Downtime at a glance
Needle marks and mild redness typically last a few hours to a few days; if bruising appears, expect around 1 week. The injection sites are usually hidden by clothing, so time off work is generally said to be unnecessary in most cases.
Typical downtime is A few hours to 1 week (if bruising appears, it usually fades almost completely within about 1–2 weeks), and most people feel comfortable being seen in public after Often possible from the same day (for palm injections, those who do a lot of fine handwork may feel more comfortable allowing a few extra days). How much swelling or bruising appears varies from person to person, depending on constitution and the extent of treatment.
Recovery timeline: treatment day to final result
Fine needle marks, redness, and mosquito bite–like bumps may appear at the injection sites. The bumps usually settle within a few hours. On the day itself, avoid rubbing the area firmly, and it is safer to skip strenuous exercise, alcohol, long baths, and saunas. For underarm treatment, you will generally be advised not to use antiperspirants or deodorants on the day of the procedure. Showering is often allowed from the same day, but follow your clinic's instructions.
For many people, redness and bumps become less noticeable by this point. If bruising is going to appear, small bruises may show up around this time, but since the underarms and palms are hidden by clothing, the impact on daily life is usually small. Desk work and going out are often possible as usual.
Needle marks and redness have mostly settled for many people by this stage. Those who respond early are said to start noticing reduced sweating around now. If the palms were injected, tenderness when pressing may remain, but it tends to ease gradually.
By this point, the visible downtime is barely noticeable for most people. Any bruising begins to fade. More people start to notice a change in how much they sweat, though how the effect appears varies from person to person.
The effect is generally said to be mostly complete by this time. It is a good point to check how much your sweating has decreased and whether there is any left–right difference, and to consult your doctor about anything that concerns you. For palm treatment, it is also reassuring to check around now whether your grip strength has changed.
Downtime has fully settled and the effect is stabilizing. This is when many people notice everyday differences, such as fewer sweat stains and changes in odor (the degree of effect varies from person to person).
The effect is not permanent and is said to fade gradually over about 4–6 months (this varies by area and individual). When you feel the sweating returning, it is time to discuss re-injection with your doctor. Many people are said to have the treatment every year before summer.
Bars show approximate swelling levels (individual results vary).
Common symptoms
| Symptom | Likelihood | When it appears | How long it lasts | Notes |
|---|---|---|---|---|
| Needle marks and small red dots | High | Immediately after treatment | A few hours to a few days | Because many small injections are placed in a grid pattern, fine needle marks and redness may appear temporarily, but they are said to settle within a few days in most cases. |
| Swelling and raised bumps (welts) | Medium | Immediately after treatment | A few hours to 1 day | Right after the injections, mosquito bite–like bumps may appear due to the product and the needle stimulation, but they usually become unnoticeable within a short time. |
| Bruising | Medium | Same day to the next day | 1–2 weeks | Bruising can occur when a needle nicks a small blood vessel. The underarms and palms are hidden by clothing, so bruises tend not to stand out in daily life. |
| Dull pain, stinging, and tenderness | Medium | Immediately after treatment to a few days | A few days | You may notice pain when pressing on the injection sites or mild stinging for a while. The palms and soles are easily irritated by walking and everyday tasks, so symptoms there can last somewhat longer. |
| Weaker grip or difficulty with fine hand movements (with palm injections) | Low | A few days to 2 weeks after | A few weeks to a few months (until the effect wears off) | If the product affects the small muscles of the hand, grip strength may temporarily weaken or pinching movements may become harder. This is said to fade as the effect wears off in most cases, but if your work involves a lot of handwork, discuss it with your doctor beforehand. |
| Feeling that sweating elsewhere is more noticeable | Low | Once the effect appears | Until the effect wears off | Because the treated area sweats less, some people feel that sweating in other areas stands out more by comparison. The degree varies from person to person; consult your doctor if it concerns you. |
When can I do what? (Daily-life restrictions)
| Activity | Typically OK from | Key point |
|---|---|---|
| Makeup | Usually fine as normal from the same day | For injections in areas other than the face, such as the underarms or palms, there is said to be little impact. If the forehead was treated (for scalp/forehead sweating), avoid rubbing the injection points firmly on the day of treatment. |
| Shower | Often allowed from the same day | It is safer to rinse the injection sites gently rather than scrubbing them. |
| Bathing (soaking in the tub) | From the next day | A long soak on the day of treatment boosts circulation and can make bruising and redness more likely, so it is safer to avoid it. |
| Alcohol | From the next day | Drinking on the day of treatment may make bruising more likely, so it is safer to avoid it. |
| Exercise | From the next day (light exercise) / strenuous exercise from around day 2–3 | Strenuous exercise right after treatment raises circulation and is said to sometimes lead to swelling and bruising. It is safer to hold off on heavily sweat-inducing exercise for a few days. |
| Sauna and hot-stone spa | From around day 2–3 | High heat promotes circulation and can make redness and bruising more noticeable, so it is safer to wait a few days. |
| Antiperspirants and deodorants (for underarm treatment) | From the next day to a few days later, as a guide | While needle marks remain, the skin can be easily irritated by these products, so it is safest to resume once the redness has settled. Follow your clinic's instructions. |
| Shaving the underarms | From a few days later, as a guide | A razor blade passing over needle marks can irritate them, so it is safer to wait until the redness has settled. Some clinics advise finishing hair removal by the day before treatment. |
| Medical laser hair removal (on the injected area) | From about 1–2 weeks later | Laser treatment while needle marks or redness remain can be irritating, so it is safest to wait until the skin has settled. Discuss the order and timing with your doctor. |
| Massaging or firmly pressing the injection sites | From about 1 week later | Firm rubbing has been noted as potentially spreading the product beyond the intended area, so it is safer to avoid it for a few days to a week. |
Pain and anesthesia
The typical pain level is Very mild. Underarm treatment is often performed without anesthesia, or with a topical numbing cream and/or cooling. For the palms and soles, a nerve block or nitrous oxide (laughing gas) may be used in addition to topical anesthesia. Options differ by facility, so please check the details with your doctor. Because the injections are shallow and use a fine needle, underarm treatment is generally described as a mild pricking sensation. The palms and soles, on the other hand, are more sensitive areas where pain tends to be felt more strongly, so some form of anesthesia is often considered. Sensitivity varies from person to person — if you are worried about pain, discuss it with your doctor in advance.
