What is the Best Laser Hair Removal Wavelength?

Laser hair removal is on the rise. The procedure is safe and effective, and works on almost anywhere on the body. There are many brands and models of at-home laser hair removal devices. These laser handsets come with a variety of settings – flash mode, energy level, or cooling. Then, you might wonder: which spec is the most relevant? The single most important spec for a laser lies within its wavelength.

Laser hair removal wavelength

Laser hair removal is now the standard in permanent hair reduction. Lasers with a wavelength of about 700 nm can penetrate skin and reach hair follicle. Several lasers are therefore effective:

• ruby laser (694 nm)
• alexandrite laser (755 nm)
• Nd:YAG laser (1064 nm)
• intense pulsed light (590-1200 nm)

The thermal energy in lasers causes follicular injury and thus stops hair growth. The procedure creates a large temperature difference between the melanin and its surroundings. Because the rapid volume expansion produces micro shockwaves that damage hair follicles.

Studies on laser hair removal show that long-term results are viable with all the lasers above. Multiple laser sessions are necessary at 4-6 weekly breaks when the hair has regrown. The result is variable after a course of 6-8 sessions, but often ranges from 3-6 months. Although, permanent hair removal is rare.

But the good news is that complications from the procedure is uncommon. Moreover, a patch test can reduce the chances of side effect. But darker skin is more vulnerable to complications than lighter skin. The most common complication is redness on the treated area. The symptom generally disappears after a few hours. Rarely, patients reported crusting and skin discoloration. But these are temporary symptoms that went away after 6-9 months.

It is also worth pointing out that the Nd:YAG laser is more effective on patient with darker-toned skin. The absorption of laser by melanin is low at 1064 nm, and thus prevent skin burns. The weaker thermal energy is compensated by the deeper penetration at longer wavelength. Also, the prolonged pulsed duration extends the period of heating of the melanin.

Laser hair removal procedure

The procedure of remove unwanted hair uses pulsed laser light radiation. That is because melanin in the hair follicles absorb light at certain wavelengths. The pulsed laser destroys hair follicles without damaging surrounding skin structures. It also reduces the risks of discoloration and scarring.

But laser hair removal has one major drawback: it is less effective to treat fine, light hairs. That is because they cannot absorb light as effective as thick, dark hairs. To improve the result, patient may apply eflornithine cream on the treated area.

There are two groups of laser that can remove unwanted hair: the red and infrared lasers. The red group includes the 694 nm ruby lasers. Whereas, the IR group include the 755 nm alexandrite laser, 800 nm diode laser and 1064 nm Nd:YAG laser.

The ruby lasers are effective on light-toned skin patients. The long-pulsed alexandrite lasers keep an edge on wavelength. Even though it has weaker melanin absorption, the laser reach deeper down the skin. Thus it reduces the risks of skin burn on darker-toned skin. At last, the 800 nm lasers provide optimal results on removing dark hair.

The Nd:YAG laser strikes the optimal melanin absorption among all skin tones. As a result, it is the laser of choice for hair removal. Its weak melanin absorption prevents damage to the surrounding skin structures. Meanwhile, its long wavelength allows it to penetrate the epidermal tissue. Moreover, its low scattering coefficient can focus heat on the deepest hair follicles. As a result, the Nd:YAG lasers are safe to use on darker skin types. But studies have showed its weaker efficacy than the ruby or alexandrite lasers.

Types of laser

Wavelengths that are smaller than the hair follicle tissue relaxation time are ideal. Because it keeps away from heat scattering from the hair. Handsets with scanners intended to further develop treatment speed. Moreover, security and solace for both the patient and the specialist. Also, smart filtering can restrict extreme covering and guarantee faster treatment speed.

Treating bigger regions can be tedious and difficult. But as of late a diode laser with a frequency of 800 nm has come available. This laser uses a vacuum framework that lifts up the treated region not long before the light. It brings about a less difficult treatment and killing the need for skin sedatives. Because of this skin extending, it is has lower impact levels, as the hair follicle is pulled nearer to the energy source.

Besides, the laser has a spot size of 22-35 mm which is identical to those of IPL sources. It speeds up the treatment system and put more light and more energy at the follicle. It can treat all skin regions with the huge spot and the vacuum strategy. Thus it is feasible to change to one more handset with a spot size of 9x9 mm to treat regions like the upper lip.

To reduce pain, the handset with a larger widow has a better cooling framework. When treating larger skin areas, the best option is a laser with higher pulse rates. Because it can speed up the treatment session. The IPL models for hair removal use frequencies between the 590-1200 nm.
