SCAR is a digital healthcare innovation that integrates AI-powered dermatological diagnosis, targeted therapy, and personalized visual recovery into one smart, non-invasive device. Utilizing a CNN algorithm trained on large-scale dermatological image data, it classifies scar types with clinical accuracy and delivers treatment via a piezoelectric microdispensing system capable of 10–300pL dosing without thermal damage. An embedded RGB LED ring provides photobiomodulation (630/520/470nm) to support skin regeneration. Its modular design enables seamless transitions between diagnostic (REMED), therapeutic (CURE), and aesthetic (BEAUTY) modes. The device supports BLE 5.0 app connectivity and OTA firmware updates for remote management and scalability. SCAR addresses not only physical skin damage but also emotional recovery, empowering patients with restored skin function, tone harmony, and self-confidence. It represents a new paradigm in connected wound care and digital dermatology.
