Does laser depilation hurt? How many times does laser hair removal need to be done to completely get rid of it?

Laser hair removal technology uses the principle of selective pyrolysis of light, uses laser energy to destroy the rich melanin in hair and hair follicles, inhibit hair growth and fundamentally remove hair. Let’s talk about laser hair removal.

Laser hair removal

Hair and hair follicles are rich in melanin, which is much darker than the surrounding skin. When the laser with strong penetration ability enters the skin, the light is scattered in the skin and selectively absorbed by the melanin in the hair stem and hair follicle. These melanins absorb light energy and convert it into heat energy, which increases the temperature of hair follicle. When it reaches a certain degree, its structure is irreversibly damaged, and the hair follicle denatures, shrinks and no longer grows, so as to achieve a long-term hair removal effect.

Laser hair removal technology uses the melanoblasts in human hair follicles. When we irradiate the fixed wavelength laser deeply and sufficiently on the melanoblasts in the deep part of hair follicles, it will cause melanin burst. The result of melanin burst is likely to cause hair follicle damage and hair loss.

Will laser hair removal affect perspiration?

Of course not. The sweat of human body mainly depends on small sweat glands, while laser hair removal is to sweep hair follicles. Hair follicles and sweat glands are two independent tissues. Hair grows from hair follicles, while sweat glands are next to hair follicles. The two are not the same thing. Therefore, laser hair removal will not damage sweat glands and affect perspiration. According to the picture above, sweat glands and hair follicles are far apart.

Does laser depilation hurt?

It must be a lie to say there is no feeling at all. Xiaobian has experienced that facial depilation is more powerful than physical depilation, but generally speaking, it is within the acceptable range. The principle of laser hair removal is that the laser hits the hair, the hair absorbs light, generates heat and falls off, and there is still a sense of burning. But now laser therapy is generally equipped with cooling devices to protect the skin, so the pain will be greatly reduced.

How many times does laser hair removal need to be done to completely get rid of axillary hair?

The specific frequency is related to many factors such as individual skin and hair type. It usually takes 3-5 times, and some people even need more times. There are three stages in the human hair growth cycle: growth period, degenerative period and resting period. Only the hair in the growth period can be effectively removed. These three growth cycles exist at the same time, so to achieve more complete hair removal, we must go through multiple treatments.
