Skip the expensive clinic visits and ineffective beauty wands. We engineered a device your family will actually use. Delivering a visibly lifted appearance, it integrates effortlessly with your favorite skincare routines for shared, real-world results.
With over 21 million skin data points and IoT-controlled precision, 4.0DJM offers intelligent, adaptive beauty treatments.
From Düsseldorf to Shenzhen, our international R&D team invests 40% of annual profits into innovation, because beauty never stands still.
4.0DJM devices collect real-time usage and skin data, such as treatment time, intensity levels, and impedance measurements, which are securely transmitted to our cloud-based skin database. This allows us to analyze hundreds of data points per session, optimizing energy delivery and fine-tuning future product updates to match user needs.
With IoT-driven real-time impedance feedback (in our Ultrasound and RF devices), each session automatically adapts energy output for the most comfortable and effective experience. It's akin to a built-in, inch-by-inch professional technician, ensuring consistent, pain-free, and personalized treatments every time.
By embedding IoT technology into our Red Light, Ultrasound, and RF devices, 4.0DJM brings clinical-grade precision, personalization, and progress tracking into your daily routine, right from your bathroom counter, and usable by every family member.
