The same principles utilized in fractional skin resurfacing at roughly a millimeter of depth are applied to the condition of lax and loose skin at 2-4 mm of depth. Using wavelengths in the 850-1,350 nm, the Palomar Lux Deep IR hand piece uses a halogen lamp to create a pulse duration ranging from 5-10 seconds, depending on desired depth. While
there are several skin tightening systems in the market (Cutera Titan, Alma Accent, Ther – mage), Deep IR is the only one to combine IR wavelengths with a fractional delivery system, making it possible to penetrate deeper with more energy as well as less discomfort and side effects. This technology is aimed at the thermal treatment of deep dermis to help tighten loose skin in the jowling areas, abdomen, arms, legs, and so on.
