it is a very effective way to eliminate unwanted skin cells or infections through heat. The process includes using a radiofrequency machine. lesions such as skin tags, milia, warts, acne, and sunspots can be eliminate with this treatment. A numbing cream is applied over the area of concern, then the RF needle that emits waves at an oscillating frequency for 5-10 seconds for each pulse – will deliver thermal energy into a localized region of tissue causing it to thermally coagulate without touching it directly. Over time – once the crust falls away from your treated spot – all signs of what you were concerned about will disappear for good leaving you looking youthful and radiant.
