What is YAG Laser? What is it like?
YAG Laser is short for Yttrium Aluminum Garnet laser. It is a solid state laser that uses yttrium aluminum garnet crystals as a medium to release energy. The released energy is converted to heat at various depths, which has the effect of destroying melanin pigments under the skin, causing dark spots, red spots, freckles, melasma, or tattoos to fade. It also has the ability to destroy hair roots. The heat from the laser causes the hair roots to gradually atrophy and eventually fall out.
The YAG Laser has two wavelengths:
- Wavelength 532nm for superficial skin, suitable for removing red spots, moles, freckles, sun spots, melasma.
- Wavelength 1,064 nanometers for shooting deep skin up to 7 millimeters, suitable for removing deep freckles, melasma, scars, tattoos and hair removal.
Using a YAG Laser to remove hair is more suitable for people with dark, black hair, such as Asians, than for people with light hair, such as Westerners, because the YAG Laser works by directly binding to melanin pigments.
However, each time YAG Laser hair removal is done, the hair will be reduced by about 15-20%. To see clear results or completely remove hair, it needs to be repeated several times every 4 weeks, at least 5-8 times.
How many types of laser hair removal machines are there in the world? What are they?
Laser machine type
IPL
IPL stands for Intense pulsed light. It is a high-intensity light wave that is not classified as a laser because it has a lower energy intensity and a wider spectrum than lasers. By emitting lower energy, IPL is gentler on the upper layers of the skin than lasers.
But at the same time, the light spreads in a wide area, which may cause the skin around the area to become more swollen and red, or burn the skin. If too much energy is used, the price of IPL hair removal is not as high as lasers, making it suitable for people with limited budgets, but it requires multiple treatments.
IPL is suitable for people with fair skin and thin hair.
Diode
Diode laser is a laser with a variety of energy wavelengths from 800-810, 940, 1,064-1,350 nanometers. Which has the advantage of being able to set the energy to suit the hair type, hair color, skin color, or area to be treated. Diode laser is an energy wave that absorbs a lot of melanin pigments, is highly effective in removing hair, and can reach deep into the skin. It also helps stimulate collagen, making the skin smooth and reducing dullness. However, the Diode Laser machine has a disadvantage: it is not suitable for treating small areas or areas that are sensitive. It is more suitable for removing hair from large areas, such as removing hair from arms or legs.
Alexandrite
Alexandrite laser is a laser that uses Alexandrite crystals as a medium to release energy. It has a wavelength of 755 nanometers, delivers energy deeper and captures skin pigment better than IPL machines, but delivers energy for a shorter period than YAG laser machines. It is suitable for people with fair to honey-colored skin, yellow skin, and is suitable for removing hair from large areas, such as legs, arms, etc.
Ruby
Ruby laser is a laser that uses ruby crystals as a medium to release energy. It is the world’s first hair removal laser technology. The wavelength is 694 nanometers, causing less irritation, but it cannot remove the hair roots. It is suitable for hair removal in cases where the hair is not thick, soft or thin.
Nd-YAG
Nd-YAG Laser is a type of YAG laser that contains https://ufabet999.app Neodymium ions. It may be called YAG Laser or Gentle Laser. It is the same type of YAG laser. Nd:YAG laser has a wavelength of 1,064 nanometers, can penetrate 5-7 millimeters deep into the skin layer. It is effective in removing hair down to the root. It is suitable for removing all skin colors and hair colors, except white or gray hair.
