Best Soap for Dark Neck and Underarms

Finally find out how to get rid of dark underarms and what is the best soap for dark neck and underarms so you can raise your arms high and wear tank tops again without hesitation!

Dark spots under the armpits and on the neck can be a really ugly sight, and many people are not even aware of how noticeable they can be. And is, in addition to discomfort, dark skin under the armpits a cause for concern? Or is it just a cosmetic problem? Find out all that and more through our text.

Best Soap for Dark Neck and Underarms

1. Shaving

Shaving can cause the appearance of dark skin under the armpits in two ways. First, when we shave hairs, we only remove their surface part. And what about the part that remains under the skin? You guessed it! If the hair under your armpits is dark and quite thick, then after shaving you will be left with a bunch of black dots under your armpits, which can look like a big dark spot from a distance.

But that’s not the only way shaving contributes to underarm hyperpigmentation. Razor irritation leads to hardening of the skin and it can become rougher and darker. Also, this process of hair removal triggers in some people the increased activity of melanocytes – cells that create dark pigment, and thus the appearance of spots under the armpits.

In short, frequent shaving causes hard and dark skin because these procedures lead to skin irritation. Waxing is a better solution because it pulls out the hair from the roots, although it is a painful procedure that is not easy to decide on.

2. Deodorants and Antiperspirants

Deodorants and antiperspirants are our best friends when we want to prevent sweating, especially for those who suffer from hyperhidrosis.

And did you know that they can be the cause of dark spots under the armpits?

Oh yes, they can! Primarily because they contain a lot of chemicals that can irritate the skin in this way. There is a debate about whether antiperspirants cause breast cancer, but it is good to know that they can also lead to these changes in the form of spots. This is just one more reason to try out the protection a natural deodorant can provide.
The best and most commonly used natural deodorant is to apply baking soda to the armpits. This way you will avoid exposure to chemicals found in deodorants.

3. Tight Clothes

There are glands under the armpits, which makes them a very sensitive area, so the friction of clothes and skin can cause discoloration in that area. During sports and on warm days, it is better to wear loose clothing that does not stick directly to the skin.

Tight clothing can cause skin irritation. It constantly rubs and irritates the sensitive skin of the armpit, which will find its defense mechanism in the fact that it becomes rough, thickens, and darkens in that place. And even if the clothes are synthetic, in which sweating increases, the chances of getting “wonderful” black spots under the armpits are higher.

Of course, there are also situations when the small fibers of some clothes accumulate under your armpits, so here is another way that clothes can contribute to the problem.

4. Dead skin cells

The skin is an organ, although we often forget about it. The largest organ in our body. An organ that gives them the ability to regenerate regularly. It does this by shedding dead skin cells, under which new cells form. If these old cells accumulate in one place (and the armpit is an ideal place for this), then the skin can darken.

How to get rid of dark spots under the armpits in this case? Simple – exfoliating the body during the shower solves the problem.

5. Bacterial infection

Do you know why underarm sweat has an unpleasant smell? Sweat itself is not as scary as the presence and activity of bacteria under the armpits. The moist environment created by sweating favors the development of bacteria.

A bacterium named Corynebacterium minutissimum develops especially in the folds of the skin and manifests itself by creating small lesions on the skin that form red spots under the armpits (or other folds) or brown spots. This condition is called erythrasma.

6. Uric acid

Uric acid or uric acid is found, among other things, in sweat. If the skin is exposed to the action of this acid and its enzymes for a long time, there will be changes in the skin in the form of dark spots under the armpits. People who sweat excessively are especially susceptible to this. Regular removal of residues of this acid and regular hygiene is imperative here!

7. Smoking

Smoking is harmful in many ways, and in this context we will mention it as a potential cause of dark skin in the armpits and neck area. In this case, we are talking about a condition called smoking melanosis. It manifests itself as hyperpigmentation, but it is caused by smoking.

8. Bacterial infection

The underarm area is a perfect habitat for bacteria. Excessive sweating can cause bacteria to remain in the skin under the armpits. The bacterium Corynebacterium minutissimum causes excessive sweating, and the least serious problem is body odor. However, it can also cause a chronic infection in the deeper layers of the skin called erythrasma. If this is the cause, the doctor will prescribe a specific cream.

9. Melasma

Melasma is a common skin problem. It is usually seen as dark spots on the skin. It appears mainly on those parts of the body that are exposed to the sun. Women are more likely to get melasma than men. This is also common during pregnancy because hormones in that period cause melasma in women. The most common treatment is to apply sun protection to the skin at regular intervals. If it doesn’t seem to fade, see a doctor and follow steps to recover from this skin problem.

