Picosecond is a laser cosmetic program that is notorious for being a "high-priced item".
In the end, how to get rid of the spots? Why does everyone recommend picoseconds?
In fact, the principle of all laser devices to remove the spots is the same.
Skin with freckles is not the same as the surrounding skin with normal skin color.
For these colored skin tissues, they directly absorb different wavelengths of laser light, which produces a "photothermal effect".
This allows us to break down the melanin and shatter the spots with the laser in order to lighten them.
The fairy who has the trouble of spotting, must have known a device, called "Q laser". This is a more basic and traditional way to get rid of spots.
What is the difference between a Q-tuned laser and a picosecond?
On the surface, the biggest difference between the two is "price".
Typically, picoseconds are several times more expensive than regular Q-tuned lasers.
Two of the biggest differences between regular lasers and picosecond lasers are the pulse energy, and the pulse width.
The picosecond is itself a unit of time
1,000 picoseconds = 1 nanosecond
As we can see, picoseconds are a much smaller unit than nanoseconds, and conversely, picoseconds are much faster than nanoseconds.
And nanoseconds are what we call the pulse width of a normal spot removal laser.
Therefore, the pulse width of a picosecond spot removal laser is much shorter than that of a normal spot removal laser.
What are the benefits of a shorter pulse width and a faster instantaneous release of laser light?
I know you will be confused, let's make an analogy
If melanin is a group of enemies
Picoseconds are like a gun
Ordinary lasers are like bows and arrows
Q-tuning is like a crossbow.
Hitting an enemy with a gun is more accurate, whereas hitting with a bow and arrow and crossbow leaves open the possibility that the enemy can parry a defense. Looking at it this way, which weapon would you prefer when going into battle?
Summary
The picosecond laser, compared to the original traditional skin laser spot removal
improves the effectiveness of the treatment of spot removal
also reduces the side effects of anti-blackness
(note that only reduced, that is, less likely to be anti-blackness, rather than completely eliminating the possibility of anti-blackness).
At the same time, for some common spot removal laser can not remove the pigment
such as blue-green tattoos and so on;
There are also common laser to remove the effect of the spots
such as chloasma
picoseconds can be done with good results.
This is a very hard dry goods, sisters may want to absorb, have questions sisters welcome to come to auntie Oh ~
I'm @ Dr. He Zhi beauty class, I come to answer your questions.
Picosecond laser is a kind of laser cosmetology, the so-called picosecond, refers to the time scale. That is, the duration of each pulse emitted by the laser is capable of being precise to the level of picoseconds.
Despite the shorter duration, the laser energy is intensified. It will precisely break up melanin particles on the skin at a faster rate and with greater energy, thus addressing a variety of blemishes caused by melanin deposits. Including: freckles, chloasma.
In addition, the honeycomb lens technology used in picosecond laser is able to focus each beam of laser light to stimulate the skin fibroblasts extensively and intensively, destroying the existing collagen and elastic fiber tissues, which makes the skin turn on the self-repairing process and produce more collagen and fibrous proteins. As a result, the skin will be more tender and tighter. Fine lines caused by broken skin tissue will also be enhanced.
Overall, picosecond lasers are more versatile, making them ideal for overall cosmetic enhancement.
Who is the picosecond laser for?People with tattoos: the picosecond laser is able to clean tattoos.
People with facial redness: the picosecond laser is able to synchronize the contraction of facial capillaries.
Facial fine lines, fine lines around the eyes, facial skin aging: this is mainly achieved by stimulating facial collagen, fibrin regeneration.
People with various color spots on the face: picosecond laser can be a good solution for freckles, age spots, coffee spots, brown spots, nevus of Ota and so on.
What are the advantages and disadvantages of picosecond lasers compared to other medical aesthetic programs?Picosecond laser has more prominent advantages:
Firstly, the more advanced equipment makes it able to find the color spots more accurately and smash them. Secondly, the picosecond laser has a short duration of action, causing little thermal damage to the skin, a shorter recovery period, and is very quick to operate.
Furthermore, compared with various injection-based cosmetic means, there is no open wound and true layer damage after picosecond laser treatment, so the damage to the skin is greatly reduced. Most importantly, picosecond lasers can be used for a variety of purposes, such as removing spots and rejuvenating the skin, removing fine lines, and removing tattoo pigment, which is very widely used.
But picosecond lasers also have their own limitations. Because of its advanced technology, the cost of picosecond lasers is relatively very high. In addition, this instrument has been on the market for a relatively short period of time, and its long-term safety and effectiveness, especially for refractory melasma, is still to be tested by time.
Ultra-picosecond breaks down the subcutaneous melanin by laser and then metabolizes it smoothly out of the body. Maybe at this time you will say, no matter it is tuned Q laser, picosecond laser or ultra picosecond laser, the principle is not so? But don't ignore a detail, 3 kinds of lasers for melanin crushing degree is different. Let's make an analogy, melanin is like a piece of cooked beef, Q laser treatment to achieve the same effect as beef jerky, picosecond can achieve beef grain, ultra-picosecond can reach the level of meat floss. So which one is better to be metabolized, it's clear, right?
