Selective Photothermolysis is based on the absorption of light by target chromophores, it is necessary to choose the most appropriate chromophore for the application being used and the desired outcome and then to apply the optimal wavelength spectrum and pulse duration for that chromophore.

By emitting light in the 400-1200nm spectrum, LHE directly targets hemoglobin in vascular lesions. Low fluences are maintained without compromising results as heat energy further elevates the chromophores core temperature to the coagulation point. Once coagulated, the body's natural healing process works to remove the lesion, which then scabs and drops off or is absorbed by the skin.

• LHE targets directly targets hemoglobin found in vascular lesions.
• The treated cells are naturally eliminated by the body and replaced with new cells.
