Monserrat has been using the Total Nonscents Brightening Roll On by DERMAdoctor for a few days now and has noticed some positive effects. This antiperspirant not only helps to brighten the underarms and reduce discoloration, but it also provides effective sweat and odor control. The rollerball application makes it easy to apply and it dries quickly. Monserrat has experienced a decrease in sweat since using this product, which is especially beneficial for light work days. However, it may not be suitable for intense workouts at the gym. Monserrat is particularly excited about the sweat control and is looking forward to seeing if it will also lighten their underarms. Overall, the Total Nonscents Brightening Roll On seems to be a promising option for those seeking underarm brightening and sweat control.
