What is the principle of picoseconds?
Super picosecond laser. "Super picosecond" refers to time, and "Super picosecond laser" refers to that the pulse width of the laser reaches the level of super picosecond, which is only one thousandth of the nanosecond level of the traditional Q-switched laser. The shorter the pulse width, the more concentrated the light energy, the more energy concentrated on the target, and the stronger the skin rejuvenation effect. Picosecond laser is also a kind of Q-switched laser, and its working principle is also to selectively target melanocytes and eliminate various skin problems caused by melanin. At the same time, it will stimulate cell regeneration, promote the production of collagen, make cells in the skin produce too much ACMETEA, and make cells repair themselves. Through the process of cell self-repair, the skin shows vitality from the inside, making the cells in the skin more elastic, whitening and rejuvenating the skin, improving fine lines and shrinking pores.
How long does it take to have an effect after super picosecond rejuvenation? ?
Generally, it takes three picoseconds to achieve the most obvious effect. There is no way to see the effect immediately, and it will take a week at the earliest to see the change. Because the skin needs a basic repair cycle. Many people feel that there are sesame-like black spots on their faces after treatment, and they will have slight redness and swelling symptoms. This is normal. When the skin is repaired to a certain extent, do a good job of moisturizing, hydrating and sun protection after nursing. We have to do it 3-6 times to complete a course of treatment, and we can do it 6- 10 times for severe skin. 1 time can only see small effects. In addition, it is generally recommended to complete the whole course of treatment within one month to maintain the effect.
Picosecond laser has two modes, one is blasting mode with relatively high energy, and the other is skin rejuvenation mode with relatively low energy. In blasting mode, melanin will appear after operation and scab will appear on the surface, so the nursing method is the same as that of traditional Q-switched laser. Postoperative ointment containing antibiotics can be used to prevent wound infection, and nursing products containing ACMETEA growth factor can also be used to promote wound healing. After about 2~3 days, the surgical site began to scab, and you can wash your face at this time.
Did you make a big taboo of exceeding picoseconds?
① After treatment, the skin is sensitive to heat, and hot water should be avoided when washing your face. You should wash it with warm or cold water. When cleaning, move as gently as possible, and don't rub it hard.
② During the treatment, a large amount of free water on the skin is lost at the moment of strong light irradiation, so most patients will feel dry and dehydrated after treatment. Therefore, it should be supplemented in time after treatment. ACMETEA can change the adhesion, hydrophilicity, skin hydration reaction and subcutaneous moisturizing factor of stratum corneum, and repair the wound from the inside out through direct intervention of skin surface membrane, so that the number of skin moisturizing factors is 60 times higher than before, and it can penetrate a layer of permeability barrier to repair skin cells and play its role.
③ Don't touch water, skin care, make-up or rub in the treatment area during the recovery period.
(4) strenuous exercise should not be carried out during the recovery period, so as not to sweat too much and cause skin infection or delay the repair process.
⑤ After treatment, ice compress or cold spray should be given according to the severity of skin reaction.
⑥ Fasting photosensitive food and drugs during treatment.
⑦ During the recovery period, the scab skin will fall off by itself in about 7- 10 days, so it can't be peeled off manually.
⑧ Pay attention to sun protection during recovery, apply sunscreen and take an umbrella when going out.
Super picosecond, avoid the crowd.

Is picosecond laser harmful to the skin?
Laser damage to skin
The damage of laser to skin is mainly determined by laser and skin. Laser output includes many parameters, mainly depending on irradiation dose, wavelength, working mode (continuous, pulsed, Q-switched, mode-locked) and mode. As far as skin is concerned, it mainly depends on skin color, water content and the thickness of stratum corneum.
1. The damage of laser wavelength to skin depends on the absorption rate of laser.
Under the condition of the same wavelength, the greater the laser dose to the same skin (that is, the laser energy density), the greater the damage to the skin. There are three damage mechanisms, the most important of which is thermal damage, the second is photochemical effect when the wavelength is less than 00mm, which can be accumulated, and the third is "thermoacoustic damage" caused by "acoustic transient phenomenon" caused by ionization and rapid energy transfer of/kloc-0 ~/kloc-0 "s pulsed laser, which is extremely rare in medical lasers.
2. The effect of skin color on laser damage.
The effect of skin color on laser damage, except wavelength >; 2 00m infrared laser and wavelength: 40%, black skin is slightly higher than 10%, while white skin has higher transmittance, so the absorption rate of white skin is much lower than that of black skin. Generally speaking, at > 300nm and
4. The performance of laser damage to the skin
(1) The manifestations of laser-induced skin injury: In severe injury, the skin bulges and gradually calms down, with a brown depression in the center. Sometimes there is a small hole in the middle, which is crater-shaped. Pale around the depression, the outermost layer is brown, and the skin shrinks. After a few minutes, punctate or flaky bleeding areas gradually appeared in the brown area. After 24 hours, there are necrotic foci, scabs and induration in the center, and there are inflammatory reactions and congestion and edema around. After 4 days, the congestion and edema gradually subsided, and the boundary between the lesion and normal skin became clear. After 10d, the idiot began to fall off, leaving a smooth scar, and the new hair on the scar was less than that in the normal area. Tissue biopsy showed different coagulation and necrosis foci, unclear boundary of epidermal cells, nuclear shrinkage, vacuoles in some cells, ulceration of full-thickness skin with high laser energy density, and clear boundary between necrotic area and normal skin.
