Dark Under Arm

Naturally, your arm should be the same as your skin's remaining color. But the skin in the axes might develop a deeper color sometimes. Dark underarms are typically no indicator of seriousness but can be uncomfortable for some - particularly during the tank top and swimsuit season.

Darkening is typically linked to a skin disease known as Nigerian acanthosis (AN). In the pliers surrounding the body, it causes the skin to thicken and darken.

Everything you should know about Dark Under Arm

Acanthosis nigricans is characterized by dark underarms. People with an underlying medical condition, such as diabetes or obesity, are more likely to develop this skin ailment.

The dark tint isn’t generally a reason for worry in and of itself. Some people, however, resent having dark underarms for aesthetic reasons and may want to pursue the following treatments:

  • Restoring moisture
  • The use of topical creams
  • Undergoing laser treatment
  • Lemon juice or sea cucumber extract are examples of natural therapies.

Acanthosis nigricans (AN) can produce thickness or darkening of the skin in various parts of the body, including the neck and groin. The prevalence of Acanthosis nigricans varies according to age, race, and body weight, and it affects between 7 and 74 percent of persons.

Chemical peels cost about Rs. 1800 to Rs. 5500 on average, laser therapy costs approx. Rs. 4000 to Rs. 30000 on average, and skin lightening injections cost approx. Rs. 6000 to Rs. 40000 on average. Similarly, fairness creams can cost anything from approx. Rs. 200 to Rs. 2,000.

The extent of improvement is determined by parameters including depth, severity, and skin type. After around 6 weeks, you should notice a difference in the look of your pigmentation. This is because the immune system eventually resorbs the shattered pigmented particles.

Bleaching agents and chemical peels do not have a long-term effect. Laser treatments, on the other hand, provide a long-term option for skin whitening.

The laser therapy to brighten underarms remains the finest approach for whitening underarms. The procedure is fully risk-free and has no negative effects.


There are other possible reasons for the darkening of armpits, such as:

  • Deo and antiperspirant products (chemical irritants)

Some deodorants might irritate the skin, and you may get darker skin instead of this irritation having an outburst in other regions of the body. In that region, you are more likely to have decoloration than a rash since a bodily fold like the axis might be annoyed.

  • Razorblade (irritation and abrasion) 

Many women shave their armpits on a regular basis, therefore you may not be aware that this is the most likely source of your skin discoloration. It's possible that your razor is aggravating your skin, or that your hair is making your skin seem darker. Shaving just eliminates surface-level hair, so if your hair color is darker than your skin tone, you may notice a dark stain on your skin that is actually simply subsurface hair.

  • A build-up of dead skin cells (lack of exfoliation)

Dead skin cells are another prevalent source of darker underarm pigmentation. When dead skin cells aggregate, they color, and the underarms are especially vulnerable to muted cells. Healthline suggests frequent exfoliation to take dead skin cells off the body, so that the look of the skin is lightened if this is because of the apparent dark color. To resolve this condition, you can use a body scrub or a face exfoliate.

  • Obesity is a problem that affects many people

When you gain weight, your body becomes more resistant to the effects of insulin. This hormone aids in blood sugar control. Increased synthesis of skin pigment cells can be caused by high insulin levels in the blood. Darkening in the underarms and other skin creases affects more than half of persons who are 200 percent or more above their optimal body weight.

  • Insulin resistance

Insulin resistance affects the majority of patients with this illness. Insulin resistance refers to the body’s decreased sensitivity to insulin's actions. Insulin resistance can lead to type 2 diabetes in the long run.

  • Acanthosis Nigricans

The medical term Acanthosis Nigricans is the thickened, black patch of skin, which commonly develops in the axis and around your throat and neck. You’re going to develop thicker skin patches, brownish-gray or black. These patches are commonly visible around the collar, the axis, around the groin, and sometimes in other folds of the skin. This is frequently a symptom of obesity, diabetes, and abnormal levels of hormones.

  • Tight Clothes Cause Friction

Wearing tight clothing can produce friction between the material and your skin, which can irritate your underarms. This may result in discoloration. It is always preferable to wear loose clothing around sensitive places. It is recommended that you wear loose clothing, especially after your underarms have been waxed.

