RF skin tightening, also known as Radio Frequency, a popular treatment in our clinic no downtime required can be done during your lunch break .. An excellent non-surgical solution to turning back the clock on ageing, RF targets lax skin to improve the tightness and smoothness of loose skin on the face, neck and body. The handpiece transmits radio waves through the upper layers of the skin to the dermis, heating it to between 39-45°c while the epidermis remains undamaged and unaffected.
