Oy is new and Belgian and was developed by Inge Louf, a pharmacist who single-handedly looked for a solution for the unpleasant odor of her sons' sports shoes. About 4 years and 271 attempts later, she came up with Oy, a series of products that gently tackle sweat odors by neutralizing the activity of the micro-organisms that cause odor. Leave this Deo Scrub on dry skin for a minute, then moisten the skin, which converts the transparent scrub gel into a milk that also nourishes the skin. Finally, rinse and dry thoroughly. The result? No less than 24 hours of sweat odor without deodorant. Moreover, this prevents ugly circles from appearing on clothing. We are fans!
