Summer has quietly arrived, sisters, it’s time to wear short-sleeved suspenders again. Many sisters are worried about the excessive hair on their arms, armpits and lips. Don’t worry! ! The editor will solve your problems! !

Talking about hair removal, the common hair removal methods we use in daily life include shaving, waxing, tweezing, chemical hair removal, etc. These methods can be performed by patients themselves, but they can only remove hair on the surface of the skin, and cannot achieve the purpose of permanently removing excess hair. Improper operation also has the risk of pain and burns.

In addition to the above methods, the commonly used hair removal technologies on the market are photon hair removal and laser hair removal. The latter can be further divided into long-pulse emerald laser, Nd:YAG laser and diode laser. Studies have shown that the efficacy and comfort of 808nm diode laser hair removal are better than other lasers.

The 808 semiconductor laser has strong skin penetration, a wide range of energy and pulse width, and better absorption of melanin, which enables better conduction of light and heat, destroying hair follicles, and thus more efficient hair removal.

1. Working principle of diode laser hair removal.

The 808 diode hair removal device targets melanin and selectively acts on the hair follicles, causing their temperature to rise sharply, destroying the hair follicles and their surrounding tissues, thereby destroying the germinal center on which the hair grows. After absorbing the laser, melanin selectively destroys the hair follicles due to the photothermal effect, fundamentally stopping hair growth and achieving a permanent hair removal effect. At the same time, it can avoid damage to the surrounding normal tissues, shrink the pores, and make the skin completely smooth and flawless.

Diode freezing point hair removal is based on selective photothermal action, targeting melanin, and irradiating the skin with light of a specific wavelength. The light energy will be absorbed by the melanin in the skin and then converted into heat energy, thereby destroying the hair follicles, achieving the purpose of hair removal and inhibiting hair growth. At the same time, the so-called “freezing point” refers to the installation of an epidermal cooling system, which has a cooling function, can protect the skin and relieve pain.

The effective penetration depth of the 808nm wavelength can reach the target tissue (dermal papilla) with an appropriate pulse duration, ensuring that the target tissue produces sufficient thermal damage while the surrounding tissue is almost unaffected; the appropriate energy density ensures that sufficient energy output is provided within an appropriate time, which is enough to damage the target tissue while the normal tissue is almost unaffected; appropriate epidermal protection measures ensure sufficient damage to the target tissue while the epidermis is almost unaffected, thereby ensuring the safety of treatment.

2. Knowledge of hair cycle.

2.1 Three growth cycles of hair.

Hair growth is cyclical, including the growth phase (Anagen), the regression phase (Catagen), and the resting phase (Telogen). The hair growth cycles of different parts are not synchronized, and each has its own growth cycle. The principle of laser hair removal is mainly to act on the melanin in the hair follicles, so hair removal is effective for hair in the growth phase, but it has little effect on hair in the regression phase or the resting phase. Therefore, hair removal requires a course of treatment.

• In the growth phase (Anagen): hair growth is active and melanocytes are the most.
• Catagen: hair growth is static, the number of capillaries decreases, the hair papilla atrophies, and melanocytes stop producing melanin.
• Telogen: the hair follicles separate from the hair papilla, and the hair falls off.

2.2 808 diode laser for hair in different cycles.

Act on the skin surface through 808nm laser. The laser passes through the skin until the highest concentration of melanin in the hair shaft is reached.

The light is converted into heat energy, and the hair shaft and most of the hair evaporate instantly. Then the high temperature acts on the hair, destroying the follicular epithelium, and the upper part of the hair disappears.

The hair cycle is divided into three stages – growth phase, decline phase and dormancy phase. The hair follicles in the growth phase contain more melanin, and the hair follicles have the best hair removal effect at this stage, but only 10%-20% of the hair is in the growth phase, so it is necessary to follow the course of treatment to completely remove the hair. In the regression phase, the melanin in the hair follicles is decreasing, and in the resting phase, there is no melanin in the hair follicles. Therefore, laser hair removal should be done at intervals and in several times, so that hair in all periods can be targeted, and the effect achieved will be more satisfactory.

3. What are the commonly used hair removal methods?

Hair removal includes physical hair removal, chemical hair removal and laser hair removal. Physical hair removal, such as plucking, shaving, waxing, and chemical hair removal (such as depilatory cream), will grow back. After spending time, energy and money, the hair is still there. These methods are only temporary hair removal, and long-term use may make the hair gradually thicker and harder. If you want permanent hair removal, you might as well try laser hair removal, among which diode freezing point hair removal is currently the most popular hair removal method.

