No. syNeo 5 does not need to be applied daily. You only need to reapply it once the effect begins to wear off naturally. However, factors such as individual skin type, heavy perspiration or very warm weather may shorten the duration, meaning you may need to reapply it sooner.

Applying syNeo 5 at night allows the product to work most effectively. During sleep, the body’s metabolic activity slows down and sweat production is reduced. This creates ideal conditions for the antiperspirant to act on the sweat ducts without being washed away by active perspiration. As a result, syNeo 5 can fully develop its long-lasting effect.

No, we recommend not using another deodorant between applications of syNeo 5. Combining syNeo 5 with other products may reduce its effectiveness. Additionally, it could cause unwanted skin reactions such as burning, redness or irritation because the ingredients are not designed to work together.
If you would still like to add a fragrance, you can apply an eau de toilette or perfume to other areas of the body, such as the neck, wrists or chest. Since syNeo 5 is fragrance-free, it will not interfere with your perfume.

Yes. syNeo 5 works from the first application. Unlike many other antiperspirants, it does not need to be applied repeatedly before you notice an effect.

Yes, the effectiveness of syNeo 5 may vary slightly, even when the instructions are followed carefully. Like the rest of the body, the skin is influenced by various factors.
External conditions such as temperature or humidity, as well as lifestyle factors like stress, caffeine, nicotine, alcohol or spicy foods, can affect sweat production. Hormonal changes may also influence how strongly the product works.
After several weeks of use, the skin may also adapt to the product. This can slightly reduce how easily syNeo 5 enters the sweat ducts. If this happens, it can help to extend the time between applications by one or two days. This gives the skin time to return to its normal state so the next application can work effectively again.

You can support the effectiveness of syNeo 5 by applying it after a hot shower, bath, or steam bath. The warmth helps open the skin’s pores, allowing the product to absorb more effectively into the sweat ducts.
If your skin tolerates the product well, it can also be used at shorter intervals. However, more frequent application may increase the risk of skin dryness, redness, or irritation.
It is also important to note that daily use does not necessarily improve the effect. In some cases, applying syNeo 5 too soon after the previous application may reduce its effectiveness, as the sweat gland openings may still be temporarily reduced. For best results, it is usually better to allow enough time between applications.

Highly concentrated aluminum chloride hexahydrate solutions, such as ones available in pharmacies or prepared at home, can often cause skin irritation, redness or inflammation.
syNeo 5 uses a carefully balanced combination of active ingredients to reduce this risk. In addition to aluminum chloride hexahydrate, it also contains dialuminum chloride pentahydroxide, a milder compound that helps achieve strong effectiveness while remaining gentler on the skin.
The formula is further supported by skin-conditioning ingredients such as glycerin, propylene glycol, and allantoin, which help improve skin tolerance. Thanks to this balanced formulation, skin irritation occurs much less frequently.

Yes, syNeo 5 can also be used on the palms of the hands. However, because the skin on the palms differs from underarm skin, the effect and duration may be shorter.
In general, syNeo 5 can also be applied to other areas of the body. Some customers report positive results when using it on areas such as the back, buttocks, the back of the knees, or the face. However, the duration of the effect may vary depending on the area and individual skin type.
When applying syNeo 5 to new areas, we recommend starting with a small amount to test your skin’s tolerance. Avoid contact with the eyes and nasal passages.

No. syNeo 5 does not stop the sweat glands from working. It temporarily reduces the size of the sweat gland openings so that less sweat reaches the skin surface.
This does not interfere with the body’s natural temperature regulation. The underarm area represents only a very small portion of the body’s skin surface, so reducing sweating there does not affect the body’s ability to cool itself.
Body odor occurs when sweat on the skin is broken down by bacteria. syNeo 5 also helps inhibit the growth of these bacteria, which helps prevent unpleasant odor.

Shaving can slightly irritate the skin and open the hair follicles. Because syNeo 5 contains active salts, applying it immediately after shaving may cause a stronger burning or stinging sensation. For this reason, we recommend not applying syNeo 5 on the same day you shave.
Ideally, apply syNeo 5 1–2 days before shaving and/ or 1–2 days after shaving. This gives the skin enough time to recover and helps reduce the risk of irritation.
Compared with many deodorants that must be applied daily, syNeo 5 is often gentler for shaved underarms because it does not need to be used every day.

