How does laser hair removal work?
Before discussing Diode and YAG, let’s first define laser hair removal. The removal of hair with a laser is a popular procedure, but how exactly? In essence, a laser’s light is absorbed by hair—more precisely, melanin. The heat that results from this light energy’s conversion harms the hair follicles (responsible for producing hair). The laser’s damage slows or prevents the development of new hair.
The hair follicle must be joined to the bulb for laser hair removal to be successful (the one underneath the skin). Additionally, not all hair follicles are growing hair at that period. This is one of the key reasons why laser hair removal typically requires a few sessions to be effective.
Laser Diode Hair Removal
Diode laser devices employ light with a single wavelength. The melanin in the hair is readily abrupted by this light, which subsequently obliterates the follicle’s root. Although it has a modest fluence, diode laser hair removal employs a high frequency. This indicates that it can efficiently remove hair follicles from a spot or small region of skin.
Sessions with the diode laser may take longer, particularly on larger regions like the back or legs. As a result, some patients may experience skin irritation or redness following a diode laser hair removal treatment.
Laser Hair Removal using YAG
Laser hair removal is problematic since it destroys skin melanin, which is also present. As a result, those with darker complexion may find laser hair removal to be fairly risky (more melanin). Due to the fact that YAG Laser Hair Removal doesn’t specifically target melanin, it can treat this issue. Instead, the laser beam warms the hair follicles through selective photothermolysis when it reaches the skin tissue.
The longer wavelengths of the Nd: Yag technology make it perfect for removing excessive hair from broader parts of the body. Although it is one of the most pleasant laser systems, the removal of finer hair follicles is not as successful.
Diode and YAG Laser Hair Removal Comparison
YAG laser hair removal penetrates the hair via the skin cells, whereas diode laser hair removal kills hair follicles by focusing on melanin. Because of this, diode laser technology works better on coarse hair and heals faster. However, YAG laser technology offers more pleasant sessions, shorter treatment times, and is perfect for removing big regions of unwanted hair.
While patients with darker complexion may choose YAG laser hair removal, individuals with lighter skin can often find diode laser hair removal to be beneficial.
Although new devices have been released to lessen discomfort, diode laser hair removal was once thought to be more unpleasant than other procedures. On the other hand, fine hair removal is difficult with older Nd: YAG devices.
