No one wants to walk around with embarrassing underarm stains. If sweating is a problem that has become hard to control, turn to Certain Driproducts, like its Antiperspirant Roll-On. This clinical strength product contains aluminum chloride compounds, which work to block pores and inhibit the release of sweat. That’s the same ingredient you’ll find in products available only via prescription. When used regularly, Certain Dri can provide sweat and odor protection for up to 72 hours. This water-based, colorless, odorless product is gentle on skin and won’t wash off in the bath or shower. Sufferers of hyperhidrosis can rely on the Certain Dri Protection System for the relief they need. Certain Dri recommends customers apply the product at bedtime several nights a week for best results.
