Add Electrolysis Hair Removal To Your Spa Menu
Electric hair removal has been around for over 150 years. It is a proven and scientifically recognized method worldwide, demonstrated to be effective in all treatments targeting hair follicles.
It is the only method that offers 100% permanent hair removal by completely destroying hair follicles and ensuring no regrowth.
In addition, the electric hair removal technique is the complementary and essential solution to photoepilation treatments.
EVOLUTION ST350 operates at a single frequency of 6.78 MHz, which is both efficient and regulated by the US FCC (Radio Frequency Family), and is recognized by electrologists worldwide.
VECTOR MODULATIONS
Unlike conventional devices that transmit a constant and uncomfortable electric current, Evolution ST350 enhances results, concentrates energy, and reduces discomfort thanks to Silhouet-Tone’s exclusive Vector Modulations technology.
This technology modulates the duration, shape, and intensity of the current in ultra-fast decreasing sequences. During treatment, it reduces the discomfort associated with electrolysis while preserving the skin’s surface.
