the body in the form of waste products such as sweat or urine. In other words, the fat does not disappear the moment the injection is given; only when the series of processes of breakdown and elimination proceed smoothly can a reduction in size be expected.
- Why a one-week interval is ideal

So why is an interval of 1 to 2 weeks usually recommended? This is closely related to the body’s physiological cycle. It takes roughly one week for the medication to be administered, stimulate and break down fat cells, and for the resulting waste products to be fully eliminated from the body through lymphatic circulation.
If you rush and receive another treatment after just 2 to 3 days, the new stimulation may be added before the previous medication has even fully taken effect, which can place unnecessary strain on the body. On the other hand, if the interval is too long, such as more than a month, the weakened fat cells may have time to clump together again or recover, making the treatment less efficient, like pouring water into a bottomless bucket. Therefore, the key is to keep providing consistent stimulation before the fat cells settle again, maximizing the breakdown efficiency.
- The golden time for drinking water, as important as the procedure itself
If you keep the treatment interval properly, the key to boosting its effect by 200% is water intake. As mentioned earlier, broken-down fat must be eliminated through urine or sweat to completely leave the body. Water acts like the truck that carries those waste products away.
If your body lacks water, even if the fat has been well broken down, it may not be eliminated and could circulate within the body and be reaccumulated. That is why, during the treatment period, it is recommended to drink plenty of water, at least 2 liters a day. In particular, the first 3 days after the procedure are when the breakdown process is most active, so drinking water frequently during this time and combining it with light aerobic exercise or stretching can promote lymphatic circulation and help you experience faster changes in your body line.
- Customized cycles based on different fat layer thicknesses from person to person

Of course, a one-week interval is the general standard, but it does not apply equally to everyone. Just as people have different facial features, the thickness of fat, the degree of cellulite, muscle mass, and the speed of response to medication all differ from person to person.
At Cheongdam Dermatology Clinic, we do not provide a uniform, factory-style procedure; instead, we propose a 1:1 customized plan that takes each person’s body type and fat characteristics into account. Through a safe yet effective treatment interval and thorough aftercare, we hope you can complete the body line you want in a healthy way.
