When buying produce it was listed as: Dermalogica Professional size Skin Prep Scub, which is 6 ounces. However, when paying for product it showed 2.5 fluid ounces. I thought maybe this was incorrect & as the product expensive (what price would be if 6 ounces) it really was the professional size. Boy was I disappointed it was the small size & I paid way too much. The product should be advertised as delivered & paid for. User's recommendation: Really pay attention when completing order.
