When it comes to laser hair removal, it's important to consider what type of laser machine is best for you. There are several different types of lasers that are used for this purpose, and not all machines are suitable for all skin types. Let's take a closer look at the different types of lasers available and how they can be used to achieve the best results. The Ruby laser is not recommended for patients with darker skin tones, such as those with tanned skin, as it produces a reddish light that can be absorbed by the melanin in the hair.
The diode laser is another device used in some medical spas for lighter skin tones. It has a wavelength of 810 nm, which has a slightly deeper dispersion in the hair follicle than a similar alexandrite laser. However, it doesn't have a cooling burst and instead relies on the use of a cooling gel after treatment. Studies have shown that those who receive diode laser treatments have a higher incidence of pain during treatments.
The alexandrite laser has a wavelength of 755 nm, which slightly reduces the concentration of melanin in hair follicles in light or olive skin tones. It also uses a cooling spray for a more comfortable experience. Laser hair removal is most effective for people with fair skin and dark hair, but it can be used successfully on all skin types. With its large spot size (up to 18 mm) and its high repetition rate, it is the fastest hair removal laser in terms of pulse speed.
No matter what laser or light-based device is used, the concept of how laser hair removal works is the same: selective photothermolysis. Be wary of spas, beauty salons, or other centers that allow laser hair removal to non-medical personnel. After finding the laser hair removal center that best suits your needs, your laser technician must consider several factors to choose the configuration that best suits your needs.
