What light is used in laser hair removal?

The lasers used to treat unwanted hair growth can be grouped into two categories, according to their wavelengths; either the red light systems, the 694 nm ruby lasers or the infrared (IR) light lasers. The IR lasers include the 755 nm alexandrite laser, the 800 nm semiconductor diode laser and the 1064 nm Nd:YAG.

How many joules does it take to remove hair with laser?

Answer: 10-15 joules (1-5 level) IPL energy for home useful, the higher the energy level, the better the hair removal effect.

Which wavelength is best for laser hair removal?

Choice of wavelength

The absorption properties of the main chromophore of hair follicles – melanin, and surrounding epidermis have suggested that lasers emitting light in red and near infrared spectrum are the best light sources for the hair removal [3,4].

What is happening in hair removal with light laser devices?

During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or delays future hair growth.

Does light work for hair removal?

If you have dark skin or light hair, you shouldn’t even attempt laser hair removal. At best, it won’t work, and, at worst, you can incur serious injury, because dark pigment will absorb the laser, potentially resulting in a burn.

Is it OK to pull hair out after laser?

You should not pull out loose hairs after laser hair removal. Laser hair removal targets the hair follicle to permanently remove hair from the body. For successful results the follicle has to be present so the laser can target it. Waxing, plucking or threading removes the root of the hair follicle.

Which is better diode laser or IPL?

The diode laser is most effective for darker terminal hair and is less effective on lighter, finer hair. … Intense pulsed light (IPL) devices are not lasers, but are “laser equivalents” in the sense that they use the same concept of selective photothermolysis to accomplish hair removal.

What is ND YAG wavelength?

Neodymium:Yttrium-Aluminum-Garnet Lasers

The Nd:YAG lasers operate at a wavelength of 1064 nm. These lasers are fiberoptic-delivered contact lasers that generate a free-running pulsed beam of energy.

What is ND YAG laser hair removal?

Nd Yag laser is the newest technique of laser hair removal. Its biggest advantages are that it usually works well and more effective on all skin types, including tanned skin (type I to VI). … The Nd Yag laser penetrates deeper into the layers of skin to get to the hair follicle which IPL systems can not do.

Which laser is best for thin hair?

The treatment of different colours of hair. Effective treatment of light coloured fine hair requires a laser with a high attraction to melanin such as the Alexandrite 755nm laser. Darker thicker hairs will respond better to the diode 810nm laser or Nd Yag 1064nm laser.

Is laser hair removal UV light?

As powerful as ionizing radiation is, the Food and Drug Administration (FDA) states the laser energy in hair removal procedures use non-ionizing radiation. “The light energy from these lasers actually remains superficially, it remains at the level of the skin,” Dr.

Do you regret laser hair removal?

But, as with any treatment that ends with more or less permanent results, not everyone is pleased with their decision. While some feel freedom after banishing all the hair on their bodies for good, others express deep regret — especially given how the conversation around body hair has shifted in recent years.

What happens if you don’t shave before laser hair removal?

As we mentioned a little earlier, if you don’t shave before your appointment, the laser will singe the hair resulting in a burn to your skin. In addition, if the hair hasn’t been shaved properly, treatment will not be as effective, and it may result in small temporary grazes on the top layer of your skin.

Is intense pulsed light safe?

Compared to laser treatment, intense pulse light treatment is safe to use. Unlike the laser treatment that focuses on just one wavelength of light at the skin, IPL treatment releases different light wavelengths. This makes penetrable deep into the skin without causing any harm.

What is the difference between IPL and laser?

The key difference between laser and IPL is the type of light. IPL (Intense Pulsed Light) is a broadband pulsed light source, whereas laser is a monochromatic coherent light source. Both methods target the melanin in the hair follicle and permanent results can be expected from both.
