1. What is laser hair removal?Laser hair removal uses a laser equipment that emits laser light of a specific wavelength, which selectively act on the root of hair follicles. When energy is absorbed, the hair follicles root are damaged and fall off completely, so hair removal is achieved.
2. Will hairs be completely removed with one single laser hair removal treatment?
One single treatment of laser hair remover will not remove all the hairs, because hair has three growth phases, the active phase, transitional phase, and resting phase. When laser hair removal treatment is applied, it only acts on the hair follicle cells thatare on the root of hairs in the active phase, depriving their ability of growth permanently. As for the hairs in their
transitional or resting phase, the laser cannot reach their follicle cells directly, so only hairs can be temporarily removed.

No, depending on the area of hair remover and condition, different number of treatments will be applied, also laser of different energy levels will be used. This is because hairs in different areas have different thicknesses, density, and ability of regrowth. In general, the denser the hairs, the thicker the hairs shaft, the higher energy level of the laser light is required, and the more treatments are needed.
7. What is the laser hair removal process like?
Prior to laser hair removal, the thickness of hair follicles and the density of hair should be measured with instruments, based on which a hair removal plan can be made.

8. Is laser hair removal painful?
It is certainly a lie to claim that laser hair removal is not painful. After all, it works on the very deep hair follicles root.

Usually pain is not clearly felt when hair on limbs is being removed. A slight tingling pain may be felt when armpit hair or facial hair is being removed.
9. Will laser hair removal damage the skin?
Some must say, “When the hairs are removed with laser, it will surely burn the skin, because such a heavy amount of laser light is shot at skin”.

It will not burn the skin, as long as it is operated correctly.

removal, etc. Such hairs will not grow after the first laser hair removal treatment, rather, the hairs that were in their transitional or resting phase will grow into thin and soft hairs.
12. Will laser diode hair removal accelerate hair growth?
It will not. Although hairs seem grow faster after laser hair removal, it is only a misconception. Besides, if the hairs are
uprooted, after a period of time, the regrown hairs will only be thinner and softer, and less able to grow faster.
13. Is laser hair removal effect permanent?
Laser hair removal is a complete destruction of hair follicles cells in the active phase. Generally, multiple treatments can
completely destroy hair follicles cells. Once the hairs in active phase are completely removed, it will not grow again. This
effect is permanent (only if multiple treatments are received).

15. Is sunbathing allowed immediately after a laser hair removal treatment
The skin surface is damaged to a certain extent after a laser hair removal, and the self-repair mechanism is randomly activated, which means that the selfprotection function of the skin declines and it is sensitive. At this time, further irritation of the skin should be avoided, hence immediate sun bathing is inadvisable.
16. What if I find red spots or swelling after a laser hair removal treatment?
Laser hair removal causes a slight tingling pain, and after the treatment, there may be mild burning sensation, mild papule caused by swelling hair follicles, or erythema on the local skin. Cold compression can be applied. If the erythema persists, it is recommended to use skin gel containing recombinant human epidermal growth factor externally to enhance healing; edema is accompanied by pain, and it is recommended to externally use mild steroids such as fluticasone propionate.
17. How long is required to completely remove hair with laser?