Picosecond laser spot removal is a kind of laser technology, that is, each laser emits pulse duration (pulse width) to the level of picoseconds of laser light, so that the skin tissue in a high degree of energy concentration, extensive, intensive stimulation of fibroblast reaction, the generation of collagen fibers and elastin fibers, so as to improve the skin texture of the whole face, repair scars, lighten the wrinkles. Complications such as pain, discomfort, skin damage, erythema, infection, pigmentation abnormalities, scar formation, etc. may occur during treatment, so it is recommended that patients go to a regular medical institution for consultation and treatment.

Contraindications
He is directly shattering the skin melanin, and then through the skin lymphatic drainage out of the body to improve the pigmented skin. At the same time, the picosecond laser can initiate skin repair on its own to promote collagen renewal and proliferation, ultimately achieving a quadruple efficacy combination of removing pigment, whitening and rejuvenating the skin, improving fine lines, and enhancing the delicate skin texture.
What does picosecond mean?Picosecond laser is a technology that uses laser light in picoseconds (1 picosecond is equal to one trillionth of a second) to break up melanin particles. Picoseconds will not harm the skin around the pigmentation and the effect of picoseconds in removing pigmentation is by far the most outstanding laser technology.
Types of picoseconds:There are many brands of picosecond lasers on the market now, including Picosure, Enlighten, Picoway, Pico four and Discovery PICO, but the only one that has been certified by the US FDA and the Chinese CFDA is the global laser industry giant - Sanoso. The Picosure, produced by Sanosu, in order to avoid the damage caused by some irregular picosecond instruments on the skin as well as post-operative complications, the beauty of the fairies before doing picoseconds is best recognized Sanosu picosecond instruments.
What is the role of picosecondsSkin rejuvenation
Picoseconds mechanical light laser utilizes a very short pulse output, using shock waves to crush melanin particles into extremely fine particles, minimizing the side effects of photothermal effects, and solving the problem of skin pigmentation so as to achieve the purpose of rejuvenating the skin.
Removal of pigmentation
In addition to the pigmentation symptoms of the laser indeed have significant improvement, but also without harming the epidermis, start the skin's comprehensive renewal mechanism, so that the skin revitalization, to achieve the purpose of rejuvenation of the skin.
Tattoo removal
Picosecond laser can remove tattoos as well as other lasers, and can shorten the original traditional laser 10 treatments to remove tattoos frequency to 2-3 times.
Pore Shrinkage
After a picosecond laser, as the body needs to repair the hair follicles, it produces a lot of new collagen, and the new collagen helps the skin shrink pores, lighten fine lines, and lighten some of the less obvious scars.
Advantages of picoseconds
Less damage to the skin
The shorter the action time of the laser, the less the laser energy absorbed and accumulated in the target tissue spreads to the surrounding tissues, and the energy is maximally confined to the target target that needs to be treated, which protects the surrounding normal tissues, and thus the treatment is less damaging in general.
Precise crushing of melanin
The pulse width of the picosecond laser is only one percent of the traditional nanosecond laser, and the light energy produces almost no photothermal effect, while the volume of the target target absorbed by the target undergoes an extremely rapid expansion, so that the pigmented skin can produce stronger therapeutic effects in a shorter number of treatments.
Quick scabbing without back black
If the pigment particles are compared to rocks, the traditional laser can break the rocks into pebble size, while the picosecond laser can break them into dust state, which greatly reduces the chances of post-treatment hyperpigmentation.
Short recovery period from injury
Post-operative redness and swelling basically subside within 12-24 hours, with a wide range of applicability, one treatment can improve many facial problems at the same time. Nearly zero damage, there is no postoperative scabs to remove scabs quickly, suitable for people with a fast pace of life. Secondly, it does not have any scarring, color deposition, and anti-tanning problems.
Picosecond requires multiple treatments to achieve the effect
Picosecond laser removes pigmentation and tattoos generally need to be treated about 3~4 times, this is because the pigment exists in the level and exists at different times, when it will affect the effect of the treatment, it generally needs 3-4 times to completely remove clean.
What kind of people are suitable to do picosecond1. People who have a good economic foundation and need to remove chloasma, coffee spot, freckle, nevus of Ota are suitable to do picosecond.
2. People who have rich material foundation and want to remove facial acne scars are suitable for Picosecond.
3. People who want to get rid of spots and want to rejuvenate their skin.
Picosecond aftercare points1, after the treatment, use a cold mask or ice pack for 30 minutes to reduce the discomfort caused by the inflammatory response.
2, drink more water, use medical sterile mask to help skin moisturizing.
3, wash your face to clean it gently, never rub, and choose skin care products that do not contain additives and other possible irritants.
4, morning and evening a cell source of nutrition (micro-US shield) water light beauty treasure, to ensure that the metabolic needs of the skin after surgery. 4, good sunscreen to avoid postoperative hyperpigmentation produced.
5, not to take collagen, to prevent the body from too much aggregation caused by the accumulation of pits and so on.
