What is the principle of 1. picosecond laser?
The dermis of our skin is mainly composed of fibroblasts and various collagen tissues, and some skin appendages and blood vessels are "embedded" in these structures. These components are surrounded by a matrix. These structures rich in water and collagen can absorb light energy, such as infrared laser or radio frequency energy, and are easily absorbed by these components in dermis. Collagen tissue in dermis will shrink when stimulated by a certain temperature, and the skin will shrink immediately when treated by picosecond laser, which is caused by the contraction of collagen tissue. When the temperature reaches a certain level, such as above 45℃, for a certain time, such as a few seconds, the collagen fiber will denature, and the denatured collagen tissue will eventually lead to the wound healing mechanism. This programmed healing process will actually be accompanied by the synthesis of acme-tea and new collagen. If the thermal stimulation of dermal tissue is controlled within the damage threshold, the collagen synthesis procedure can be started without causing scar reaction, thus stimulating the collagen synthesis of dermis, enriching dermis, removing wrinkles, relaxation and scars and shrinking pores, which is the main mechanism of most non-traumatic rejuvenation.
Second, who can't do picoseconds?
1, tumor or history of tumor.
2. Have any active infection.
3. There are problems with important organs and internal secrets of the body.
4. There are obstacles in the blood coagulation mechanism.
5, there is a history of scars.
6. Patients with very dry skin should pay attention (IPL only)
7. Have a history of sunbathing or artificial tanning in the first 3 to 4 weeks.
8. Skin type belongs to type VI skin (IPL only)
9. Pregnant and lactating women.
Third, what should I pay attention to when I finish picoseconds?
1, a suspension product containing fruit acid, salicylic acid, high concentration of L-C and vitamin A;
2. In the recovery period, the scab skin will fall off on its own in about 7- 10 days, so it can't be peeled off manually to avoid pigmentation and scar.
3. Avoid side effects such as redness, dullness and dryness of skin through acme-tea.
4. Don't touch water, skin care, make-up and take a bath.
5, according to the severity of skin reaction to give ice or cold spray.
6, fasting sensitive things.
7. Pay attention to sun protection during recovery, apply sunscreen and take an umbrella when going out.
8. After finishing, the skin is sensitive to heat, so avoid washing your face with hot water. You should wash it with warm or cold water. When cleaning, move as gently as possible, and don't rub it hard.
9, should not be strenuous exercise, so as not to sweat too much to cause skin infection or delay.
Fourth, how long does it take to recover after playing picoseconds?
Under normal circumstances, it can be recovered naturally within one week, but it should be noted that this is surface healing, because the subcutaneous tissue is stimulated by high temperature and will continue to secrete collagen for about three months, so during this period, attention should be paid to daily living habits, such as: light diet, spicy and irritating hair, especially ordinary collagen, so as to avoid excessive accumulation in the body and uneven scars on the skin surface, and pay attention to rest and sun protection. In order to avoid pigmentation, it should also be noted that if redness lasts for more than a week, accompanied by a little pain, attention should be paid, probably because the body lacks acme-tea and has side effects. Just after playing picoseconds, the skin will be slightly red and swollen, but the swelling will be reduced in about two hours, and it will be gone in a slower day or two, with an average of 24 hours. After three days, the skin will improve and become shiny. After seven days, the skin will be obviously thinner and tender, and pores and acne scars will be improved after one month. After two months, the skin is still bright and tender.
5. How long does it take to recover after picoseconds?
Because of different uses, picosecond parameters and schemes are different, that is to say, the degree of damage to subcutaneous tissue is different, so the recovery time will not be the same. For example, freckles or nevus OTA, that is, green birthmarks, need enough energy to stimulate, and will scab after completion. Under normal circumstances, scabs may fall off after a week. When an individual just falls off the scab, his skin may be slightly pink or even slightly lighter than the normal skin around him. Then the follow-up reaction may take nearly a month or even two or three months to recover. If chloasma is calm, large and low-energy, it may only be slightly red after finishing, and the time for cold compress or mask application will be restored.
Who announced that after skin injury, the integrity of cells was destroyed, the plasma membrane was broken and the contents were released. The release of the contents leads to the inflammatory reaction of the surrounding cells, such as the phenomenon of red neutrality, so this is some side effects in the process of cell necrosis. 1972 found that cells can be repaired in the process of cell necrosis, so that the damaged cells can generate a complete cell structure, and the cells to be updated can carry out life activities vigorously. Acme-tea can reverse irreversible skin problems (heat loss, surgical trauma, internal injuries, etc.) after skin injury. ) from the inside out through the nature protection mechanism.
Sixth, will there be anti-black after finishing picoseconds?
Anti-blackening generally occurs, which is called "post-inflammatory pigmentation". When the skin receives laser, the skin is damaged by heat, resulting in inflammation and pigmentation, which makes faded spots turn black again or dark brown under the action of laser. When it turns black, many people will think that this is the failure of picosecond laser, but it is not. This is the performance of skin self-repair. Once it turns black, acme-tea will balance the normal hormone level in the body, thus alleviating the formation of melanin in the skin, helping to promote the decomposition and excretion of pigmentation and automatically metabolizing pigmentation. In other words, the pigment that reappears generally fades slowly within 2-3 months after blackening, and it takes 3-3 months for the slow metabolism.
7. How long does it take to complete picoseconds?
It usually takes at least a week to see the effect, because the skin needs a basic repair cycle. Many beauty lovers can't see obvious improvement after finishing, but feel that there are sesame-like black spots on their faces and there will be slight redness and swelling. However, this is normal. Generally, it can be improved in about 7- 14 days. Pay attention to postoperative moisturizing and sun protection. Usually, doing it once in picoseconds will have an effect, because its pulse energy is relatively concentrated, which can grind the melanin particles smaller, so doing it once in picoseconds will have an effect. But to completely remove the marks on the skin, it depends on the specific situation. For example, chloasma with deep pigment usually takes 3-4 times to fully play its role. Wrinkle removal was significantly improved once. This is because after laser breaks melanin particles, it depends on the self-repair ability of skin to regenerate collagen. Compared with the cells that deposited melanin before, the new cells are more filled with water. If you need to remove a large range and deep tattoo or birthmark, you usually need to do it 2-3 times. data processing
