Diode machines are relatively new to the laser hair removal market. Their energy source consists of semiconductors, known as diodes, grouped together to create a laser beam with a wavelength of 800-810nm. This is a longer wavelength, better for penetrating deep into the hair follicle. Diode lasers are generally safe on darker skin types and are ideal for removing thick or coarse hair. This makes the Diode hair removal laser system popular among men seeking treatment to remove back hair or chest hair.Alexandrite hair removal lasers
The Alexandrite laser is the most popular system for laser hair removal. It is also the fastest laser system available. For example, the Alexandrite laser can cover a large treatment area, such as the back in as little as 30 minutes. The downside of the fast laser repetition is pain. The Alexandrite laser is one of the least comfortable laser hair removal systems. Although newer machines have built in cooling devices to improve patient experience. The Alexandrite laser operates at a shorter wavelength of 755nm, making it ideal for targeting melanin in the hair follicles of individuals with light to olive skin tones.
Nd:YAG systems provide the latest advancements in cosmetic laser technology. Nd:YAG systems operate at a wavelength of 1064nm. Most other laser systems target the melanin found in hair and skin.laser hair removal using the Nd:YAG laser is safe for all skin types, even tan skin tones.
IPL laser hair removal does not utilize a true laser, but the equivalent in the form of Intense Pulsed Light (IPL.) Like lasers, IPL’s initiate photothermolysis by pulsing thermal energy that is absorbed by melanin in the hair follicle. The advantage of intense pulsed light is a customizable wavelength, energy level, and pulse duration .for multifunciton purpose .
Therefore ,There not have the best for hair removal but always have the most suitable products according to different customers need.
