“The Nd:YAG laser has the longest wavelength of these 4 lasers and therefore penetrates the deepest into the skin. It is, therefore, theoretically the least likely of the 4 lasers to produce side effects in the superficial skin pigment. However, the original combination of Tar and this laser as utilized with the SoftLight™ process - was shown to produce complete hair regrowth 6 months after treatment. Long-term effectiveness of hair removal has been the problem in using the Nd:YAG, with, and subsequently without, a tar solution. There is not enough data to show that this laser can produce longer-term hair removal.”
Is this true???
