  • To lighten your dark underarms, mix a tablespoon of baking soda with enough water to form a thick paste. Gently apply and massage it onto your underarms in a circular motion, allowing it to exfoliate and cleanse those dead skin cells away. Rinse it off after 5-10 minutes with lukewarm water, and you’ll notice a difference over time.
  • For an all-natural and simple way to exfoliate your skin, add a tablespoon of baking soda to your bath water. The fizzy sensation will help loosen up dead skin cells and leave your skin feeling soft and refreshed.

  • If you’re in need of a natural teeth whitener, simply sprinkle some baking soda on your damp toothbrush and brush your teeth for about a minute. Rinse and follow up with your usual toothpaste. 

What Causes Dark Underarms?

Chemical irritants found in deodorants and antiperspirants might be playing a role in creating that unwanted darkness.

These products can sometimes cause skin irritation, leading to a buildup of dead skin cells that make your underarms appear darker.

Next, we’ve got shaving – a seemingly harmless activity that most of us do on a regular basis.

The friction and abrasion caused by shaving (or wearing a sleeveless shirt) can actually contribute to dark underarms. When you shave, your skin can become irritated and discolored over time.

The accumulation of dead skin cells is another factor that can cause dark underarms. Your underarm skin is constantly exposed to various elements, and these dead skin cells can build up, leading to a darker appearance.

To keep your underarms looking fresh and light, make sure to exfoliate regularly to remove this buildup.

Obesity can actually be a leading cause of dark underarms. When you lose weight, you may notice that the darkness in your underarms starts to fade.

This is because weight loss can help improve circulation and reduce friction in that area.

Why Does Deodorant Make Your Armpits Dark?

Deodorant is a big part of personal hygiene routine, used to help neutralize body odor. While it is necessary to maintain good hygiene, using the wrong kind of deodorant or not following proper application instructions can result in dark patches on your underarms.

This darkening happens due to a combination of ingredients which may lead to residue or a mixture left on your skin when you apply it, leading to discoloration over time. 

The main ingredient in most store-bought deodorants is aluminum, which helps reduce perspiration and block sweat ducts from releasing moisture onto the skin.

Aluminum chloride mixed with other compounds form a reaction with your sweat glands that temporarily blocks them from secreting sweat and producing odor.

However, when applied too heavily it can leave extra product around the skin’s surface which will eventually build up and cause darkened underarms. 

Some people are also sensitive to certain fragrances and ingredients found in common antiperspirants such as alcohol, baking soda, talcum powder or propylene glycol, all of which can cause irritation and inflammation resulting in discoloration.

Make sure you pay attention to what type of product you’re applying under your arms because this could be causing the dark patches due to frequent use or wrong kind of product for your skin type.



Baking soda is an incredibly versatile ingredient. It has many different benefits and uses when it comes to skin care, including helping lighten dark underarms.

To achieve the best results from baking soda, combine it with other ingredients such as lemon juice or apple cider vinegar for an extra boost of lightening power.

Baking soda is not a scientifically proven method of whitening the underarm area; however, there are many reports of people successfully using it as a natural remedy.

If you’d like to try baking soda for this purpose, be sure to patch test first and keep your armpits clean and dry at all times.
