Emface is BTL's needle-free facial lifting and tightening device that combines two simultaneous energy modalities: high-intensity focused electromagnetic stimulation (HIFES) and synchronized radiofrequency (RF). The HIFES component stimulates the underlying facial musculature—primarily the masseter and frontalis—causing sustained muscle contraction and hypertrophy, while the RF heats the dermis and superficial subcutaneous tissue to trigger collagen remodeling and skin tightening. The two energies are delivered in real-time synchronization through a handheld applicator, with treatment cycles typically lasting 20 minutes per session.
