One reason for dark underarms is hyperpigmentation, which is a common occurrence that some people choose to ignore.

How Do Deodorants Cause Dark Underarms?

While there are several causes of dark armpits, you can take comfort in knowing that it is a common thing. Several people suffer from underarm discolouration, which is similar to the darker skin on the elbows, knees, neck or underbelly. In some cases, the darker pigmentation in underarms can also result from genetics like other skin changes.

Moreover, people with naturally darker skin are more likely to get darkened armpits as they are more susceptible to hyperpigmentation. Of course, your health also plays a large role in skin changes, but one of the most popular causes of dark armpits is using deodorants. 

Deodorants have several ingredients such as paraben, alcohol, fragrances, chemicals, etc., which can cause underarm discolouration. The reason for dark underarms is that these ingredients can cause inflammation that leads to darkening and thickening of the skin over time. Moreover, antiperspirants that help reduce sweating can clog up the sweat ducts, causing pigmentation and dress.

What Can You Do About Armpit Darkening due to deodorants?

There are several hoax remedies being taught online to lighten your armpits, such as using Baking Soda. However, you should be extremely careful before trying any such remedy as they are not medically advised and can do more damage than benefit. Ironically, some of these ingredients are generally the culprit in the list of ingredients found in a deodorant that causes hyperpigmentation as it disturbs the skin’s natural pH level. 

Alternatively, you can look into clinical treatments such as professional laser treatment, microdermabrasion, micro-needling and laser-hair reduction. There are chemical peels as well, which apparently help reduce armpit darkening. However, all these chemicals and clinical treatments can actually further irritate your skin and worsen your situation. 

Preferably you can try natural solutions that are free of chemicals and can be done easily at  home. Since we’re talking about deodorants, you might also wonder,  does roll-on darken underarms?