3.1 Physical hair removal: waxing and razor hair removal.

It is more commonly used to remove armpit hair at home, and the advantage is that it is cheap and easy to operate. However, the durability is average, and it will grow back later, and the hair will grow harder and harder.

3.2 Chemical hair removal: depilatory cream, depilatory mousse.

Compared with physical hair removal, depilatory cream is more gentle, not as simple and rough as depilatory knives, but it is also easy to cause skin allergies.

Whether it is a depilatory cream or a depilatory mousse, the ingredients used are basically potassium thioglycolate or calcium thioglycolate. Their working principle is to corrode the hair through these ingredients, causing the epidermal hair to fall off naturally, but it has no effect on the root hair follicles, so it cannot be permanently depilated, and the subsequent hair will still grow out.
Moreover, for people with sensitive skin, chemical depilation is a “dangerous thing”. Itching and redness are trivial. If the chemical ingredients stimulate the hair follicles, making the hair grow more vigorously, or inflammation occurs, contact dermatitis will not be worth the loss.

Therefore, sisters who want to use depilatory cream are only recommended for temporary first aid once, and sensitive skin is not recommended.

3.3 Photoelectric hair removal: home depilatory device, laser/freezing point hair removal.

The principle of home depilatory devices and laser hair removal is through the selective thermal effect of light. Through strong light penetrating into the skin, it touches the melanin in the hair follicles and is absorbed, and then converted into heat energy, which instantly inactivates the hair matrix cells and heats up, carbonizes, loses the ability to supply hair, and inhibits the regeneration of hair follicles.

The biggest difference between the two is in power and energy. Hospitals use large hair removal machines, so the power can even reach 500~600 watts, while home hair removal devices are small appliances, usually 20~30 watts, so there is still a difference.

Freezing point hair removal is an upgraded version of laser hair removal. In fact, it is based on laser hair removal with a cooling head device to reduce damage to the skin. The mainstream hair removal on the market now is this type.

Because the power is different, the energy is also different, and the energy determines the effect and intensity of hair removal. This is why some people think that going to a hospital or clinic for hair removal is better.

4. 808nm laser hair removal process.

The diode laser uses a wavelength of 808nm to effectively penetrate deep into the target tissue, and the energy output is enough to destroy the hair papilla without affecting normal tissue. Therefore, whether it is golden hair and white skin, brown hair and brown skin, or black hair and yellow skin, it can remove hair of any hair color, skin color, or ethnicity.

4.1 Operation method.

Flash sliding operation.

4.2 Hair removal area.

Hair in precise facial parts; hair in sensitive parts of the armpits and bikini; large areas of hair on the limbs and trunk can be easily removed.

4.3 Hair removal feeling.

There is a slight tingling sensation, and you can feel the heat energy of the light entering the subcutaneous tissue.

4.4 Hair removal time and treatment course.

20-40 minutes for the whole body; 10-20 minutes for the hairline; 15-20 minutes for leg hair; 10 minutes for underarm hair. 3-5 times can achieve the ideal effect.

4.5 Hair removal effect.

The hair is curly and has a burning smell, and then it is metabolized and falls off by itself, or it is directly pulled out by hand. Or the hair follicles bulge slightly.

5. Indications and contraindications of diode hair removal.

5.1 Indications of diode laser.

Diode freezing point hair removal is suitable for excess hair on all parts of the body, such as underarms, arms, legs, bikini line, etc. Whether male or female, as long as you feel that your hair affects your appearance or brings inconvenience to your life, you can consider using this hair removal method.

5.2 Contraindications of diode laser.

Although diode freezing point hair removal is safer, there are still some contraindications that need to be noted. For example, people with photosensitive skin diseases, skin cancer, pregnant women, breastfeeding women, and people who have been exposed to the sun recently are not recommended to undergo this type of hair removal treatment. In addition, patients with serious heart disease, hypertension and other diseases also need to choose carefully under the advice of a doctor.

6. Features and advantages of 808 nm diode laser hair removal.

6.1 Dual pulse technology.

A special dual pulse design is used — preheating pulse and heating pulse. The preheating pulse safely heats the hair follicles and surrounding tissues to 40°C; the heating pulse selectively raises the temperature of the hair follicles to 50°C, accurately destroying the hair follicles without damaging the adjacent tissues, thereby achieving a safe and lasting hair removal effect.

