I don’t understand. Fever Master's 45-degree constant temperature fever therapy uses "deep source heat" technology to allow thermal energy to fully penetrate the human body system, simultaneously eliminate subcutaneous fat and visceral fat, enhance immunity, improve constipation and uterine cold, and repair damage at the same time It is a health management system that can activate diseased cells, activate dormant cells and promote cell regeneration, improve pain, and then activate cells, promote metabolism, prevent diseases, reduce fine lines, firm and rejuvenate skin, and shape contours. If customers don’t do it, it’s because they don’t understand the efficacy of Fever Master and are afraid.
