A lot of people are still unsure. If you sweat a lot, especially under your arms, you might avoid wearing light-colored clothes or feel self-conscious lifting your arms. Botox has become a popular solution, but many still wonder—how does it work? Does it stop body odor? Will it reduce underarm hair?
This article answers all your questions in a super easy Q&A format—whether armpit Botox is right for you, what problems it helps solve, and what to know before getting it done.
Q1: What is the injection used in armpit Botox and how does it work?
It’s a simple concept: Botulinum Toxin Type A is injected into the underarm area to block sweat glands from overproducing sweat, helping to reduce excessive sweating and body odor.
Q2: What are the benefits of armpit Botox?
Armpit Botox is convenient, safe, and effective. It directly targets sweat glands to reduce both sweat and odor—unlike deodorants or perfumes that only mask odor temporarily without solving the root cause.
Q3: If I sweat a lot, how much can Botox help?
Within 2–4 weeks after the injection, sweat typically reduces by up to 80%. With less sweat comes less odor. The effect lasts around 3–4 months before gradually wearing off. How long it lasts may vary by individual.
Q4: Why does Botox help reduce body odor?
The injections are done at a shallow level—just under the skin where sweat glands are located. By reducing moisture and bacteria (which are the main causes of body odor), armpit Botox indirectly helps control odor.
Q5: How is Botox different from using deodorants or antiperspirants?
Deodorants just mask odor for a few hours. Botox targets the root cause—sweat glands—resulting in dry underarms and fewer chances of odor forming. Plus, the effects last for months with no need for daily reapplication.
Q6: Is armpit Botox a permanent solution?
No, it’s not permanent. It temporarily reduces the function of sweat glands. After 3–4 months, the glands gradually become active again. If you want to maintain the results, you can repeat the treatment when the effect starts to wear off.
Q7: Will it make my underarms look smoother or fairer?
Some people feel their underarms look smoother because there’s no more sweat. However, Botox doesn’t directly whiten skin or reduce pigmentation. If you're aiming for brighter, smoother underarms, you might need additional treatments.

Q8: Can Botox help with bumpy or “chicken skin” underarms?
Botox is mainly for sweat reduction. If you have chicken skin, pairing Botox with laser treatments—like keratosis pilaris or hair removal lasers—can help smoothen the skin texture.
Q9: Does armpit Botox reduce underarm hair?
No. Botox only affects sweat glands. It has no effect on hair growth.
Q10: Who is armpit Botox suitable for?
It’s great for people who sweat excessively, experience body odor, or want to boost their confidence in clothing—especially during photoshoots, events, or daily life without the worry of sweat stains or odor.
Q11: Can you get Botox if you’re pregnant or breastfeeding?
Even though no serious side effects have been confirmed for pregnant or nursing women, it’s best to wait until after giving birth and breastfeeding before getting the treatment—just to be safe.
Q12: Do I need to remove underarm hair before getting Botox?
If possible, avoid shaving or plucking 1–2 days before your appointment to prevent irritation. Also, make sure the underarm area is clean beforehand.
Q13: Is it painful? Do you use numbing cream or ice?
The underarm is a sensitive area, so a slight sting during injection is normal. At MEGA CLINIC, we offer ice packs during the procedure and can also apply numbing cream if you prefer.
Q14: Are there any side effects after getting armpit Botox?
You may notice small injection marks or slight tightness in the underarm area. These effects are temporary and usually disappear within a few hours. People with very sensitive skin might experience minor bruising.
Q15: Can I get laser hair removal after Botox?
It’s best to wait about a week. Heat from the laser could affect the Botox and reduce its effectiveness in controlling sweat and odor.
Q16: Can I exercise after getting armpit Botox?
Yes, you can exercise normally. Just avoid heat-heavy activities—like saunas, steam rooms, and certain laser treatments—for the first week.
Q17: How many units of Botox are used for underarm injections?
Doctors usually use 100–150 units for both underarms, depending on the individual.
Q18: Is it dangerous to get armpit Botox injections often?
Not at all—as long as it’s done by a qualified doctor using authentic, FDA-approved Botox in proper doses. Follow the recommended intervals and it’s safe to repeat the treatment without worry.
Q19: Is the Botox used under the arms the same as for the face?
Yes, it’s the same Botulinum Toxin Type A. However, the dosage and injection techniques differ based on the treatment area and goal.
Q20: How much does armpit Botox cost?
100 units: 6,500 THB