6.2 Contact cooling technology.

The rare sapphire treatment bald head, the window close to the skin to cool the local area to 5°C, effectively protects the normal skin from damage, the entire hair removal process is cool and painless, and greatly improves the patient’s comfort.

6.3 Sliding technology.

ON-Motion fast sliding technology: The sliding mode is used to cover a large area of ​​the treatment area to ensure rapid hair removal.

6.4 10HZ stable high frequency.

The vertical stacked array semiconductor laser combined with microchannel cooling technology ensures that the laser is very stable at a high frequency of 10Hz.

6.5 Four outstanding features.

1. High efficiency: Semiconductor freezing point hair removal can quickly remove excess hair, and the effect is more obvious compared to traditional hair removal methods.
2. Safety: This technology uses an advanced cooling system to protect the skin from damage and reduce pain during hair removal.
3. Durable: Through multiple treatments, it can effectively inhibit hair growth and achieve long-term hair removal effects.
4.  Non-invasive: Compared with traditional hair removal surgery, semiconductor freezing point hair removal does not require surgery, has a shorter recovery period, and does not affect daily life.

7. Precautions after hair removal.

After the hair removal treatment, although the skin will not show obvious redness and swelling, you still need to avoid hot water washing and sun exposure for a few days after hair removal, and keep the treatment area moisturized.

The interval between each hair removal treatment is about 1-1.5 months. In order to ensure the best treatment effect, you cannot shave or pull out new hair by yourself during the treatment period to avoid stimulating the activity of hair follicles.

7.1 Avoid sun exposure.

The skin after treatment is more sensitive and needs to be avoided from direct sunlight to avoid pigmentation.

7.2 Keep the skin clean.

Keep the hair removal area clean after surgery to avoid infection.

7.3 Use skin care products.

Mild skin care products can be used to moisturize the skin and relieve dryness and itching symptoms.

7.4 Follow the doctor’s advice.

Carry out follow-up treatment and care according to the doctor’s advice to achieve the best hair removal effect.

8. FAQs about 808nm diode laser hair removal.

Q: Is 808 diode freezing point hair removal painless and safe?
A: 808 semiconductor freezing point painless hair removal is a very safe laser hair removal method, which is highly professional, has no side effects on the human body, has almost no effect on the skin, and also has the effect of whitening and skin rejuvenation.

Q: Can hair removal be completely removed in one time?
A: Laser hair removal generally requires three to six times to remove the hair completely.
There are two reasons:
1. Most hair follicles are bundled together in groups of three and open in the same pore. A hair in a pore grows from one of the three follicles in the group below it, so one treatment can only destroy one follicle in a group;
2. Hair growth must go through the growth period, regression period, and resting period. The freezing point 808 painless hair removal is 75% effective in the growth period, 25% in the regression period, and almost ineffective in the rest period.

Q: Will hair removal affect the sweating function?
A: Safe 808 diode laser freezing point painless hair removal will not affect sweating.
Because sweating mainly depends on small sweat glands, and the small sweat glands are not in the hair follicles, and 808 painless hair removal is to sweep the hair follicles, it will not hurt the sweat glands, so it will not affect the body’s metabolism and sweating.
Its principle is the principle of selective thermodynamics: that is, the selected wavelength only acts on melanin, not on normal skin tissue; the selected pulse width only acts on melanin in the hair follicles, not on melanin in the basal layer of the skin.

Q: Does diode hair removal damage the skin?
A: No damage.
The human skin is a relatively transparent structure. Plastic surgery experts have found in clinical experiments that in front of powerful lasers, the skin is simply a transparent cellophane, so the laser can penetrate the skin very smoothly and reach the hair follicles. 808 semiconductors as a single 808 wavelength can remove hair more accurately.
Because there are a lot of melanin in the hair follicles, they can preferentially absorb a large amount of laser energy and eventually convert it into heat energy, which increases the temperature of the hair follicles and achieves the purpose of destroying the function of the hair follicles.
In this process, the skin itself will not be damaged because it relatively does not absorb laser energy, or absorbs very little laser energy.

Q: Will the hair become darker after laser hair removal?
A: No!
The remaining hair after laser or strong light treatment will become thinner and lighter in color.
For people who use shaving, plucking, depilatory cream, waxing paper, etc. for a long time, their hair will gradually become thicker, harder and darker.