Shaving underarm hair can help improve odor control. Underarm hair can trap sweat and provide a larger surface for odor-causing bacteria to settle and grow. It can also slow down the evaporation of sweat.
Removing the hair does not reduce sweat production itself, but it allows syNeo 5 to be applied directly to the skin. This can help the product reach the sweat ducts more effectively and allows for a more even and controlled application.

syNeo 5 is generally well tolerated, as it does not contain perfumes or essential oils, which are common triggers for skin irritation and allergies in many deodorants.
However, if you have neurodermatitis or very sensitive skin, your skin may react differently. If you know that you are sensitive to alcohol or any of the ingredients, you should avoid using the product. Because syNeo 5 does not need to be applied daily, the overall exposure of the skin to the product is typically lower than with many conventional deodorants.
If you have particularly sensitive or allergy-prone skin, it may be helpful to consult a doctor before using syNeo 5 or to test the product on a small area of skin first.

syNeo 5 has been available in several European countries since 1995 and is generally known for its good skin tolerance when used as directed.
The formula does not contain perfumes or essential oils, which are common triggers of irritation or allergic reactions in many deodorants. In addition, syNeo 5 has been dermatologically tested by independent institutes and rated as having very good skin compatibility.
However, individual sensitivities to certain ingredients can never be completely ruled out. If you have particularly sensitive skin, we recommend testing the product on a small area of skin first.

Regular use of syNeo 5 can lead to a noticeable reduction in sweating for many users. Over time, some people report that perspiration becomes less intense even between applications. However, results can vary from person to person, and a permanent reduction in sweating cannot be guaranteed.

Many people who struggle with excessive sweating find that regular deodorants or antiperspirants do not provide lasting results. In some cases, products may work only briefly or lose their effectiveness over time.
syNeo 5 was developed to address this problem with a carefully balanced formula and a defined concentration of active ingredients. The product works by reducing the size of the sweat duct openings, which helps limit the amount of sweat reaching the skin’s surface without blocking the glands completely.
Because of this controlled effect and the recommended application intervals, syNeo 5 can maintain its effectiveness over time for many us

No. syNeo 5 is not intended to treat athlete’s foot and is not a substitute for medical antifungal treatments. However, some users report that their feet feel drier when using syNeo products. Since moisture can contribute to the development of athlete’s foot, reducing sweat may provide some indirect benefit.

syNeo 5 acts only on the surface of the skin and within the sweat ducts. It is not intended to penetrate deeper layers of the skin or enter the bloodstream.
The product has been dermatologically tested and its ingredients comply with European cosmetic regulations, where they have been safely used in cosmetic products for many years. Because syNeo 5 does not need to be applied daily, overall exposure to the product is typically lower compared with many conventional deodorants.
If you are pregnant or breastfeeding and would like additional reassurance, we recommend consulting your doctor before use.

We recommend using syNeo products only for children aged 10 years and older. Application should be supervised by an adult to ensure correct use and to avoid contact with the eyes or mucous membranes. From the age of 13, syNeo products can generally be used independently.
If your child has particularly sensitive skin or specific health concerns, it may be helpful to consult a doctor before use.

syNeo products have a shelf life of at least 30 months when stored properly (e.g., in the bathroom, away from direct sunlight and at temperatures below 25°C / 77°F). For this reason, a specific best-before date is not required under cosmetic regulations.

The 7-digit batch number indicates the production details:

• First 3 digits: production day
• Next 3 digits: bottling day
• Last 2 digits: production year

This information allows you to determine when your syNeo product was manufactured.

A slight cloudiness in syNeo 5 may occur if the product has been stored for a longer period or under unsuitable conditions. This is normal and does not affect the product’s effectiveness.

In rare cases, crystallization of ingredients in syNeo 5 may cause the pump or spray head to become clogged. If this happens, remove the spray head and rinse it with warm water. You can also gently clear the riser tube with a thin object, such as a bent paper clip, until the liquid begins to flow again. Then reattach the spray head
