Excess fat in the armpit area is quite common, especially in sedentary individuals or those prone to fat accumulation. To address this problem, armpit fat-dissolving injections are attracting much attention from women. So, are armpit fat-dissolving injections effective? What precautions should be taken? In the article below, HBIO Clinic will answer all your questions.
Overview of Armpit Fat-Dissolving Injections
Essentially, armpit fat-dissolving injections are a form of mesotherapy, often referred to as meso injections or micro-injections. The doctor will use a specialized needle to inject a sufficient amount of active substance into the subcutaneous fat layer in the armpit area.
The active substances commonly used in this method are phosphatidylcholine and deoxycholate. These are components that can break down the structure of fat cells and promote local fat breakdown.
After being injected into the subcutaneous fat layer, the active substances will directly affect the fat cell membrane. When cell membranes are broken down, fat cells are gradually broken down into smaller molecules.
The broken-down fat is then eliminated by the body through the lymphatic system and natural metabolism. This process takes several weeks, helping the layer of fat under the armpits to thin over time.

Are underarm fat-dissolving injections effective?
After underarm fat-dissolving injections, the body needs time to break down and eliminate the fat. Typically, noticeable results begin after about 4-6 weeks.
A treatment course usually includes 3-5 injection sessions for optimal results. After the course, the underarm fat layer can be reduced by an average of 1-2 cm.
However, specific results depend on several individual factors such as:
- Quality of nutrients: The active ingredients used in underarm fat-dissolving injections must have a clear origin and be safety-tested to ensure effective fat breakdown.
- Underarm fat condition: People with low to moderate fat levels usually see results faster than those with thick fat or general obesity.
- Diet after injection: After underarm fat-dissolving injections, maintaining a healthy diet and gentle exercise will support the fat elimination process.

What are the advantages and disadvantages of underarm fat dissolving injections?
Understanding the pros and cons of this method will help you make the best decision.
Advantages of underarm fat dissolving injections
Below are the outstanding advantages of underarm fat dissolving injections:
- Minimally invasive: The method does not require surgery and only uses small needles to inject the active ingredient into the subcutaneous fat layer, resulting in relatively low invasiveness.
- Quick procedure time: An underarm fat dissolving injection session usually only lasts 15-20 minutes and does not cause prolonged pain.
- No long recovery time needed: After the injection, you can return to normal activities on the same day if you follow the doctor’s aftercare instructions.
Disadvantages of underarm fat dissolving injections
Some limitations of this method that you should be aware of include:
- Requires multiple treatment sessions: To achieve noticeable results, you usually need 3-5 treatment sessions depending on the initial amount of fat.
- The effectiveness is also influenced by lifestyle habits: after the injection, in addition to the effect of the method, you also need to adjust your eating and exercise habits to maintain the results.
- Side reactions may occur: some people may experience mild swelling, bruising, or stinging at the injection site, but these symptoms will gradually subside after a few days.

When should you AVOID underarm fat dissolving injections?
Although it’s a minimally invasive procedure, underarm fat dissolving injections are not suitable for the following cases:
- People under 18 years old: Their bodies are still developing, so invasive cosmetic procedures are not recommended.
- Pregnant or breastfeeding women: The active ingredients used in fat-reducing injections can affect the health of both mother and baby.
- People with blood clotting disorders: Those taking anticoagulants or with related conditions have a higher risk of bruising and bleeding.
- Areas with inflammation or infection: If the underarm area has open wounds, dermatitis, or infection, injections may worsen the condition.
