Why Do Underarms Get Dark?

Before we dive into the toothpaste solution, it’s essential to understand why underarms get dark in the first place. Here are some reasons why:

Shaving: Shaving is one of the primary causes of dark underarms. When you shave, you remove the hair from the surface, but the roots remain underneath, making the skin appear darker.

Deodorant: Using deodorants or antiperspirants that contain harsh chemicals can also darken your underarms.

Dead Skin Cells: When you don’t exfoliate your underarms regularly, dead skin cells accumulate and make the skin look dull and dark.

Friction: Wearing tight clothes or fabrics that don’t breathe can cause friction and lead to darkening of the underarms.

How Can Toothpaste Help?

Toothpaste is a common household item that can be found in almost every bathroom cabinet. It contains mild abrasives that can help exfoliate the skin, removing dead skin cells that cause darkening. Additionally, toothpaste has antibacterial properties that can help fight odour-causing bacteria in the underarms.

Using toothpaste for dark underarms is an inexpensive and effective solution that can help brighten up the area.

Step 1: Choose the Right Toothpaste

Not all toothpaste is created equal, and you need to choose the right one to get the best results. Look for toothpaste that contains baking soda, hydrogen peroxide, or charcoal as these ingredients are known for their whitening properties.
