Washing your body removes dead skin cells and oils that could clog pores.
Heat and Humidity

As acne on arms can be resulting from clogged pores, washing your skin regularly may prevent acne.
Be sure to use gentle, nonabrasive soap that doesnt have any alcohol in it.
Try not to touch the affected area.
