DeoAce is a mild antiperspirant that can be used by people with sensitive skin.
However, some people experience itching when using the roll-on type.
Here we will introduce what to do if you experience itching and answers to frequently asked questions.
What causes itching when using DeoAce?
The ingredient used in DeoAce is aluminum chlorohydrate, which is also commonly used in cosmetics and antiperspirants.
It has a long history, having been used as an active ingredient in antiperspirants since the 1940s, and extensive research is being conducted into its safety.
It has been used since 1940, is mild to the skin, has almost no allergenic properties, and is recognized as a relatively safe ingredient.
People with metal allergies have reported itching.
We have heard from people with metal allergies that they experienced itching after using Deo-Ace.
However, although aluminum chlorohydrate is indeed a metal salt, it is said that human skin rarely experiences an allergic reaction when it comes into contact with metal.
Human skin rarely develops an allergic reaction simply by coming into contact with metal. Metal allergies occur when metal ions eluted from the metal through sweat or saliva bind to skin proteins, causing the body to recognize them as a foreign substance and trigger a rejection reaction.
In the summer, when we tend to sweat more, metals are more likely to ionize on the surface of the skin, causing many people to develop metal allergies. In addition to contact dermatitis (rash) caused by sweat, there is also systemic metal allergy, which occurs when the balance of metal ions in the body is disrupted by metals used in dental treatment or foods containing various metal elements. This type of dermatitis can occur even without direct contact with metal products, so it is also becoming known as endogenous atopic dermatitis.
Therefore, if you experience itching just by applying Deo-Ace directly, there may be another cause.
Sweat and itching are closely related, and it is difficult to pinpoint the effect on the skin.
We strongly recommend that anyone who experiences severe itching, especially in the summer when they sweat, undergo an allergy test at a hospital.
There are concerns about the various effects on the skin during the summer.
When parts of the body that are usually hidden come to the surface, it can cause strong irritation and put a greater strain on the skin.
This is the season when not only sweat but bacterial infections are particularly likely to occur, and sweating can also lead to contact dermatitis, when sebum and dirt clog the sweat glands.
If the itching continues even after you stop using DeoAce, it may be due to one of the reasons mentioned above.
In that case, try treating the inflammation with an ointment containing a steroid.
If the itching persists or the skin eczema does not subside, please seek appropriate medical treatment immediately.
You may experience itching when your sweat glands are blocked.
Aluminum chlorohydrate stops sweating by forming a gel-like film on the sweat ducts on the surface of the skin.
Because it acts relatively close to the surface of the skin, it is less irritating than aluminum chloride. However, because it still acts on the sweat glands, it may cause itching, although this varies from person to person.
Furthermore, if you use Deo-Ace on dirty skin, it may cause itching, so be sure to use it after bathing and when the skin is clean.
Enhances the skin’s barrier function
Our skin is protected from external stimuli by a mere 0.02mm thick sebum film on the epidermis.
This part functions as the skin’s barrier, but if this function is impaired by dryness or irritation, it can have a variety of effects on the skin.
If you experience itching or your skin becomes rough from sweat, strengthening your skin’s barrier function can be effective.
Prevent dryness even in summer
Summer is a humid season and people tend to sweat easily, so you may not feel that your skin is dry.
However, excessive sweating can also cause the moisture that protects your skin to be lost.
Furthermore, when sweat dries, the moisture inside the skin is also lost, causing dry skin.
Summer is a season when skin is surprisingly prone to dryness.
As you wipe away sweat more, irritation to the skin’s surface increases, causing accumulated damage, and with the effects of UV rays and other factors, it’s also a season that puts a lot of strain on the skin.
Make sure to regulate your sweat levels to maintain a moderate level, and be sure to keep your skin moisturized.
keep clean
Keeping skin clean is also important for its barrier function.
However, if you irritate your skin too much in an attempt to keep it clean, this will weaken its barrier function.
When washing your face or body, it is effective to choose a mild, slightly acidic cleanser that is gentle on the skin, and to rinse with lukewarm water instead of hot water.
After washing, be sure to rinse thoroughly so that no cleanser remains.
It’s also important to be mindful not to scrub your skin when washing or after bathing.
Make sure to keep your skin clean, keeping in mind not to irritate it.
It’s important to keep your skin cool in the summer
Itching and redness occur when the skin becomes hot or inflamed.
In the summer, in particular, when skin is prone to becoming hot, you can reduce redness and itching by using an ice pack or chilled handkerchief to cool the hot or itchy area.
If you experience itching, consult a doctor
As mentioned above, Deo-Ace uses ingredients with few reported skin irritations or allergies.
If you experience itching, first check that you have kept the roll-on container clean and that your skin is clean when you apply it.
If you still experience itching, there may be another cause.
If the itching is caused by sweat or other factors, it may eventually lead to skin irritation, so if you experience severe itching when using DeoAce, or if you continue to experience itching even after stopping use, be sure to see a doctor.
Also, depending on your skin type, DeoAce may not be suitable for you.
In such cases, please stop using it immediately.
