Start fresh – For maximum all-day protection, make sure your underarms are clean and dry before applying roll-on. If your roll-on contains antiperspirant, apply it the night before. Night-time application gives the antiperspirant time to soak into your skin’s sweat ducts and helps protect you from perspiring the next day.

Towel off – Make sure your underarms are completely dry before you apply roll-on. Your skin’s sweat glands can absorb the antiperspirant better when applied to dry skin.

Shake well – Give your roll-on a good shake to make sure the active ingredients coat the ball correctly.

Apply evenly – Swipe the ball back and forth until you’ve covered the surface of your underarm with a thin layer of roll-on. Usually, three or four strokes are just right for great coverage.

Air dry – Give your underarms a few seconds to dry before you get dressed. This extra step helps ensure that the product absorbs correctly. Always give your roll-on time to dry on your skin before you do anything active that may cause you to perspire.