  • Infection with Bacteria

Our underarms provide an ideal environment for germs to thrive. Bacteria can be trapped in the skin of the underarms due to excessive perspiration. Excessive sweating is caused by the bacteria Corynebacterium minutissimum, and body odor is the least important symptom. However, this can lead to erythrasma, persistent infection in the deeper layers of the skin. If you suspect bacteria is causing the darkening of your underarms, see your doctor.

  • Melanosis in smokers

Smoker's Melanosis is a skin disorder caused by tobacco use. Smoking is the cause of hyperpigmentation in this case. As long as you smoke, your underarms will develop dark patches. The first step in treating smoker's melanosis is to stop smoking. It will not only help to lighten the blackness in your underarms, but it will also enable you to break a negative habit that hurts other areas of your body.

  • Hyperpigmentation 

Hyperpigmentation is a frequent, usually innocuous condition in which particular areas of the skin look darker than the rest of the body. This is due to deposits on the skin caused by excess melanin, the pigment that gives the skin its colour. It’s advisable that you contact a dermatologist and follow the drug you recommended if you feel that your arm’s darkening is caused by hyperpigmentation.

  • Addison’s disease

The illness of Addison is caused by injury to the suprarenal gland. The darkness or hyperpigmentation is one of the signs of this condition. Other symptoms of this condition include extremes of tiredness, weight loss, and decreased appetite, low blood pressure (including fainting), salt desire, low blood sugar, nausea, diarrhea, or vomiting. Abdominal discomfort, muscle or joint pain. It can affect persons of any age, even if it is most frequent between 30 and 50 years of age. In women, too, it is more prevalent than in males.

  • Hormonal imbalances

Acanthosis Nigricans is more common in those who have an underactive thyroid, polycystic ovarian syndrome (PCOS), or other hormonal abnormalities.

  • The use of medication

Some drugs, such as high-dose niacin, birth control pills, and corticosteroids, have been linked to the development of AN.

  • Cancer

A malignant tumor forming in the stomach, liver, or another internal organ might induce AN in rare situations. Malignant acanthosis nigricans is the name for this kind of AN.

Although it is not always feasible to avoid AN, there are several steps you may do to lessen your chances of acquiring dark underarms:

  • Consider using a natural bleaching agent 

Some vegetables and fruits have acidic, antibacterial, and antiseptic characteristics that help to lighten the skin naturally.

  • Apply Moisturizer 

Moisturizing your underarms at least twice a day is the single most essential thing you can do to prevent or cure dark underarms.

  • Exfoliate

Exfoliating can help to lighten the look of dark underarms produced by dead skin cells that have gathered there.

  • Start waxing 

Waxing is a great alternative to shaving. Shaving can result in dense hair under the skin, which can generate dark underarms.

  • Deodorants aren’t necessary 

Deodorant’s powerful antiperspirant ingredients typically cause an inflammatory reaction that darkens underarms.

  • Alter your eating habits

If you have diabetes, changing your diet to limit carbs and sugars may be beneficial.

  • Take the tablet no longer

Whether your skin problem is caused by oral contraceptives, you might try switching to a different method of birth control to see if it improves once the pill is stopped.

  • Put an end to the electrolysis 

When electrolysis is used to remove hair, all women, but especially those with dark skin, incur the risk of hyperpigmentation (skin darkening). If you’ve been receiving electrolysis treatments to eliminate underarm hair, you should cease them immediately to avoid further discoloration.

Although black underarms are normally safe, they should be looked out for by a dermatologist, especially if you suspect you have diabetes or a thyroid gland that is underactive. The black skin normally fades when the underlying problem is treated.

If you see dark patches beneath your arms or elsewhere on your skin, make an appointment with your dermatologist or primary care physician very once. This might indicate a more serious ailment, such as cancer.

