But along with discoloration if you are finding any other symptoms like the thick or velvety texture of the skin, then this might indicate some serious trouble and you have to consult a dermatologist for some help.

Causes of the Dark Underarms

Before proceeding to the treatments and remedies we might want to know the factors which are causing the dark underarms. There are some surprising things that you never imagined, are responsible for the darkening of your underarms.

The Harmful Deodorants – The skin of your underarms is delicate. Some deodorants can irritate this area developing darker skin. People with dark complexions are more prone to this issue.

The Naughty Hormones – An imbalance in the hormone secretion can cause skin discoloration, this condition is called “melasma”. This condition is most common among pregnant women or those who are under hormonal birth control.

The Side-Effects of Medicines – Some medications like nicotinic acid, insulin, corticosteroids, and diethylstilbesterol are known to cause darker underarms. But the discoloration caused by these drugs isn’t dangerous and does not denote any underlying medical problem.

The Dead Skin Cells – When the dead cells accumulate in the armpits, they increase the pigmentation process. If you do not exfoliate your underarms regularly, then it will result in dark patches because of hyperpigmentation.

The Bad Shaving – Shaving only removes the top layer of your hair. So, if your hair color is darker than your skin tone, your skin might also appear dark. Another reason is the irritation caused by the razor which leads to post-inflammatory hyperpigmentation, causing dark underarms.

The Acanthosis Nigricans – Acanthosis Nigricans (AN) is a skin condition where one or more areas of your skin darken and thicken, sometimes the damaged skin will have a velvety touch. It can happen in the underarms and other areas of the body like the back of the neck, your elbows, and knees, or even beneath your breasts. AN can also be a potential indicator of life-threatening diseases like diabetes or cancer.

The Insulin Resistance – The Acanthosis Nigricans (AN) is an early sign of Type 2 Diabetes, in which the body does not produce the required amount of insulin. In this case, your neck will be the first area to darken before your underarms. If the discoloration happens quickly along with the other symptoms of insulin resistance, contact your doctor as soon as possible.

Cancer – In rare conditions, the darker armpits symbolize cancer in the stomach, liver, or other internal organs of your body. This condition is called malignant acanthosis nigricans. The discoloration disappears once the malignant tumors are removed from the body.

Treatments to Remove Dark Underarms

Our underarms are analogous to eyelid skin, they get irritated easily and the irritation produces excess pigmentation. In addition to this, the underarms skin folds onto itself, increasing the absorption of any product applied in that area. In order to achieve some improvement without further irritation, a delicate balance is required.
Minimizing the irritation should be the priority in lightening your underarms, which can result in reduced pigmentation and the following are some of the treatments which focus on the same.

Treat your Underarm Rashes First

The treatments for lightening your dark armpits are not effective until the rashes are taken care of. A rash is the inflammation of your skin with redness, itching, local roughness, or flakiness. The possible causes of the inflammation are,

  • Psoriasis
  • Eczema
  • Fungal infections
  • Allergy contact dermatitis like nickel from deodorant

Once the issue is controlled, the whitening treatments can be started.

Use Gentle Exfoliants

The physical pressure of scrubbing is more likely to cause irritation and worsen the problem. Instead of that, use a gentle combination of chemical and physical exfoliators into your routine a few times a week. The effective ingredients of this treatment are lactic, glycolic, and salicylic acid.

Optimized Shaving Routine

Shaving without a shaving cream can cause irritation, itching, and rashes. To prevent this, use moisturizing shaving cream, and also replace your razor blades frequently to avoid the dull blades rubbing along the skin.

If you are allergic to razor blades, you can opt for waxing or laser hair removal.

Switch to Hypoallergenic Deodorants

The number of people with dark underarms is on the rise recently due to the increase in the popularity of natural deodorants. These deodorants are highly fragranced and some people develop allergies to plant-based fragrances. The Symptoms of these allergies are redness and itching. Some people experience irritation and rash from excessive sweat.

The natural deodorants consist of sodium bicarbonate which causes hyperpigmentation without any rashes. So, if you notice the darkening of your underarms after trying a new deodorant, consider replacing it with a hypoallergenic antiperspirant or a deodorant without sodium bicarbonate.

Consider Laser and Micro-needling Treatments

If the above treatments are not effective, the procedural-based approach is a better option. You can choose micro-needling or chemical peels, or laser therapy to brighten your dark underarms. But remember these procedures will require multiple visits to see significant improvement. 

Also, dermatologists do not recommend home chemical peels, because the underarms’ skin is a very sensitive area and it is best if you leave it in the hands of a professional.

Try Hyperpigmentation Serums with Caution

The regular hyperpigmentation serums which you use for your face can also be used to whiten the dark underarms. But you should be very cautious as the absorption will be greater in your armpits because of the skin folds. You can start it slowly by applying twice a week and gradually increasing its frequency every week. Apply a very thin layer to your underarms and allow it to dry before lowering your hand.
