What is Perspirex? Effects and How to Use This Deodorant for Hyperhidrosis and Body Odor

Are you hesitant to wear light-colored clothes due to sweat stains, or do your hands get sweaty, dampening documents? Hyperhidrosis and osmidrosis are often not fully addressed by over-the-counter deodorants. Perspirex is a medical-grade antiperspirant that physically suppresses sweating by "capping" the sweat glands themselves, differing in mechanism from commercial products that temporarily mask sweat and odor. This page provides a detailed explanation of how Perspirex works, its proper usage, reasons why it might not seem effective, and potential side effects.

  • ✓Aluminum chloride forms plugs within the sweat glands, physically suppressing sweating itself (unlike temporary masking seen in over-the-counter products).
  • ✓There are three types—Original, Strong, and Comfort—that can be selected according to skin sensitivity and the desired level of effect.
  • ✓The basic usage is to apply it before bed, and once it takes effect, you can maintain it with 2-3 applications per week.
  • ✓Can be used not only for underarm hyperhidrosis, but also for hyperhidrosis of the palms and soles of the feet.

Do you worry about sweat stains, making you hesitant to wear light-colored clothes? Are underarm odors a concern, making you uncomfortable getting close to people? If over-the-counter deodorants aren't enough for your sweat and odor problems, Perspirex offers a medical-grade solution.

What is Perspirex?

Perspirex is a medical-grade antiperspirant from Denmark. Its active ingredient, aluminum chloride, reacts with water in the sweat glands, forming a plug deep inside the gland to physically suppress perspiration.

Unlike commercial deodorants that mask sweat and odor, Perspirex creates a "seal" in the sweat glands to suppress sweating itself, making its effects long-lasting.

Three Types of Perspirex

Type Features Recommended for
Original Standard strength. For first-time users. Those concerned about sweat and odor, first-time Perspirex users.
Strong More powerful antiperspirant effect. Those who found Original ineffective, those with severe hyperhidrosis symptoms.
Comfort Low-irritation formula for sensitive skin. Those with sensitive skin who found Original irritating.

Target Areas

  • Underarms (Axillary hyperhidrosis, body odor)
  • Palms (Palmar hyperhidrosis)
  • Soles of feet (Plantar hyperhidrosis)

Are you experiencing these symptoms?

Symptoms of Hyperhidrosis

  • Excessive sweating in the underarms, palms, and soles of the feet.
  • Unstoppable sweating even when not nervous.
  • Clothing getting wet from sweat, causing concern.
  • Concerned about hand sweat and underarm sweat in front of others.

Types of Hyperhidrosis

Type Features
Primary Focal Hyperhidrosis Excessive sweating in specific areas (underarms, hands, feet, etc.). Often idiopathic.
Secondary Hyperhidrosis Caused by other medical conditions (e.g., hyperthyroidism) or medication side effects.
Generalized Hyperhidrosis Excessive sweating all over the body. Requires investigation into internal medical causes.

About Body Odor (Bromhidrosis)

Body odor (bromhidrosis) occurs when sweat secreted by apocrine glands in the underarms is broken down by skin bacteria, producing a distinct smell. It often co-occurs with hyperhidrosis, and the more sweat, the stronger the odor tends to be.

Consult us if:

  • You choose clothes based on underarm sweat and odor concerns.
  • You feel anxious about being close to people.
  • You don't feel commercial deodorants are effective.
  • You are bothered by severe hand and foot sweat.

How to Use / Dosage

Basic Usage

  1. Apply Perspirex to the desired area before bed.
  2. Allow the applied area to dry completely before dressing.
  3. The next morning, wipe the applied area with a sweat sheet or damp towel (no need to reapply).

Usage Schedule Until Effect Appears

Period Frequency of Use
Until effects appear (approx. 1 week) Apply every night
After effects start to appear 2-3 times a week
For sensitive skin (2 weeks) Apply every other day

Applying before bed is most effective as sweat gland activity decreases at night.

If you feel Perspirex is not working

If you're using Perspirex but don't see results, the following could be reasons:

Usage-related reasons

  • Sweating before application (sweat glands are open, making it difficult for plugs to form) → Apply after showering/bathing when sweat has subsided.
  • Insufficient application → Apply thoroughly, not just thinly and evenly.
  • Not applying every night → It's important to continue every night until effects appear.
  • Dressing immediately after application → Wait until completely dry before dressing.

If the type is not suitable

If Original is not effective enough, consider switching to Strong.

If hyperhidrosis is severe

For severe hyperhidrosis that Perspirex cannot manage, other treatments such as Botox injections are options. Feel free to consult us via official LINE.

Side Effects and Precautions

About Side Effects

No severe side effects have been observed. However, depending on skin type and condition, the following symptoms may occur after application:

  • Redness, itching, irritation

If you notice any abnormalities, stop use immediately and consult us.

Precautions

  • Perspirex contains ethanol, so individuals with alcohol sensitivity should use with caution.
  • Avoid using on broken or inflamed skin.

よくある質問

Frequently Asked Questions

Q How long does it take for Perspirex to work?
A

Many users notice results in about a week with nightly application. Once the desired effect is achieved, you can maintain it with 2-3 applications per week.

Q What should I do if it doesn't work?
A

Please check if the perspiration has subsided before application, if you are applying it before bedtime, and if you are continuing to apply it every night. If the original formula is not effective enough, you may consider switching to the strong version. Please contact us for more details.

Q Is it effective against body odor?
A

Yes, reducing perspiration can help alleviate the odor of armpit odor. However, since there is no direct action on the apocrine glands themselves, severe cases of armpit odor may require different treatment methods.

Q How do I choose between Original, Strong, and Comfort?
A

We recommend the Original for first-time users. If the Original is not effective enough, we recommend Strong; for those with sensitive skin, Comfort is suitable. You can also consult with us during your examination.

Q Do I have to use it every day?
A

For about the first week, you need to apply it every night until it starts to take effect. Once it starts working, you can maintain the effects by applying it two to three times a week.

Q Does using Perspirex (an antiperspirant) cause breast cancer?
A

Currently, there is no definitive scientific evidence confirming that antiperspirant use causes breast cancer. Major cancer research institutions both in Japan and overseas also state that a causal relationship between the two has not been shown. While there is no need for excessive worry, if you notice any changes such as lumps or pulling sensations in your armpit or breast, please consult a breast surgeon. Regardless of antiperspirant use, early detection through regular screenings is most important for breast cancer.
