808 Speedy Hair Removal Device Installation Introduction and Usage

1. Principle

808nm means that the wavelength of the laser is 808 nanometers, the best wavelength for laser hair removal. It has little absorption by hemoglobin and water. Lasers of a specific wavelength can only be selectively absorbed by the target color base. In laser hair removal, the melanin in the hair follicles and hair shafts is the target color base. It generates high temperature after absorbing light energy. When the temperature reaches about 45°C, it is kept warm to generate heat in the hair follicles. The penetration depth can reach the target tissue (hair papilla) instead of relying solely on hair shaft conduction. Therefore, it has a good effect on fine and light-colored hair. In addition, the sapphire contact cooling treatment head is used to cool the epidermal temperature to -5°C ~ 5°C, which can effectively reduce the epidermal temperature before, during and after laser irradiation, so that treatment and cooling can be carried out simultaneously, protecting normal skin tissue from damage and making people feel more comfortable. It does not hurt the surrounding tissues, but only destroys the key role of the hair papilla, prevents hair growth, and achieves the effect of permanent hair removal, but does not hurt the sweat glands.

808nm laser hair removal can be applied to all parts of the body, such as underarms, arms, legs, hairline, upper lip, face, bikini line, etc.
Hair growth has three phases: anagen, catagen, and telogen. During the anagen phase, the hair matrix cells divide rapidly, and melanin is the most abundant during this phase, so they are extremely sensitive to lasers. During the catagen phase, the hair matrix degenerates and the hair papilla atrophies. During the telogen phase, the hair follicles separate from the hair papilla and the hair falls off. The duration of the telogen phase varies from part to part.
1. Because laser has no obvious effect on hair in the regression phase and resting phase, laser can only work after these hairs enter the growth phase. Therefore, laser hair removal requires multiple treatments to achieve obvious results.
2. If the proportion of hair in the growth phase in a certain area is small, the number of treatments should be increased. Otherwise, the number of treatments can be reduced.
3. Since hair in different parts of the body has different growth cycles, the treatment intervals are also different. For example, the hair on the head has a relatively short resting period, so the interval can be as short as one month; the hair on the trunk and limbs has a relatively long resting period, so the treatment interval is preferably about two months.
4. If the hair follicle density in a certain area is too high, the laser energy should be appropriately reduced during treatment.

2. Installation

1. It is best to keep the box for one year to avoid it being used for maintenance in the future.
2. Probe installation
3. The instrument must be filled with water before it can be turned on, otherwise the probe will be burned. Add distilled water from Watsons (the water must flow smoothly, if it is not filled with water, the treatment gun tip will be burned)
4. Change the water once a month. To change the water, open the drain port, let the old water flow out, then cover the drain port and add water again, as in step 3.

3. Preoperative examination

1. Ask the customer if he/she has photosensitivity (sun rash, lupus erythematosus). A small number of people will get redness, swelling and itching when exposed to the sun. This phenomenon should not be treated with optical instruments;
2. If you have had an optical instrument done on the same part within one month, you can do it one month later;
3. Do not wear jewelry, watches or other accessories during the treatment process;
4. Pregnant women, breastfeeding women, people with heart disease, serious diseases, severe highs, or those with open wounds are prohibited from doing this;
5. People who have undergone plastic surgery can receive treatment as long as they have recovered.
6. Skin malignancies or precancerous lesions
7. People who have recently been tanned or sunburned or are planning to go on vacation in the sun
8. Acute skin infections (herpes, frostbite) or various skin lesions
9. Those who have taken photosensitizing drugs recently (within one month)
10. Thin (referring to skin peeling) dry skin
11. Patients with pacemakers.
12. Patients with metal in their bodies (including dental braces) and prosthetic parts on their faces should avoid surgery.
13. Skin that is in the allergy period
14. Do not do it on areas with tattoos
15. Avoid areas with moles

IV. Project Process

Operation time: 20 minutes
1. All parts of the body must be shaved. It is not necessary to shave them very cleanly. Leaving some burrs will result in better hair removal effect. Or ask the customer to shave the hair completely at home two or three days in advance. After two days, some burrs will grow out and then come back for hair removal. (3 minutes)
2. Clean the operation area, wipe it with pure water or use a physiological wipe (1 minute)
3. Apply gel. Apply a thin layer of gel as thick as a coin to dissipate heat and lubricate. Refrigerate the gel before applying it to improve comfort; 1 minute)
4. Adjust the parameters, start with a low energy level (for example, around 5)
5. Test, try to fire two shots when the operation is unstable to see if the parameters are appropriate; the hair removal energy should be adjusted to the point where the customer feels a slight tingling sensation or a slight stinging sensation for the best effect; (2 minutes)
6. Adjust the energy until the customer feels a slight tingling sensation at the hair removal site.
7. Start the formal operation, keep the probe close to the skin, and operate each part 8 or 10 times in order.
Method for operating large parts (such as back, arms, thighs): Use sliding method, keep the probe close to the skin, press the handle switch to start the light, and then push it in a uniform speed and in sequence. Operate more than 5 times. (Do not stay on the same skin after the light comes out, otherwise it is easy to burn) (10-15 minutes)
Technique for small parts (such as hairline, lip hair, etc.): Use stamping technique, place the probe close to the skin, press the handle switch to emit light, then light up and then light up again, just like stamping. When operating, the first light spot should be close to the next light spot to ensure that every place is hit. Operate about 8 times. (5-10 minutes)
8. Cleaning: After the operation, use the mask stick to hang off the gel tissue and wipe all the gel, then wipe it clean with saline to complete the operation; (1 minute)
Operation tips:
If you want a faster and better effect, you can apply it several times until the skin turns red, and then use tweezers to remove some burrs on the spot. If you can't remove them on the spot, you can ask the customer to go home and remove them easily in about 7-10 days. This method will reduce the number of treatments, but it is only suitable for thick hair areas, such as armpits, hairline, thicker leg hair, etc.

5. Parameters
1. Energy: Start from 3, usually around 6-8, and adjust according to the customer's feelings (adjust to a slight tingling sensation or a slight tingling sensation)
2. Frequency: 2
3. Treatment course: once a month, or once a month and a half
Coarse hair: 3-4 times
Fine hair: 5-8 times

6. Postoperative Care
1. If there is a strong sense of heat, it is recommended to apply ice to the customer;
2. Remind customers to take good sun protection within 30 days after taking off their clothes, apply sunscreen and use an umbrella when going out, etc.;
3. The hair removal area cannot come into contact with hot water for 6 hours;
4. No sauna, hot spring or swimming within 7 days;
5. It is recommended to put on makeup after 1 day;
6. If there are small red spots or inflammation after the operation (this rarely happens), it may be due to infection caused by the probe not being cleaned properly or the skin not being cleaned properly, or the customer has folliculitis, photosensitivity, etc., you should apply ice or erythromycin ointment. Avoid sun exposure or high temperature places, and keep ventilation.
