In this study, the authors design a user-support system employing a smart phone for skin progress analysis. The authors’ proposed system seeks to provide user support for a skin diagnostic service employing a smart phone's camera, with the user's photograph of a skin image and continuous diagnosis of the photographed area. The cognitive user-support module recognizes the processing and the user operation of the smart phone, and transmits advice on the operation to the user in real time, via voice or text messages. In addition, the cognitive user-support module can recommend contents suitable for the user, based on the user's past situation. In the skin diagnostic service, the authors’ system provides the user with auto photography when the picture is taken, by recognizing the user's situation and guiding the user via voice or text message. The authors’ system can recommend the skin area that was used for the last diagnostic service in order to perform continuous skin diagnosis. Using the authors’ system, the user can easily take a suitable skin picture and observe the skin care progress, so that in an esthetic room, the user and beauty therapist can verify the esthetic effect by viewing the pictures taken before and after treatment.
