How does laser hair removal work?<\/p>\n

Laser hair removal is based on the principle of selective photothermolysis. It will use special wave laser energy like 808nm Diode Laser<\/a>, mainly target the melanin at the follicle. After the melanin absorb the laser energy, which weakens the hair follicle’s ability to grow, thus reduce the hair growth.<\/p>\n

But please don’t worry, the laser will mainly target the melanin at the follicle. It usually won’t significantly affect the surrounding skin or sweat glands.<\/p>\n

The difference between hair follicles and sweat glands<\/p>\n

Hair follicles and sweat glands are totally located in different layers of the skin and have different functions. Let’s use a simple picture to explain it.<\/p>\n

Hair follicles at the dermis.<\/p>\n

Sweat glands at the deeper in the dermis, close to the subcutaneous tissue.<\/p>\n

Hair follicles mainly focus on hair growth.<\/p>\n

Sweat glands mainly focus on producing sweat and regulating body temperature.<\/p>\n

\"Can<\/p>\n

So during the laser hair removal treatment, the laser energy will preferentially target the melanin at the hair follicle. Because follicles contain plenty of melanin, so it’s easier to absorb the energy and generates a thermal effect.<\/p>\n

However there are very little melanin at the sweat glands, so the sweat glands won’t be the primary target of the laser. Although the laser energy will pass through the surrounding skin tissue, sweat glands will not absorb too much energy. Thus under the normal treatment parameters, it won’t get damaged.<\/p>\n

That’s why the laser hair removal technology can mainly target the hair follicle, while minimizing the impact on surrounding skin tissue.<\/p>\n

Actually, most concern about “laser hair removal affects sweating” are misunderstandings about the principles of laser treatment and an exaggeration of temporary post-treatment reactions.<\/p>\n

With the development of laser technology, laser treatments have become increasingly precise, and are now widely used in long-term hair removal treatments. Such as Diode Laser Hair Removal<\/a> treatment, super cooling performance will be more safe and comfort experience. If you are going to buy a new machine, FDA cleared diode laser machine will be your first choice.<\/p>\n

Once people really learn about how the laser works, they will keep a more rational mindset to these concerns.<\/p>\n
