When the weather gets warm, the tank tops and swimsuits come out -- as do the razors, tweezers and hot wax. Women go to great lengths to look smoother and sexier during the summer, and that includes shaving those underappreciated underarms.
Of course, skin problems can arise when people shave. The most common underarm skin issues are the bumps and discoloration that usually come from shaving. Doctors call those unsightly, irritating red bumps folliculitis, which is an infection of the hair follicles [source: Mayo Clinic].
