There are several types of laser for hair removal, each with a different technology. They will provide different results for different skin and coat types. Therefore, before closing a laser hair removal service like 3D Lipo London Laser hair removal , it is important to assess which technology is used to understand whether it will be the most efficient for your case. With that in mind, we have listed in this article 3 of the laser technologies most used in the hair removal market today. Learn more about them and stay on top of the subject.
Understand how laser hair removal works
The laser has become popular in recent years for providing long-lasting hair removal. That is, at the end of the treatment, the client will not have to worry about depilation for a while. The technology makes use of beams of light that focus on the hair root, cauterizing and destroying the thread. With the frequency of treatment (which usually revolves around 5 to 10 sessions), damage to the hair follicle will occur, preventing/delaying the growth of new hair.
How to choose the best laser for hair removal?
To achieve the desired results it is important to choose the right technology for your skin and coat type. For example, there are devices that work by attracting melanin in the hair, which makes them ineffective for black skin. But it is already possible to find technologies that act by attraction to hemoglobin, which makes hair removal possible in black skin. Therefore, the most important thing is to know how to identify how the technology works.
Next, we will present the most common types of laser for hair removal and point out who they are indicated for.
3 types of laser for hair removal
The main difference between the types of laser for hair removal is the size of the waves fired. This directly affects the efficiency of hair removal for each skin type. For example, devices with longer waves are the most recommended for black skin, as they allow less absorption of light by the epidermis. That is, the risk of burning the skin due to low contrast is reduced.
See below which are the most common technologies in the hair removal market.
Among the three types of laser hair removal, Alexandrite has the shortest wavelength, with 755 nm (nanometers). Due to this characteristic, the technology is indicated for people with light skin and light hair, being able to meet between phototypes I and IV. This happens because the equipment’s laser beam searches for melanin to perform the shots, thus, it is able to provide deep penetration to the middle dermis. The vast majority of Alexandrite equipment has cooling at the tip of the device to freeze the area to be depilated, providing a more comfortable treatment.
Diode laser technology is intermediate between the most common types on the market, with a wave of 810 nm (nanometers). It serves mainly people with light skin and dark hair. Because it has a longer wave than Alexandrite, it is able to penetrate deeper into the hair follicle, therefore, it is also effective in black skin. Its technology counts on a beam of pure, concentrated and intense light, providing highly efficient results. Like Alexandrite, the Diode laser also has cooling technology that provides a less painful hair removal session.
It is the type of hair removal laser with the largest wave size, at 1064 nm (nanometers). Therefore, the technology is the most efficient for treating dark skin with dark hair and black skin. This happens because the fired beam has low affinity with melanin and has a high penetration capacity. ND-YAG can be used in various regions of the body and face, being able to reach even the deepest targets or tissue below the skin (fat). In this case, the intensity of the ray must be adjusted according to the treated region.
So…which one will you choose?
