Loving beauty is human nature. With the improvement of living standards, more and more people pay attention to appearance management and skin care. In the field of medical cosmetology, plastic surgery, injection beauty and laser beauty are the three most popular directions that have attracted much attention. Among them, laser beauty is deeply loved by beauty lovers due to its advantages such as significant efficacy, less trauma, fast recovery and less pain. As one of the mature and reliable laser beauty technologies, picosecond laser has won the favor of many beauty seekers.

PRINCIPLES AND MECHANISMS

Principles of Picosecond Laser

Picosecond is actually a unit of time. Picosecond laser refers to a laser with a pulse width at the picosecond level. Let's do a time conversion. 1 second is equal to 10³ milliseconds, which is equal to 10⁶ microseconds, which is equal to 10⁹ nanoseconds, which is equal to 10¹² picoseconds. It can be seen that the pulse width of a picosecond laser is a full 1000 times faster than that of an ordinary Q-switched laser (nanosecond level).

Melanosomes have a thermal relaxation time (TRT), which is the time required for the temperature of the target structure to drop by 50% after laser irradiation. Since the pulse width of the picosecond laser is much shorter than the thermal relaxation time of the melanosome, the laser energy absorbed by the tissue can be better confined to the target, thereby effectively reducing thermal damage to surrounding tissues. If the laser pulse width is longer than the thermal relaxation time, the heat will spread to the adjacent tissues, causing collateral damage.

In short, the shorter the laser pulse width, the higher the energy focus, the stronger the peak power, the weaker the effect of light conversion into heat, and almost no photothermal effect, and it is not easy to spread to the surrounding intact tissue. In this way, the effect on the target tissue is stronger, and pigmented skin lesions can achieve better results in a shorter treatment cycle. It is not only fast, powerful, but also safer.

RESOLVE THE MATTERR

Skin problems that picosecond laser can solve

Picosecond laser has a wide range of indications, mainly including the following aspects:

Such as Ota's nevus, coffee spots, malar brown-blue nevus, freckles, age spots and various stubborn pigmented lesions can be improved by picosecond laser.

Picosecond laser can also achieve a good removal effect on eyebrow tattoos, eyeliner tattoos, lip tattoos and tattoos.

3、 Skin whitening and facial rejuvenation

Picosecond laser also has certain effects in whitening skin, improving skin quality and achieving facial rejuvenation.

However, picosecond laser is not omnipotent. Among the four aspects of "red, black, white and tender" that beauty lovers are concerned about, it is helpless against "red" (vascular problems), but it is very effective in "cracking down on pornography and cracking down on gangs".

Picosecond laser breaks the melanin particles in the bottom layer of the skin into powder, and then excretes it from the body through human metabolism. It is not a quick-acting "skin peeling" or "skin resurfacing" product. Because melanin is active, ultraviolet radiation, staying up late, long-term skin dehydration, and endocrine disorders may stimulate melanocytes to secrete a large number of melanin particles. Therefore, after the operation, you need to pay attention to strengthening sun protection, hydration, and adequate rest, so as to better control the production of melanin. Picosecond laser freckle removal is not addictive, but if the body is in an "imbalanced" state for a long time, and if you do not pay attention to sun protection, skin care and internal adjustment, the spots may reappear. The already formed spots cannot be adjusted and removed by themselves, and must be metabolized by external decomposition.

The explosive power of Picosecond laser to crush melanin is very strong. For example, if the ordinary laser freckle removal instrument needs 10 treatments to solve the problem, Picosecond laser only needs 2-3 times. In this way, the skin does not need to be repeatedly stimulated and repaired, so the skin will not become thinner.

Generally, there will be no redness or swelling after the picosecond treatment, and it will not affect normal work. After the treatment, you can hardly see the blush. However, some people with thin stratum corneum may experience slight redness, but it will gradually fade after 12 hours.

Some people may experience blackening after the picosecond treatment, but the blackening time is short, usually 3-7 days. This is because after the picosecond blasting of melanin, the pigment needs to be metabolized from the basal layer to the epidermis of the skin, and the blackening phenomenon actually indicates to a certain extent that the pigment in the basal layer is extracted more thoroughly. Pigmentation is secondary pigmentation after inflammation, which may be related to individual factors such as excessive sun exposure and dark skin color after treatment. This is a normal phenomenon. Try to avoid sun exposure after treatment, and you can also take oral vitamin C, tranexamic acid tablets, etc.

Whether there will be scabs after Picosecond depends on the type of spots. Some spots need to be blasted, in which case scabs will form, but the scabs formed after Picosecond treatment are very thin and basically invisible, and usually fall off naturally in about 3 days to a week.

If the spots have not been blasted, you can wipe your face normally the next morning; if the spots have been blasted, you need to wait until the scabs fall off before you can wipe your face normally. After Picosecond freckle removal, you cannot use hormone products to wipe your face, but you can use professional repair products in combination.

Picosecond laser will not leave scars on the skin. Picosecond laser with a specific wavelength can reach the diseased pigment tissue through the epidermis and dermis, and only act on the pigment particles, while the epidermis of the skin will not be damaged. In addition, the unique function of Picosecond Laser can selectively absorb various pigments in the skin (such as black, blue, green, brown, red, brown, etc.), so it will not leave scars on the skin.

The time it takes to see the effect after Picosecond Laser depends on whether the spot has been blasted. If the spot has been blasted, the effect can be seen after the scab falls off; if the spot has not been blasted, it will take a month to see the effect.

1. On the day of picosecond freckle removal, the treated area may experience slight redness, swelling, heat and pain, which is normal and you don't need to worry too much.

2. Some lesions will form scabs after surgery, which usually fall off by themselves after 7 to 10 days. During this period, be careful not to scrape the scabs with your fingers. You can use special beauty oil to soften the scabs and make them fall off naturally.

3. Do not wash your face within 24 hours after freckle removal surgery. After 24 hours, you can use professional medical-grade cleaning products to clean it.

4. After receiving laser freckle removal treatment, apply professional repair products to the treated area and do not use other drugs or cosmetics.

5. Sun protection is essential. The treated area is sensitive to sunlight. After surgery, you should apply professional physical sunscreen. It is recommended to use medical-grade sunscreen products. At the same time, try to avoid strong light exposure and do not sweat steam within 20 days.
