The MLAY radiofrequency device uses radiofrequency heating technology to raise the temperature of the dermis to 55–65°C, promoting collagen production and achieving firming, lifting, and wrinkle-reducing effects. While not specifically designed to "burn fat," some users have seen a reduction in facial fat (e.g., around the chin and jawline) and a sharper contour. Some even report a degree of "permanent" fat reduction. However, caution is advised to avoid excessive fat loss due to frequent or intense use.
