The Alexandrite laser is considered the world reference in laser hair removal<\/strong> for fair skin. With its 755 nm wavelength, perfectly absorbed by melanin, it delivers fast, long-lasting results. But is it right for your skin? How does it compare with other technologies? CtrlZ tells you all about this must-have laser. <\/p>\n The Alexandrite laser is a class IV laser<\/strong> used in aesthetic medicine, mainly for permanent hair removal. Its name comes from the alexandrite crystal that forms its active medium. <\/p>\n This laser emits a light beam at a wavelength of 755 nm<\/strong>, in the visible light spectrum (violet\/pink beam). This wavelength has a particularly high melanin absorption coefficient, making it the most effective laser for targeting the pigment in hair. <\/p>\n The principle is that of selective photothermolysis<\/strong>:<\/p>\n The 755 nm wavelength corresponds to the absorption peak of melanin. This is what makes the Alexandrite laser so effective: it precisely targets the hair pigment while preserving surrounding tissue. No other laser can match this selectivity on fair skin. <\/p>\n<\/p><\/div>\n The Alexandrite laser is particularly recommended for :<\/p>\n Tanned skin absorbs some of the laser energy instead of the hair. The risk of burns<\/a> is therefore significant. Before resuming sessions, you need to wait until your skin is completely untanned (at least 4 weeks without exposure). At CtrlZ, tanning tests are systematically carried out. <\/p>\n<\/p><\/div>\n How does the Alexandrite laser compare with other hair removal technologies?
