Your underarms should naturally be about the same shade as the rest of your skin. But sometimes, the skin in the armpits can turn a darker hue. Dark underarms usually aren’t a sign of anything serious, but some people may find them embarrassing. Darkening is often due to a skin condition called acanthosis nigricans (AN). It causes the skin to thicken and darken in folds around the body. Unless you're one of the lucky girls who doesn't sweat or have body odour, deodorant is probably a staple in your daily routine. However, it can make your underarms darker if it contains harmful ingredients, or if it doesn't work well with your skin. While deodorants are less likely to cause hyper-pigmentation compared to shaving and genetics, you should watch out for the following ingredients in your stick:
If your deodorant has alcohol, it's more likely to dry out your underarms and cause friction, which in turn will make your skin thicker and darker. Yikes!
PARABENS AND ALUMINIUM CHLORIDE
They are common allergens found in skincare products, including deodorants. Parabens (a type of preservative) and aluminium chloride (an ingredient that inhibits sweat production) can cause redness, swelling, itching, and hives, which can lead to hyperpigmentation.
