1. Principle
808nm means that the wavelength of the laser is 808 nanometers in length. The best laser hair removal wavelength has little absorption of hemoglobin and water. Lasers of specific wavelengths can only be selectively absorbed by the target color base. In laser hair removal, hair follicles and hair shafts The melanin in the medium is the target color base. It absorbs light energy and generates high temperature. When the temperature reaches about 45°C, it is kept warm, so that the hair follicle generates heat, and the penetration depth can reach the target tissue (hair papilla), instead of relying solely on the hair shaft. Conductive, so it has a good effect on small and light-colored hair, and the sapphire contact cooling treatment head is used to cool the skin temperature to -5℃～5℃, which can effectively reduce the skin temperature before, during and after laser irradiation , To make the treatment and cooling proceed simultaneously, protect the normal skin tissues from harm, feel more comfortable, do not damage the surrounding tissues, only destroy the key role of the dermal papilla, prevent hair growth, achieve the effect of permanent hair removal, but do not damage 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 growth phase (anagen), catagen phase (catagen) and static (telogen). In the anagen phase, the hair matrix cells divide rapidly, and the melanin is the most in this phase, so they are extremely sensitive to laser; in the anagen phase, the hair matrix is degraded and the hair papilla atrophy; the hair follicle is separated from the hair papilla in the quiescent phase, and the hair falls off.
1. Because the laser has no obvious effect on the hair in the anagen phase and the static phase, the laser can only work after these hairs are transferred to the growth phase. Therefore, laser hair removal requires multiple treatments for the effect to be obvious.
2. If the proportion of hair in a certain part in the growth phase is small, the number of treatments should be increased. On the contrary, the number of treatments can be reduced.
3. Due to the different growth cycles of different parts of the hair, the interval between each treatment is also different. If the head hair has a relatively short resting period, the interval can be as short as 1 month; the trunk and limbs have a relatively long resting period, so the treatment interval is about 2 months.
4. If the hair follicle density in a certain part is too high, the laser energy should be appropriately reduced during treatment.
Two, installation
1. It is best to keep the box for one year, so as not to use it for future maintenance
2. Probe installation
3. The instrument must be turned on with water, otherwise it will burn the probe, add Watson's distilled water, (the water must flow smoothly, the treatment tip will be burnt if the water is not filled)
4. Change the water every 1 month. When changing the water, open the drain to allow the old water to flow out, then cover the drain and add water again, as in step 3.
3. Preoperative inspection
1. Ask the guests whether they have photosensitivity (solar rash, lupus erythematosus), a small number of people will be red, swollen and itchy in the sun, this phenomenon can not be used as an optical instrument;
2. Those who have done optical instruments on the same part within one month can do it after one month;
3. Do not wear jewelry, watches and other accessories during the treatment;
4. It is forbidden for pregnant women, breastfeeding period, heart disease, severe disease patients, or those with open wounds;
5. Those who have undergone plastic surgery can receive treatment as long as they recover well
6. Skin malignant tumors or precancerous lesions
7. People who have been tanned or sunburned recently or plan to spend a holiday in the sun
8. Acute skin infection (herpes, frostbite) or various skin lesions
9. Those who have recently taken photosensitizing drugs (within one month)
10. Thin (referring to peeling) dry skin
11. Patients with cardiac pacemakers.
12. Patients with metal in the body (including orthodontic appliances), and the parts of the face with prosthesis, bypass and not beat
13. Skin that is in the allergic period
14. Cannot be done if there is a tattoo but not the part
15. Go around the part with moles
Fourth, the project process
Operating time: 20 minutes
1. Any part of the operation must be shaved, and the ones that do not need to be shaved are very clean. It is better to leave a little burr to remove the hair; or ask the guest to shave the hair completely at home two or three days in advance, and a little burr will grow in two days. Come and take it off; (3 minutes)
2. Clean the operating part, wipe it with pure water or use a physiological wipe (1 minute)
3. Apply gel, apply a thin layer of gel like coin thickness, which plays a role of heat dissipation and lubrication. After the gel is refrigerated and then applied, it can improve the comfort; 1 minute)
4. Adjust the parameters, start from low energy (for example, adjust from 5 or so)
5. Test, test two shots when the operation is unstable, to see if the parameters are appropriate; the hair removal energy should be adjusted until the guest feels a slight tingling sensation or a slight tingling sensation, the best effect; (2 minutes)
6. Adjust the energy so that there is a slight tingling sensation in the customer's hair removal area
7. Start the formal operation, the probe should be close to the skin, and each part should be operated 8 or 10 times in an orderly manner
Manipulate large parts (such as back, arms, and thighs): You can slide the probe close to the skin, press the handle switch to emit light, and then start to push it in sequence at an even speed, and operate it more than 5 times. (Do not stay on the same skin after exposure, otherwise it will burn easily) (10-15 minutes)
Manipulate small parts (such as: hairline, lip hair, etc.): use a stamping technique to hold the probe close to the skin, press the handle switch to emit light, then light up and then send it again, like a stamp, During the operation, the first spot should be close to the next spot to ensure that every place is hit, and the operation is about 8 times. (5-10 minutes)
8. Cleaning: After the operation, hang off the gel paper towel with the mask stick to wipe all the gels, and then wipe it with normal saline to complete the operation; (1 minute)
Operating skills:
If you want the effect to be faster and better, you can call it a few more times during the operation. If the skin is a little red, then use tweezers to dial out some burrs on the spot. If you can’t dial it on the spot, you can ask the customer to go home in about 7-10 days and you can dial it easily. Just drop. This method of operation will reduce the number of treatments, but it is only suitable for thick hair areas, such as underarms, hairline, thicker legs, etc.
Five, parameters
1. Energy: starting from 3, the adjustment is generally around 6-8, according to the customer's feelings (adjusted to a slight tingling sensation, or a slight tingling sensation)
2. Frequency: 2
3. Course of treatment: once a month, or once a month and a half
Coarse: 3-4 times
Fine hair: 5-8 times
Six, postoperative care
1. If there is a strong feeling of heat, it is recommended to give customers ice packs;
2. Instruct customers to take care of sunscreen within 30 days after taking off, wear sunscreen, open umbrella, etc.;
3. The depilated area should not be exposed to hot water for 6 hours;
4. Do not use sauna, hot spring or swimming within 7 days;
5. It is recommended to put on makeup after 1 day;
6. If there is a little redness or inflammation (rarely this happens), it may be that the probe is not cleaned and infected or the skin is not clean, or the customer has folliculitis, photosensitivity, etc., should be iced or applied. Erythromycin ointment. Do not bask in the sun or in a place with high temperature and keep well ventilated.
