Hello, Maggie uses high radio frequency equipment to emit huge energy waves to remove wrinkles in the dermal layer. Prompts collagen to shrink immediately under the action of heat energy, and is continuously activated and renewed to reorganize collagen structure, thereby achieving the effect of wrinkle removal. The ultimate sonic facelift uses ultrasonic heat energy to be directly transmitted to the lower part of the subcutaneous fat layer, inducing deep collagen regeneration to achieve skin lifting and youthful effects. No matter which one you choose, Thermage or Extreme Sonic Facelift, you can achieve good wrinkle removal and skin tightening effects. However, extreme sonic facelift can affect the lower part of the subcutaneous fat layer. Therefore, Thermage is suitable for people with shallow wrinkles, and Extreme Sonic Facelift is suitable for people with deep wrinkles.
