Abstract
Alexandrite laser is a pulsed laser system that emits light in bursts of low energy but with peak powers that are much greater than in continuous mode lasers. It can be either short-pulsed in the range of 50–100 ns (Quality-switched) or long-pulsed in the range of 2 to 40 ms. It has many clinical applications in medicine of which dermatology is one of those fields that alexandrite laser therapy made a difference in treating various skin conditions. It is effective in the clearance of pigmented lesions such as Nevus of Ota, nevomelanocytic nevi, lentigines and freckles; removal of tattoos of blue to black color; removal of unwanted hair in various skin types; and treatment of telangectasias. Reported complications are not specific to alexandrite laser and some are temporary, which can resolve with time.
