How does SLT work?

SLT uses three-nanosecond high-energy beam of light to induce the same cell replacement mechanism as ALT, but without the burn. SLT does this by delivering just enough energy to the TM to target specific melanin-rich cells for replacement, without disruption to the surrounding tissue and structure of the TM. The SLT laer pulse is much shorter than the thermal relaxation time of the target chromophore (melanin) in the pigmented TM and so damage toneighbouring cells is avoided. SLT is more precise than ALT because one ALT laser shot carries 6,000 times the energy of one SLT "drop of light", which accomplishes the same effect on the TM.
