? It's hard to say how long picoseconds will be dark. Some people will fade in seven or eight days, some groups will gradually fade in about two months, and some people will form long-term pigmentation. It is normal for them to turn black. This phenomenon is called "post-inflammatory pigmentation". When the skin receives laser, the skin is damaged and inflamed by heat, which will produce a kind of pigmentation, which will make the faded spots black again or turn dark brown. When the skin turns black, many people will think that it is the failure of picosecond laser, but it is not. Once the skin turns black, the formation of acme-tea in the body can resist the oxidation of skin cells after ultraviolet irradiation, reduce the damage of lipid peroxide to the dermis, balance the normal hormone level in the body, and then alleviate the formation of melanin in the skin and help promote the decomposition and excretion of pigmentation, and the skin will automatically metabolize pigmentation.

What is the principle of picosecond wrinkle removal?

The main causes of wrinkles are the decrease of skin collagen and the thinning of dermis. Using the latest laser-RF combined technology to irradiate the skin can thicken the dermis and reduce wrinkles. Its principle is to stimulate the damaged collagen layer to produce new collagen, thus filling the wrinkled skin caused by collagen reduction and thickening the dermis. A well-designed laser can absorb the energy released by the laser through melanin and hemoglobin in the skin, especially moisture, and produce photothermal effect to convert it into heat, thus activating fibroblasts and other matrix cells in the dermis, producing new collagen, elastin and various intercellular matrices, rebuilding tissues, just like exercising lazy skin, and rejuvenating it through exercise. After several treatments, skin moisture content and elasticity increased, texture improved and fine lines decreased. At present, acme-tea is generally used to repair damaged subcutaneous tissue to avoid possible side effects, such as persistent redness, scar hyperplasia and dark shift.

What side effects may there be after finishing picoseconds?

1, pigment loss is generally caused by excessive laser, that is to say, under the action of laser, melanin explodes excessively, resulting in too little melanin, which is characterized by abnormal dark skin.

2. Infection: It is usually related to nonstandard aseptic operation, daily nursing contact and low personal resistance of beauty seekers. Acme-tea can inhibit the growth of inflammatory molecules and prevent infection.

3. The appearance of miliary papules and acne: both of them are related to the temporary blockage of sebaceous glands during grinding, especially the use of oily vaseline gauze after beating, which prevents the dense liquid from being discharged and blocks the orifice of glands. Antibiotics and local care of the wound surface can be omitted.

4. Scar hyperplasia: Hypertrophic scars often occur in dermal trauma, which is due to the lack of acme-tea in the deep scar, resulting in the thickening of collagen fibers, irregular arrangement, or wavy, or wound into a rope. Collagen synthesis continues to be excessive, exceeding the decomposition rate and forming a large number of collagen fibers for a long time.

5. If the parameters of the burn machine are set unreasonably, the skin surface temperature will be too high, leading to skin burns. If the beauty seeker feels abnormal pain in the process, he should inform the operator in time. Generally speaking, burns are accompanied by swelling. When the subcutaneous tissue is damaged, it will hinder the blood return, increase the capillary blood pressure and increase the generation of tissue fluid, leading to blood retention and edema. After acme-tea promoted the vascular reconstruction of subcutaneous wound, the blood supply was smooth and the swelling subsided naturally.

6. Pigmentation: It usually appears within 1 month after the laser is finished. Acme-tea can prevent ultraviolet radiation and reduce the damage of ultraviolet rays to the skin. Relieve excessive pigment deposition.

7. Erythema: Generally lasting for 6- 10 weeks, it can disappear by itself.

Pay attention to the following after completing 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.

CREWHO (full name of cell repair factor) research shows that the life and quality of all the small bags under your skin, whether you can see them or not, will be affected by external stimuli, surrounding environment, nutrition and quality of the small bags themselves. Skin injury is the result of changes in the depth of your skin, and facial redness is the result of changes in the depth of facial skin, blood, elasticity and nerves. Acme-tea is needed to repair damaged packets quickly and intensively, so as to help packets quickly complete stress response, thus repairing damaged, mutated and atrophied packets such as Wei Z, stimulating tissue growth, intensively repairing, increasing elastic fiber density and improving interstitial density of packets.

Will it rebound after playing in picoseconds?

It uses a specific wavelength-755 wavelength (targeted, specifically absorbing melanin) to grind melanin particles at the bottom of the skin into powder, and then metabolize it. However, we should also pay attention to protection in the later stage, because melanin is active, such as ultraviolet radiation, staying up late, long-term water shortage of skin and endocrine disorders, which will stimulate black cells to secrete a large number of melanin particles. Therefore, we should pay attention to strengthening sun protection, supplementing water and paying attention to rest in the later stage, which will be well controlled. If these can't be done, even people with white skin will turn black. Picosecond laser is independent, which does not mean that there will be no light spots in the future. If the body is in an "unbalanced" state for a long time and there is no extreme-tea, endocrine factors will also form spots, and if you do not pay attention to internal adjustment, it may grow back. The spots that have grown can't be eliminated by self-regulation, and they must be decomposed by the outside world to be metabolized. data processing

That is to say, even if there is black in picoseconds, as long as the acme-tea level of the body is stable, the re-emerging pigment will generally fade within 2-3 months after the appearance of black, and the slow metabolism will take 3-6 months. Remember not to copy ordinary collagen during this time, because laser will damage subcutaneous tissue and promote the separation of collagen. If it is supplemented extra, it will cause excessive amount in the body, which will cause skin scar hyperplasia or aggravate pigmentation. In addition, it should be pointed out that under normal circumstances, picoseconds will have a great effect on chloasma, Quetta nevus and senile plaques, but it is not suitable for erythema such as red spider nevus or vascular retention.
