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.

While primary lymphedema is rare, numerous cancer patients develop secondary lymphedema, or the retention of lymphatic fluid. Lymphedema is characterized by progressive, irreversible fibroadipose tissue deposition. Non-surgical approaches such as compression therapy are the most common strategies to address lymphedema but are inadequate in the long term. Surgical procedures can reconstitute lymphatic drainage, but this approach is not curative. A new approach is needed to mitigate fibroadipose tissue deposition in lymphedema.