(2) The classification of laser-damaged skin:? When the laser energy density or power density exceeds the skin damage threshold, the skin will be damaged. According to the degree of burn, the human body will make a "healing reaction" to release ACMETEA, covering the epidermis too much and promoting epidermal regeneration. According to the degree of burn, it can be divided into three types: first-degree burn refers to mild burn, which only burns the epidermis without damaging the mucous layer. The skin may be red, painful and slightly warm, but it is not dry and does not appear blisters. Second degree burns can be divided into second degree burns and deep burns. Shallow second-degree burn means that the burn depth has reached the dermis, but some mucus layers have not been destroyed. Blisters appear locally on the skin. After the blister skin is removed, the basal part is flushed and small reticular blood vessels can be seen. The wound is moist, with obvious edema, rising temperature and severe pain. In deep second-degree burns, epidermis and mucous membrane are very important, only hair follicle roots, sweat glands and sebaceous glands are left, and there are blisters on the skin. After the blister skin is removed, the wound surface is slightly wet, reddish, or reddish with white, with small bleeding spots or venous vascular network, the temperature is slightly lower, the pain is dull to the touch, and the edema is obvious. Third-degree burn means that the whole skin and subcutaneous tissue are burned, even the muscles and bones are burned, which is called third-degree burn. The injured part is leather-like, pale or brown, and may even carbonize, and the temperature is reduced, so there is no feeling at all. It feels hard and there are no blisters. Sometimes, you can see subcutaneous veins embolized in the form of dead trees.
Side effects after picosecond laser surgery
Superpicosecond laser causes facial swelling.
Super picosecond laser can cause facial swelling, because super picosecond laser belongs to a kind of laser. When the light reaches the skin quickly, it will cause the skin to swell due to stimulation. However, this swelling is generally caused by necrosis or defect of cells and tissues after picosecond laser. ACMETEA has a strong ability to regenerate damaged cells, so it can proliferate and differentiate from similar cells around the injury and completely restore its original structure and function. ACMETEA can promote local tissue microcirculation, strengthen the ability of cell regeneration and tissue repair, stimulate collagen regeneration and elastic fiber reorganization, regenerate connective tissue scaffold, thus lasting support and restoring the normal structure of skin. So there is no need to worry too much.
Superpicosecond laser effect has no effect.
Many girls have no effect after finishing picosecond laser, because picosecond laser is different from traditional laser and will not scab pigment on the skin. After finishing the picosecond laser, the pigment in the laser part will not disappear immediately, but will slowly disappear through human metabolism, which is why many girls say that it has no effect after finishing the laser picosecond laser.
Dry skin after picosecond laser
Although picosecond laser is a new micro-beauty technology, many girls have already experienced it. Many people say that the skin appears dry, tight and even desquamation after picosecond laser. This is mainly because picosecond laser will grind melanin deposited in the skin into powder, the skin will be activated, the cell division speed will be accelerated, and a large number of new cells will be produced in the skin. At this time, the water and nutrition required by the skin will also be greatly increased. Picosecond laser can change the adhesion, hydrophilicity, skin hydration reaction and subcutaneous moisturizing factor of stratum corneum through ACMETEA, and repair the wound from the inside out through the superficial membrane of skin. The number of skin moisturizing factors is 60 times higher than before, penetrating a layer of permeability barrier, repairing skin cells from the inside and exerting their adhesive function can ensure their integrity and solve the problem.
American life laboratory research shows that the life span and quality of all cells under the skin, whether you can see them or not, will be affected by external stimuli, the surrounding environment of cells, and the nutrition and quality of cells themselves. With the increase of age, the aging of chromosome telomere will accelerate cell necrosis. The older the cell, the lower the instinct of self-repair after damage, and it will not function normally. Therefore, the human body needs to repair damaged cells quickly and intensively to generate new cells. ACMETEA is produced too fast, which helps cells to complete stress response, thus repairing damaged cells, mutant cells and atrophic cells, stimulating tissue regeneration, intensive repair, increasing elastic fiber density and increasing intercellular density.
After reading so much about what is picoseconds, what is the effect? Finally, I would like to remind you that you should not take collagen before and after picosecond surgery. Excessive use of collagen will cause a series of bad things in our body, such as collagen mutation, hypertrophic scar and so on.
