Which diode laser is best for hair removal?

 

There are various hair removal methods on the market, among which hot wax hair removal and laser hair removal are the two most common ones. Today we will talk about one of the best laser hair removal methods, which is 808nm diode laser hair removal.

 

What is 808nm diode laser hair removal？

The principle of the 808 diode hair removal instrument is to use the photothermal principle of laser and the selective black absorption principle to selectively destroy melanin in hair follicles to achieve hair removal. At present, in clinical practice, the treatment effect is relatively rational, and multiple treatments can achieve the goal of permanent hair removal.

The wavelength of the 808 diode hair removal instrument is 808 nanometers. 808 is a single wavelength with high energy, which can accurately select melanin in hair follicles. The laser can penetrate the skin and reach the hair follicle area. The melanin in the hair follicles absorbs the laser energy, causing a sharp increase in hair follicle temperature, leading to nipple atrophy and inability to provide nutrition for hair, thus achieving the goal of hair removal. At present, the therapeutic effect is relatively ideal in clinical practice, and repeated 3 to 4 times can achieve permanent hair removal.

 

How to distinguish 808 diode laser hair removal？

In terms of basic configuration, we distinguish 808 diode laser hair removal mainly through power and wavelength.

Power

The power of the 808 usually refers to the host power, which includes 300w, 600w, 1000w, and 1200w. However, half of the handle power is determined by the number of target bars, with each target bar being 50w. Typically, the machine is configured with 10 and 12, which are 500w and 600w. From the perspective of hair removal effect, the power difference is not significantly reflected. However, high-power optoelectronic devices are more likely to achieve clinical endpoints, with shorter operating times and shorter pulse widths, resulting in less skin damage and higher comfort.

Wavelength

Three different laser targets (755+808+1064nm), with different wavelengths of J-machine light beams acting on hair follicles at different depths, provide a wider range of hair removal. The 808nm laser light system uses standard laser light with a wavelength of 808nm. Semiconductor laser light emits near-infrared light waves, which can penetrate deep into the roots of hair follicles, heat the pigments inside, and diffuse throughout the entire hair follicle. It can accurately damage hair follicles without damaging adjacent tissues, thus achieving hair loss. Suitable for all parts of the body and all skin tones. The 755nm wavelength band has stronger selective absorption characteristics, suitable for hair removal in a wider range of hair and skin tones, especially for easy removal of light and fine hair. 1064nm laser is based on selective photothermal decomposition. Due to the abundant melanin in hair follicles and hair trunks, melanin is distributed between cells in the hair ball matrix and transferred to the structure of hair trunks. 1064nm is suitable for people with brown skin or darker skin.

So high-power lasers are more efficient, and for different skin tones, it is necessary to choose a three band laser to penetrate different levels.

Effectively remove hair

808 diode freezing point painless hair removal generally requires three to five times to completely remove hair, for two reasons:

1. Hair follicles are mostly bundled together in groups of three, opening at the same pore. One hair in the pore is the hair growing from one of the three follicles below it, so a single treatment can only destroy one hair follicle in a group.

2. The rest period is almost ineffective.

The growth process of hair is divided into growth period, regression period, and resting period. Only hair nipples in the growing stage contain melanin, while hair in the degenerative and dormant stages, due to the degeneration of the nipples, is 75% effective for painless hair removal at freezing point 808 in the growing stage and 25% effective in the degenerative stage. Therefore, no light/laser can remove hair from these two stages. This is why black and coarse hair is easier to remove than light and fine hair, and it is also why hair removal requires multiple treatments. Effective hair removal is not about not growing hair at all, but about the hair removal area where the hair grows thinner and sparser, the color becomes lighter, and small hairs grow without affecting sweating function.

 

Inspection work before photoelectric hair removal operation

1. Inquire if the customer has a photo allergy, as some people may experience redness, swelling, and itching when exposed to the sun. This phenomenon cannot be treated with photoelectric projects;

2. Those who have completed optoelectronic projects in the same area within one month can only do so after one month;

3. Avoid reflective mirrors and eyes when treating light; Jewelry, watches, and other accessories should not be worn during the treatment process;

Pregnant women, patients with severe hypertension, and those with open wounds are prohibited from doing it.

 

Precautions after laser hair removal

1. After treatment, there may be slight redness and swelling, sensitive skin, and a feeling of heat or itching. If pain is felt, apply ice to alleviate it.

2. Pay attention to sun protection.

3. No hot water scalding and vigorous scrubbing.

4. Avoid using it together with other hair removal products.

 

5 Reasons for Hair Removal

1. Smooth skin is loved by everyone

2. In the season of exposing arms and legs, I can't cover my fur

3. Raise your hand and look back, no longer embarrassed

4. Brighten skin tone and increase confidence points

5. Let your makeup no longer be affected by fluff and powder

 

When is the best time to remove hair?

The temperature for spring hair removal is comfortable and not easy to sweat, which will not affect the normal repair of the hair removal position. The ultraviolet radiation is weak, and the protection after hair removal is simpler. In summer, the skin will darken to some extent due to strong ultraviolet radiation. When the skin has more melanin, it increases the target area of the laser, which is equivalent to a portion of the energy being intercepted by the skin. In contrast, after covering the skin for a winter in spring, there is a greater difference in skin tone and hair, resulting in better results.

In summer, the temperature is high and the skin is prone to sweating and oil production. Laser hair removal also requires skin care and machine use. For example, it is important to pay attention to sun protection or the temperature of the environment in which the instrument is used, and so on. Hair removal in autumn is not that troublesome, with relatively weak ultraviolet rays and clothing covering it. There is no need to deliberately consider sun protection, and the skin is stable in autumn with fewer adverse reactions, making it easy to achieve the best hair removal effect.

The benefits of winter hair removal

The hair removal cycle spans 3-6 months, with winter hair removal and early summer wearing short skirts. In winter, optical hair removal is easier to absorb light energy, resulting in better results, better protection from sunlight, and no pigment deposition. The winter weather is cool, non sweating, less greasy, convenient for care, and faster for recovery.

Will summer hair removal affect sweating? The answer is that it will not affect sweating. Hair grows in hair follicles, and sweat is produced through sweat glands and seeps out of the skin surface, not directly related to hair follicles. In the skin structure, hair follicles and sweat glands are two independent tissues, so there is no need to worry about hair removal affecting sweating.
