The Skin Type Solutions (STS) mobile app is a patient engagement tool that encourages patient compliance by easily accessing their customized STS Skincare Regimen. The app is designed to allow new and existing STS patients to complete the STS Questionnaire to determine their Baumann Skin Type. Once the STS Provider prescribes the patient a customized STS Skincare Regimen during the office visit, the STS Skincare Regimen is viewable through the app and allows patients to easily access and purchase/refill prescribed skincare products instantaneously directly from their STS Provider.