10. Addison's disease

It occurs when the function of the adrenal gland is impaired. One of the symptoms of this disease is the appearance of hyperpigmentation. Other symptoms of the disease include extreme fatigue, weight loss and decreased appetite, low blood pressure (even fainting), salt cravings, low blood sugar (hypoglycemia), nausea, diarrhea or vomiting, abdominal pain, muscle or joint pain, irritability, depression, hair loss or sexual dysfunction in women.

It can affect people of any age, although it is most common between the ages of 30 and 50. It is also more common in women than in men.

Best Soap for Dark Neck and Underarms If You Have Hyperpigmentation

Pure Kojic Acid Skin Brightening Soap for Hyperpigmentation and Dark Spots

Pure Kojic Acid Skin Brightening Soap for Hyperpigmentation, Dark Spots (Maximum Strength) 5.3 oz

Hyperpigmentation, dark spots and scars often stand in the way of glowing and healthy skin. The skincare world is full of ingredients that work to lighten the skin and complexion, the most popular of which is vitamin C. But apart from that, perhaps one of the less talked about acids has flown under the radar – kojic acid derived from mushrooms found in East Asia and fermented soy and Japanese sake rice wine, and works by preventing excessive pigment formation and reducing the visibility of existing discoloration on the skin.

This active ingredient acts as a chemical peel, lightens and evens out the complexion, and acts on skin spots and scars. It is often mentioned in the context of acne treatment, which can prevent or slow down their formation and appearance.

Products with kojic acid, among which the aforementioned soap is the leading one, remove existing hyperpigmentation spots by chemical peeling, and then prevent the formation of new ones by suppressing the enzyme tyrosine, which is responsible for the production of melanin in the skin. . And due to its antibacterial properties, it prevents acne and irregularities.

The greatest effectiveness of kojic acid has so far been seen in evening out the complexion and minimizing unwanted hyperpigmentation, and it also contains properties to reduce inflammation, and can help restore skin cells from the harmful effects of UV rays, pollution and oxidative stress. Kojic acid is intended for skin that has been damaged by the sun, has hyperpigmentation spots and can serve as an alternative choice for those who cannot use other ingredients that lighten the skin.

Although it has a beneficial effect on the skin, kojic acid should be introduced gradually, and sensitive skin could react to it in the form of slight redness. When using kojic acid, additional caution is required when exposed to the sun and mandatory use of SPF protection, as the skin is sensitive to UV rays and prone to additional irritations.

Best Soap for Dark Neck and Underarms for Dry Skin

Hyaluronic acid soaps can give results instantly, but only when it comes to the surface part of the skin. So, you can expect an impression of freshness and radiance almost immediately.

Dark Neck and Underarms Explained (Acanthosis Nigricans)

Acanthosis nigricans is the name for dark spots on the skin that can appear on the neck, under the armpits or in the groin. Sometimes they are accompanied by itching, while most of the time they appear on their own, without other symptoms. They can be a sign or consequence of a condition or disease, so it is necessary to seek the help of a doctor.

Acanthosis nigricans is not treated, because it is not a disease, but a symptom. The source of this problem should be discovered and then treated. Spots can be an indication that something is happening in the body, and on the other hand, it can be a completely harmless phenomenon.

How to recognize acanthosis nigricans

This phenomenon can be recognized by dark spots, i.e. skin pigmentation disorder. The spots are dense and that part of the skin will be rough, and itching or an unpleasant odor may also occur. Sometimes they can be a symptom of a disease such as diabetes, and in most cases they will disappear by treating their cause. Acanthosis nigricans can appear under the armpits, on the back of the neck, on the groin, elbows, knees, mouth, palms or under the breasts in women.

Cause of acanthosis nigricans

These changes in the skin occur when the epidermal cells of the skin begin to multiply too quickly, and this most often occurs due to high levels of insulin in the blood. In rare cases, this can occur due to medications, birth control pills, low thyroid hormone levels, or other medical conditions.

People who are obese, have a family history of acanthosis, or those who already have diabetes are at increased risk of developing this skin condition. Some people will be born with this condition and it is a harmless problem for them.

How is acanthosis nigrican diagnosed

When you notice spots on your skin that won’t go away, it’s best to see a doctor. To determine whether these spots are genetically inherited or are still a sign of disease, the doctor can perform a series of tests.

First of all, check whether it is insulin resistance, which can be seen in the blood. In rare cases, they will ask for a biopsy of that part of the skin.

How is acanthosis treated

Although there is no cure for these stains, you can apply creams or use the soap that we have mentioned that will reduce their appearance. When acanthosis nigricans occurs as a result of a disease, it will most likely resolve when the disease is brought under control. What can be done to prevent its occurrence is to pay attention to diet and exercise to avoid obesity.

When the changes occurred due to taking new drugs or supplements, you should stop taking them. A person with diabetes is treated for diabetes, and attention should also be paid to the diet. To improve the condition of the skin, various creams or oils such as urea, vitamin D or salicylic acid can help.
