808nm laser is a laser with a specific wavelength, which is widely used in modern medicine, beauty, scientific research and other fields, especially in hair removal and skin treatment. Its unique wavelength enables it to effectively penetrate the skin and achieve therapeutic effects.

In this article, we will explore the uses of 808nm laser in depth, especially in laser hair removal machines, and discuss its principles, advantages, scope of application and other related application areas.

What is the principle of 808nm laser?

808nm laser is a type of near-infrared laser with a wavelength of about 808 nanometers. Laser is a technology that excites particles and allows them to release energy. The wavelength of 808nm laser can effectively penetrate the surface of the skin and reach deep into the hair follicles. This wavelength has the best absorption effect on melanin in the skin, especially for thick and dark hair, and can give full play to its effect at a lower energy output.

The working principle of 808nm laser is based on the principle of selective photothermal effect. After passing through the surface of the skin, the laser is mainly absorbed by the melanin in the hair and converted into heat energy, which then heats and destroys the structure of the hair follicle. Since the hair follicle is the root of hair generation, once the hair follicle is destroyed, the hair cannot regenerate, thus achieving the effect of hair removal.

This wavelength of laser has a relatively mild effect on the skin, and the energy transmission is rapid and accurate, ensuring the efficiency and safety of the treatment process. Therefore, 808nm laser is widely used in various skin treatments, especially in laser hair removal machines.

What is the use of 808nm laser?

In the process of laser hair removal, 808nm laser hair removal device is regarded as one of the most commonly used and effective devices. Traditional hair removal methods such as shaving, plucking and waxing can only temporarily remove hair, and may cause skin irritation, hair inversion and other problems. The 808nm laser hair removal device is a highly targeted and long-lasting solution.

1. Hair removal effect

The 808nm laser hair removal device uses heat energy to act on the hair follicles, which can accurately destroy the melanin in the hair follicles. When the laser passes through the skin and reaches the deep part of the hair follicles, the hair follicles absorb the laser energy and produce a thermal effect, which damages the hair follicle tissue and inhibits the regeneration of hair. This process is usually completed after multiple treatment cycles, and because the hair follicles are damaged, the speed of hair regeneration will be significantly slowed down, and the effect of permanent hair removal will eventually be achieved.

Due to the efficient energy absorption characteristics of the 808nm laser hair removal device in selective photothermal action, this laser is particularly suitable for removing hair from multiple parts such as body hair, armpit hair, and facial hair. Compared with traditional hair removal methods, the 808nm laser can not only provide long-term hair removal effects, but also cause minimal damage to the skin during treatment.

2. Safety and comfort

Compared with other types of lasers, the 808nm laser hair removal device has better safety and comfort. First, because the 808nm wavelength can penetrate deeper into the skin and reduce thermal damage to the epidermis, there is usually no obvious skin burns or redness after treatment. Secondly, modern laser hair removal machines are usually equipped with a cooling system, which can further reduce the discomfort during treatment and make patients feel more comfortable during treatment.

3. Wide range of skin colors

Compared with lasers of certain wavelengths, the 808nm laser hair removal device has a wider range of applications for different skin colors. On skin with lighter and darker skin colors, the 808nm laser can produce better hair removal effects, especially for dark hair. This is because melanin has a strong absorption capacity for lasers, and the 808nm laser wavelength can be efficiently absorbed by melanin, bringing a stronger photothermal effect.

Other medical and cosmetic applications of 808nm laser

In addition to its application in laser hair removal machines, the 808nm laser hair removal device is also widely used in other medical and cosmetic fields. Its strong penetration and selective effects on different tissues make it also have important application value in skin treatment, hair treatment, etc.

1. Skin treatment

The 808nm laser hair removal device can also be used to treat some skin problems, especially in skin rejuvenation and repair. Its thermal effect can promote the production of collagen in the skin, help the skin restore elasticity and firmness, and improve fine lines and sagging. In addition, 808nm laser can also be used to treat problems such as pigmentation and age spots, because it can effectively promote skin metabolism and help remove pigments.

Through 808nm laser treatment, the blood circulation of the skin will also be improved, resulting in a smoother and more even skin tone. This makes 808nm laser one of the important means in modern beauty treatment.

2. Hair treatment other than hair removal

In addition to common hair removal treatments, 808nm laser hair removal device can also be used to treat some hair problems, such as folliculitis and excessive hair growth. For some patients, folliculitis may cause abnormal hair growth and even the formation of pustules. 808nm laser can effectively help restore normal hair growth by reducing inflammation and reducing swelling of hair follicles.

3. Treatment of vascular diseases

The 808nm laser hair removal device is also widely used to treat certain vascular diseases. For example, lasers can act on blood vessels through thermal effects to help treat varicose veins, spider nevi and other diseases. By changing the temperature in the blood vessels, 808nm lasers can effectively promote vasoconstriction, thereby improving blood flow and vascular problems.

4. Ophthalmic treatment

In the field of ophthalmology, 808nm lasers are also used to treat some vision problems. Because 808nm lasers have strong penetration and precision, they can be used to treat some corneal diseases, especially in surgical procedures such as laser correction of myopia. 808nm lasers can effectively reshape the shape of the cornea and improve visual effects.

What are the advantages of 808nm laser hair removal device?

The wide application of 808nm laser hair removal device stems from its many advantages, especially its application in laser hair removal machines, which is due to the following characteristics:

1. High efficiency

808nm laser hair removal device can penetrate deep into the skin, accurately irradiate the hair follicles, and has a high energy conversion efficiency, which can effectively destroy the hair follicles and inhibit hair regeneration. The treatment cycle is short and the effect is significant.

2. Safety

Compared with lasers of other wavelengths, 808nm lasers are less harmful to the skin. Its selective effect allows the laser energy to act only on the hair follicles without causing excessive damage to the surrounding skin tissue, thereby reducing side effects such as redness, swelling, and burns after treatment.

3. Wide applicability

808nm laser hair removal device is suitable for all skin types, especially for dark hair. Its applicability to different skin colors allows more people to benefit from this technology.

4. Comfortability

The treatment process of 808nm laser hair removal device is relatively comfortable. The cooling device equipped with modern laser hair removal machines can effectively reduce the discomfort during treatment, making the patient more relaxed during the treatment.
