China Suppliers Factory Long Pulse Nd:YAG Laser Machine for Hair Removal, Tattoo Removal & Skin Rejuvenation
1. Laser Emission
The Nd:YAG laser emits long pulse light at a wavelength of 1064 nm, penetrating deeply into the skin.
2. Selective Photothermolysis
The laser energy is absorbed by the pigment in the target tissue (such as hair, blood vessels, or pigmentation), converting the light into heat.
3. Thermal Effect
The heat generated destroys hair follicles, blood vessels, or pigment cells, providing effective hair removal, vascular treatment, or pigmentation reduction.
4. Deep Penetration
The long pulse duration allows the laser to penetrate deeper tissues without damaging surrounding healthy tissue.
Frequently Asked Questions
Q: How does the 1064 nm wavelength benefit skin treatments?
The 1064 nm wavelength of the Nd:YAG laser allows for deep penetration into the skin dermis, bypassing superficial melanin. This makes it highly effective for targeting deep-seated hair follicles and vascular structures while minimizing the risk of epidermal damage, especially in darker skin types.
Q: What is selective photothermolysis?
Selective photothermolysis is a precise treatment principle where specific laser wavelengths are absorbed selectively by target chromophores (pigment, blood, or water) without affecting the surrounding healthy tissue. The light energy converts to heat, safely destroying the target.
Q: Can Nd:YAG lasers be used for vascular treatments?
Yes. Due to the thermal effect, the laser energy is absorbed by hemoglobin in the blood vessels. This heat causes the vessel walls to collapse and seal, making it an excellent option for treating spider veins, vascular lesions, and redness.
Q: Why is the long pulse duration important?
A long pulse duration delivers energy over a longer period, allowing the heat to safely build up in larger target structures like hair follicles and veins while giving the surrounding skin time to cool down, reducing the risk of burns.
Q: Is Nd:YAG laser treatment safe for dark skin?
Yes, the 1064 nm Nd:YAG laser is widely considered the safest laser technology for darker skin tones (Fitzpatrick scale IV-VI) because its wavelength is less absorbed by melanin in the epidermis compared to shorter wavelengths.
