How to Care for Your Underarms in 3 Simple Steps

Discoloration

Underarm hyperpigmentation, excessive darkening or changes of the skin can be caused by a few things. Overexposure to UV rays can stimulate and produce brown-colored pigment, and hormonal changes and allergic reactions to products can also contribute. Underarm hair tends to be dark and coarse, which gives off the appearance of a shadow because the stubble sits just below the surface of your skin. Waxing can help prevent this shadow if it bothers you as well.
