Flash thermolysis uses High Frequency only. It coagulates/cauterises the tissue delivering the current within 100 th – 1000 th of a second by way of a pulse. This method of treatment is only available on a computerised machines such as the Instantron Elite Spectrum and the Apilus machines.
The pulse is an intense shot of energy at the tip of the needle and instead of a pear-shaped pattern that forms around the tip as in low slow thermolysis or the Blend – in Flash it is like a ball. Insulated needles or probes are more often than not used ensuring the current stays at the tip enabling the operator to pulse the current one or more times along the length of the follicle from the base to the bulge to denature cells and successfully release the hair.
