We're obsessed with the Underarm Bar because it transforms the experience of using natural deodorant. The combination of charcoal, apple cider vinegar, and sea salt creates a sensorially fresh start to each day, helping to naturally fortify underarm protection in the most refreshing way.
Maximize the bacteria-eliminating power of the charcoal bar soap, lather the bar massage in the underarm area for 20 to 30 seconds on each side. If you have underarm hair, massage for 30 seconds. For best results, let the rich lather sit on the underarms for 30 seconds.
