What Causes Underarm Pigmentation?

Underarm darkening can happen for many reasons. It's usually harmless but can be improved with the right care and consistency.

Friction

Rubbing from tight clothing, shaving or repetitive movement.

Shaving

The razor can cause irritation, inflammation and darkening.

Deodorants

Harsh chemicals and fragrances can trigger pigmentation.

Dead Skin Build-Up

When dead skin cells accumulate, the area can look darker.

Hormonal Changes

Hormonal fluctuations can increase melanin production.

Genetics

Some people are more prone to pigmentation than others.

Underarm pigmentation is not permanent and can be improved with the right routine.
