The SDL-15 is an impressive entry-level machine for the small salon. It produces twice the effective power required for laser hair removal procedures (including photo shaving on hair growth types 3-6: brown and black). The systems has a very efficient 1cm wide beam with a pulse duration of 0.09 seconds. Pulse frequency is user adjustable up to 7 emissions per second. The SDL-15 is not recommended for tattoo removal or general dermatology. A minimum of 120jcm2/second is needed for these advanced dermatology procedures. If you require a system which can perform these applications, please refer to the SDL-50 and SDL-80 units. Photo-shaving is also possible with blond and red hair types (2 and 3) using carbon dye. Each emission has an effective treatment size of 1 cm wide by 1 mm high and may feel like a brief pinch on sensitive areas. Very few clients describe the treatment as painful of uncomfortable. Should you encounter a client with a high degree of neural sensitivity the use of a topical numbing compound (included with kit) or ice pack is recommended. The SDL-15 Economy Salon Use Photo-epilator has a very sturdy and comfortable hand-piece. Active cooling is provided by way of a powerful 15cfm positive displacement micro fan. This keeps the diode cool during use which increases the performance and the life expectancy of the system.
