What Is A Long Pulse Laser Hair Removal Machine?

Long pulse laser machine use 1064nm wavelength for hair removal. 1064nm is the safest wavelength for hair removal especially for dark and black skin. Due to the 1064nm wavelength could penetrate deeper to the skin than other wavelength, it will not burn the surface of the skin ever for black peron. Long pulse Nd: YAG laser machine equips delicate fiber handpiece, which can emit 1064nm long pulse wavelength laser precisely. This 1064nm wavelength laser reach skin tissues depth of dermal layer, selectively works on target area such as melanin of hair follicle, epidermal and dermal pigmentation into the skin, surface and deep skin infections, acne scars, vascular lesions, etc. Due to its adjustable big spot, it brings high work efficiency for hair removal and skin issues. Currently it’s widely used in clinical medical and beauty fields.

How Does Long Pulse ND Laser Hair Removal Machine Works?

1064nm long pulse ND YAG laser is selectively absorbed by the deeper levels of the dermis and allows for the treatment of deeper vascular lesions like telangiectasias, hemangiomas and leg veins.

The 1064nm laser energy is delivered using long pulses which are converted into heat within the tissue. The warmth impacts the vasculature of the lesions. Additionally, the ND: YAG laser can treat at a more superficial level, by heating the subcutaneous skin (in a non-ablative manner), so it stimulates neo collagenases which improves the looks of facial wrinkles.

The ND: YAG Laser operates at a way higher wavelength than other lasers used for hair removal which suggests that it’s been CE approved to be used on individuals with tanned and ethnic skin. Therefore, long pulse ND: YAG Laser is the best laser hair removal machine for dark skin.

Working Principle

1. Selective absorption–Long pulse 1064nm laser irradiated onto the skin, pigment particles in the skin (such as melanin in various pigmentation spots such as freckles, sunspots, melasma, etc.) selectively absorb the energy of the laser. With this character, long pulse laser break pigment particles into smaller pieces. With human body immune system and metabolism, they are drained out. Simultaneously hemoglobin in dilated capillaries also has a high absorption rate for specific wavelengths of the laser.
2. Photothermal effect–10600nm laser causes the temperature of the target tissue to rapidly increase. Then high temperature will decompose and break down pigment into smaller particles, which are then gradually metabolized and excreted by the body’s immune system, thereby achieving the effect of removing spots. For abnormally dilated capillaries, high temperatures can cause hemoglobin to coagulate, seal blood vessels, and improve the problem of red blood streaks.
3. Optomechanical effect–Under high-energy laser irradiation, the target tissue may generate small explosive forces, further damaging pigment particles or abnormal vascular structures.
