Home beauty devices are built for one region or the other: facial devices for the face, scalp devices for the scalp. DIVE 4-WAY PRO changes heads instead. A patented magnetic mount takes four facial heads — RF lifting, an ionsono booster combining galvanic current with 1 MHz ultrasound, red and infrared LED, and a galvanic mask connector — and a scalp head whose comb tips reach the scalp through hair. One body, both regions. Its modes are validated for general use, which is what keeps them safe. The app tells the user which head to attach today, then personalises the recipe inside that head: a neural network on the phone reads six skin metrics and scalp condition, and the result is one five-minute session. After each session the system learns how that skin responded.