The following are some widespread fallacies concerning dark underarms, as well as their debunking:

  • Dark underarms can be whitened using lotions 

The underarm darkening can be caused by a variety of factors, thus there are a variety of treatments available. Textural alterations may be addressed with the use of a lotion, but darkening will not be. Because the underarm is an intertriginous region with constant skin-to-skin contact, drugs placed there may have a higher potency. As a result, it’s critical to use gentle yet effective creams and treatments on this delicate skin.

  • Underarms may always be whitened by rubbing lemon or kalamansi on them 

While these natural ingredients have whitening capabilities when applied to the delicate underarm skin, they might cause allergic or irritating responses, resulting in darkening.

  • Underarm darkening is not caused by pregnancy, heredity, or other health issues

The causes of underarm darkening are several. Some people are more prone to it because of their genetic or cultural background, while others have endocrine issues like acanthosis nigricans or are pregnant.

Anyone with AN in their underarms or other parts of the body is in danger. However, some people are more susceptible to this skin problem than others.

Dark underarms can be caused by a number of circumstances, including:

  • Having a close family member who suffers from the disease
  • Having a darker complexion
  • Being overweight
  • Suffering from diabetes or insulin resistance
  • Too much shave or plucking beneath the arms
  • Having a hormonal imbalance
  • Using some prescription drugs
  • Being diagnosed with stomach, liver, or colon cancer


Treatments with therapies and lasers

Laser therapy can help to reduce skin thickness, which commonly develops in conjunction with skin darkening. Skin that has been thinned may look lighter in color.

Laser therapy may help minimize hair growth and, as a result, the need to shave.


Underarm Pixel

Deeper pigmentation inside the skin can be efficiently targeted by a laser device. This therapy is effective. The laser beam breaks down the melanin, which then fades after a few therapy sessions. To achieve effective outcomes, many sessions will be necessary. 

The laser light penetrates the skin and warms the dermis layer. This activity is immediately recognized as an injury by the body’s defense mechanism, which hurries to heal it. This procedure increases collagen formation, resulting in firmer and more elastic skin tissue. People with dark underarms should consult their doctor since skin darkening may suggest an underlying medical concern that requires quick care.

Symptoms disappear and skin lightens when the underlying problem is addressed. However, if the underlying reason is not addressed, dark underarms might return. Always seek the advice of a dermatologist, who can prescribe appropriate drugs and therapies. Never overlook a situation like this.

Topical medications

To brighten the skin beneath the arms, prescription lotions, ointments, and gels are available. These items include:

  • Retinoid creams for skin thinning and lightening
  • To lighten the skin’s hue, use hydroquinone lotion
  • Trichloroacetic acid (TCA)-based chemical peels to remove damaged skin cells
  • Dovonex (calcipotriene) is a vitamin D-based lotion that helps to decrease pigmentation
  • Bactericidal baths or topical antibiotics to relieve pain


Topical Creams: When it comes to dark underarms, the best solution is to always contact your dermatologist. Prescription lotions, ointments, and gels can be used under the guidance of a dermatologist to brighten the skin under the arms. Medicines such as retinoid creams to thin and lighten the skin, hydroquinone cream to lessen the color of the skin, a vitamin D-based cream to diminish pigmentation, and topical antibiotics or antibacterial soaps to alleviate discomfort.


Chemical Peels: To cure dark underarms, a variety of peel combinations can be employed. Chemical peels aid in skin regeneration and healing. By minimizing the appearance of hyperpigmentation and skin discoloration, a chemical peel brightens and evens out your skin tone. They refresh tired-looking skin and make it seem softer and smoother. Peels can improve the surface of your skin due to their deep exfoliating action. They can induce actual peeling of the skin, necessitating a week of rest. The end product, however, is well worth the wait.

Many physicians suggest topical lotions and antibiotics enhance the look of the underarms and minimize skin discoloration. It’s worth mentioning, however, that the creators of these items did not create them expressly for AN.

Oral medications

A dermatologist may prescribe retinoid tablets for Acanthosis nigricans that are severe or do not respond to topical therapies. Acne, psoriasis, and other skin problems are treated using retinoid tablets.

Retinoid medicines have a number of negative side effects and are not recommended for use by pregnant women. Before using these drugs for AN, people should talk to their dermatologist about the benefits and drawbacks.
