The Deep IR system is run off a halogen lamp filtered at 850-1,350 nm. This creates a wavelength spectrum that will penetrate to a proper depth and then be absorbed by the water content and converted to heat. The system combines long pulse durations (seconds) and fractional delivery to achieve this penetration.
In order to allow high amounts of deeply penetrating wavelengths of light to target water in the mid-deep dermis, extensive cooling is required to protect the upper portion of the skin. The Deep IR runs on the Starlux 500 platform that utilizes advanced two-staged cooling. In addition to cooling, another important safety feature unique to this light-based technology is a series of electronic field sensors (E-Field Sensor) which indicates a proper contact to the skin. Once proper contact is established, the system begins a precooling stage (0-5 seconds), a firing stage (5-10 seconds), followed by a one second post-cooling phase. If at any time, the contact to the skin is lost, the firing phase is stopped, but the cooling is continued. The patient feels a slight warmth toward the end of the firing phase of the treatment.
