Paula's Choice non-abrasive exfoliant products are the best formulated, affordable and effective on the market. I've been using the Skin Perfecting 2% BHA Lotion for years. I regularly use this line's BHA exfoliant products twice daily - this lotion typically used at night after cleansing and toning. I use a pump and a half, at most, for my entire face and neck. The generous amount of product in stable packaging lasts me a couple months at least. This is the most moisturising of Paula's BHA creams for the face. It's soothing, I've never had an adverse reaction with this gentle product.
