Depends: Depending on your ethnicity, skin irritation and inflammation may darken or lighten the skin. A reaction to your underarm deodorant may be causing a problem. Try a hypoallergenic deodorant or just baking soda and see what happens. The darkening may be do to a specific skin condition or generalized disorder that requires a doctor's attention.
