Wegovy and Mounjaro, the weight-loss injections currently hugely popular in Korea.
You often see them on social media and in reviews, but
you may find yourself wondering, “Which one is actually right for me?” 🌀
Here, we’ll clearly summarize and introduce the differences, effects, side effects, and how to choose between the two injections!
💉 What are Wegovy and Mounjaro?
Both were originally developed as medications for treating diabetes.
However, their significant weight-loss effects have attracted attention,
It is now being used at the forefront of medical weight loss✨
Its availability at Korean aesthetic clinics is rapidly increasing,
and inquiries from Japanese people are also growing year by year.
Especially in the Gangnam area,
clinics offering safe and effective medical weight loss
are emerging one after another.
📌 Basic Information on Wegovy (Wegovy)
The active ingredient is semaglutide.
It is a type of drug called a GLP-1 receptor agonist, which works to suppress appetite.
The convenience of just one injection per week is also appealing.
It has been officially approved as an obesity treatment medication in the United States and Europe,
with extensive clinical data having been accumulated.
Because it has a proven track record in both safety and effectiveness,
it is also a medication often chosen by beginners to medical weight loss💡
📌 Basic Information on Mounjaro (Mounjaro)
This medication uses an ingredient called tirzepatide.
Its distinctive feature is its dual action on both GLP-1 and GIP receptors💪
Like Wegovy, it is administered as one injection per week,
but its mechanism of action is slightly different.
By targeting two receptors simultaneously,
it is a highly anticipated medical weight loss medication expected to provide greater weight reduction effects.
🔬 Detailed Explanation of the Differences in Effects
Effects of ウゴービ
ウゴービ has been reported to result in an average weight loss of 15–17% in clinical trials (※individual results may vary).
Many people begin to notice changes within several weeks to about one month after starting,
and in many cases, appetite itself decreases.
- You feel full sooner
- It becomes easier to feel satisfied with smaller portions
Therefore, its defining feature is that the amount you eat naturally decreases without having to follow a highly stressful diet.
Effects of マンジャロ
マンジャロ has been reported to have an even more powerful weight-loss effect than ウゴービ.
Clinical trials have shown an average weight loss of 20–22% (※individual results may vary).
Through the dual action of GLP-1 and GIP,
- it not only suppresses appetite
- but also improves glucose metabolism
- and increases energy expenditure
These effects can also be expected.
For this reason, it is extremely important to carefully adjust the dosage under the supervision of a specialist💡
For those who did not achieve sufficient results with ウゴービ,
or those who want to lose weight more proactively,
more and more people are choosing マンジャロ as their “next step.”

🌟 Key Points for Success
It is important not to rely solely on injections, but also to review your lifestyle habits.
Here are some tips for making effective use of medical weight loss treatment.
🍽️ Focus on a nutritionally balanced diet
Make sure to consume a balanced amount of protein, vegetables, and moderate carbohydrates.
Extreme dietary restrictions can be counterproductive. Ideally, your food intake should naturally decrease while you continue to get adequate nutrition.
🚶♀️ Keep up light exercise
Continuing gentle exercise, such as walking and stretching, can help prevent rebound weight gain.
Try starting with about 30 minutes of light exercise a day.
💧 Stay well hydrated
Hydration is also important for managing side effects. Aim to drink about 2 liters a day, taking small sips regularly.
Especially when your appetite is reduced due to side effects, be sure not to forget to stay hydrated🥤