Tips for a smoother recovery
- Cooling the area right after treatment and avoiding activities that strongly boost circulation on the day itself — alcohol, strenuous exercise, long baths, saunas — tends to make bruising and redness less likely.
- If you bruise easily, or take blood-thinning medications or supplements, letting your doctor know in advance can help with managing the risk.
- For underarm treatment, avoiding tight or high-friction clothing for a few days reduces irritation to the injection sites. It is safest to resume antiperspirants once the redness has settled.
- If you want the effect in place for a sweaty season or an event (summer, a wedding, a presentation), allow about 2 weeks for the effect to fully appear and have the treatment 2–4 weeks before the big day.
Risks and side effects (the honest version)
- How the effect appears varies from person to person: the reduction in sweating may feel insufficient, there may be a left–right difference, or the effect may not last as long as expected. Assess the result around the 2-week mark when the effect is mostly complete, and consult your doctor about anything that concerns you.
- With palm injections, the product can affect the muscles of the hand, temporarily weakening grip strength or making fine tasks harder. This is said to recover as the effect wears off in most cases, but if you play an instrument or do precision work with your hands, discuss it carefully with your doctor beforehand.
- Bruising, swelling, and pain or stinging at the injection sites can occur. In rare cases the injection sites can become infected — see a doctor promptly if redness or pain worsens.
- Some people feel that sweating in untreated areas becomes more noticeable by comparison. Also, the effect on underarm odor itself (osmidrosis) is considered limited; if treating odor is your main goal, it is advisable to discuss other options with your doctor as well.
- Allergic reactions can occur in very rare cases. It has also been noted that repeating treatment at short intervals may lead to antibodies forming against the product, making it less effective.
- For areas such as the palms, soles, and forehead, the treatment may fall outside the domestically approved indications in Japan (off-label use), and some facilities may use products that are not approved in Japan. Make sure you receive an explanation in advance about the product used, the indications, and how side effects would be handled.
- The treatment may not be suitable for those who are pregnant or breastfeeding, or who have neuromuscular disorders, among others. If you have any medical conditions or take any medications, always tell your doctor in advance, and decide whether to proceed after being examined.
Spacing and combining with other procedures
If you have a specific occasion when you want sweating under control — summer, a wedding, a presentation — allow for the time it takes the effect to fully appear (about 2 weeks) and have the treatment 2–4 weeks before the day. Re-injection in the same area is generally considered once the effect starts to fade, around 4–6 months later. Because repeating treatment at short intervals has been noted as potentially leading to antibodies that reduce the effect, leave at least 3 months between sessions and follow your doctor's guidance on spacing and frequency.
| Combined procedure | Timing | Wait time | Reason |
|---|---|---|---|
| Botox Injection for Expression Lines (Forehead, Frown Lines, Crow's Feet, etc.) | Same day OK | Sometimes combined on the same day | Because both are injectable treatments using the same family of product, they can generally be done on the same day. However, there are guideline limits on the total dose per session, so your doctor will decide how to allocate the areas and amounts. |
| Medical Laser Hair Removal (Underarms) | Wait required | About 1–2 weeks, as a guide | Laser treatment right after the injections can irritate the needle marks and redness, and doing both on the same day makes the recovery harder to interpret. Some clinics prefer finishing the hair removal first and injecting afterward — plan it together with your doctor. |
| Microwave Treatment (for Underarm Odor and Excessive Sweating) | Wait required | Around 4–6 months later, once the Botox effect has faded | While the Botox effect remains, it is said to be difficult to judge how well the microwave treatment is working. It is advisable to decide the treatment plan with your doctor, including which to have first or whether to switch. |
| Surgery for Underarm Odor (Gland Excision, etc.) | Wait required | Generally assessed after the effect has worn off (a matter of months) | While the injection's effect remains, it is hard to assess the true severity of symptoms, which can affect the decision on whether surgery is needed. If you are considering surgery, it is safest to be examined by a doctor once the effect has faded. |
