I’ve been saying for years never to use a washcloth because it can be irritating. The same holds true for hand held cleansing devices. I tried a few of them recently and while I do have to admit that they are quite fun to use, the irritation they present is unwelcome when it comes to acne-prone skin types. If you want exfoliation and like how a hand held device physically exfoliates, a better option is chemical exfoliation. 10% alpha hydroxy acid will exfoliate without the irritation and will improve the texture of acne-prone skin. My strong advice: leave cleansing to bare hands, and never use a device, washcloth or otherwise, to wash.
