Here at Keiron Laser Institute we proudly use the ultimate DEKA laser device, Synchro Replay, which relies on three different sources: intense pulsed light, alexandrite for lighter Fitzpatrick skin phototypes (I – IV) and neodymium Yag for darker skins (V – VI).
As of today, the alexandrite laser is referred to as the gold standard in the field of epilation. The method as been approved by the American federal agency FDA and is considered to be a standard for treatments in international laser centers.
The use of alexandrite lasers is only allowed to medical personnel: it has a 755-nanometer wavelength specific for the menanin in hairs and hair follicles, which serves as a target to prevent surrounding tissues from being injured, also allowing a gradual epilation.
The laser only hits growing hairs (anagen) and for this reason more sessions are needed, one or more months away from one another, depending on the area which needs to be treated.
The advantages for the use of this laser are manifold: anesthesia is not needed, the execution is quick, the results are guaranteed.
The DEKA Synchro Replay laser also features intense pulsed light: in this case no laser ray is emitted but a beam of polychromatic light to which specific filters are applied that emit pulsations thanks to a lamp called "flash".
By absorbing this intense light, melanin (the pigment which colours the hairs) undergoes a significant increase in temperature. Heat is therefore passed on to the hair bulb which is led to necrosis. For this reason the technique is particularly effective with dark hairs.
The advantage of pulsed light is its painlessness and effectiveness: in fact, after being treated, hairs are rare and take long to grow again.
