A multifunctional, adaptive facial mask delivers cosmetic massage and light therapy in a hands-free format. The mask integrates three elements: (i) internal motion-guiding contours that channel tactile stimulation along anatomically relevant lymphatic paths, (ii) zone-selective actuation using vibration nodes, inflatable micro-bladders, or oscillating pads, and (iii) a flexible Light-Emitting Diode (LED) grid delivering red, near-infrared, and optional blue wavelengths. The soft, medical-grade silicone shell conforms to diverse facial anatomies and maintains a continuous smooth surface that isolates the user from hard mechanics. A microcontroller sequences stimulation across zones (forehead, temple, cheek, nasolabial, jawline, and neck strap) to emulate facial-yoga strokes and lymphatic drainage. Preset modes such as Lift, Recovery, and Glow manage timing, direction, and intensity. Optional enhancements include gentle heat, removable cooling inserts, and low-frequency micro-stimulation. The mask provides an integrated combination of guided internal geometry, sequenced hands-free actuation, and cosmetic light therapy within a flexible, inclusive design.
