How do you remove freckles? Why does everyone suggest doing picoseconds with me?
In fact, the principle of freckle removal by all laser instruments is the same.
Freckles appear on the skin, which is different from the surrounding normal skin.
For these colored skin tissues, they will directly absorb lasers with different wavelengths, thus producing a "photothermal effect".
In this way, we can decompose melanin and break spots by laser to achieve the effect of fading spots.
The spotted fairy must know an instrument called Q-switched laser. This is a relatively basic traditional laser freckle removing method.
What's the difference between Q-switched laser and picosecond?
On the surface, the biggest difference between them is "price".
Usually, the price of picoseconds is several times higher than that of ordinary Q-switched lasers.
The two biggest differences between ordinary laser and picosecond laser are pulse energy and pulse width.
Picosecond itself is a unit of time.
1 0,000 picoseconds = 1 nanosecond
We can see that the unit of picosecond is much less than nanosecond, on the contrary, the speed of picosecond is much higher than nanosecond.
Nanosecond is the pulse width of common freckle laser.
Therefore, the pulse width of picosecond speckle removal is much shorter than that of ordinary speckle removal laser.
Short pulse width and fast instantaneous laser speed. What are the benefits?
I know everyone must look puzzled when they say this. Let's make a metaphor.
If melanin is a group of enemies
Picosecond is like a gun.
Ordinary lasers are like bows and arrows.
Q-switched is like a crossbow.
It is more accurate to hit the enemy with a gun, but it is possible that the enemy can resist the defense by hitting with bow and crossbow. In this way, which weapon do you prefer to choose when you go to war?
abstract
Compared with traditional skin laser, picosecond laser can remove spots.
And the therapeutic effect of freckle removal is improved.
It also reduces the side effects of anti-black.
(Note, it's only reduced, that is, it's more difficult to fight against black gangs, rather than completely eliminating the possibility of anti-black gangs).
At the same time, for some pigments that ordinary freckle laser can't remove.
Such as blue-green tattoos and so on;
There is also a common laser to remove bad spots.
Such as chloasma
Picosecond can achieve good results.
This is a very hard dry goods, and sisters may have to absorb it well. Sisters with problems are welcome to come to aunt ~
I'm Dr. He Zhi from the beauty class, and I'll answer your question.
Picosecond laser is a kind of laser beauty. The so-called picosecond refers to the time scale. In other words, the pulse duration of each laser emission can be accurate to the picosecond level.
Although the time is short, the laser energy has been strengthened. It will accurately crush melanin particles on the skin with faster speed and greater energy, thus solving various spots caused by melanin deposition. Including freckles and chloasma.
In addition, picosecond laser uses honeycomb lens technology, which can focus each laser beam, stimulate skin fibroblasts extensively and intensively, destroy existing collagen and elastic fiber tissues, and make the skin start the self-repair process, producing more collagen and fibrin. This will make the skin whiter and firmer. Fine lines caused by skin tissue damage will also be strengthened.
Generally speaking, the effect of picosecond laser is relatively complete, which is very suitable for overall beauty improvement.
Which groups are picosecond lasers suitable for? Tattooist: Picosecond laser can wash tattoos.
People with red blood on their faces: Picosecond laser can contract facial capillaries synchronously.
Facial fine lines, fine lines around eyes and facial skin aging: this is mainly achieved by stimulating the regeneration of facial collagen and fibrin.
There are all kinds of spots on the face: picosecond laser can solve freckles, senile spots, coffee spots, brown-blue spots, OTA moles and so on.
What are the advantages and disadvantages of picosecond laser compared with other medical beauty projects? Picosecond lasers have outstanding advantages:
First of all, more advanced equipment makes it possible to find the stain more accurately and crush it. Secondly, picosecond laser has short action time, little thermal damage to skin, short recovery period and very fast operation.
Moreover, compared with various injection cosmetic methods, picosecond laser treatment has no pioneer wound and real layer damage, and the damage to the skin is greatly reduced. Most importantly, picosecond laser can kill many birds with one arrow, which can not only remove spots, purify and rejuvenate skin, but also remove fine lines and tattoo pigments, and is widely used.
But picosecond laser also has its own limitations. Due to the advanced technology, the cost of picosecond laser is relatively high. In addition, this instrument has been on the market for a short time, and its long-term safety and effect, especially the effect of refractory chloasma, need time to test.
In picoseconds, melanin under the skin is crushed by laser, then metabolized and excreted smoothly. Maybe at this time, you will say, whether it is Q-switched laser, picosecond laser or picosecond laser, isn't that the principle? But don't ignore a detail. The three lasers crush melanin to different degrees. For example, melanin is like a piece of cooked beef. After Q-switched laser treatment, the same effect as beef jerky can be achieved. Beef granules can be achieved in picoseconds, and the degree of meat looseness can be achieved in picoseconds. So which one is better for metabolism, is it clear at a glance?
Picosecond laser speckle removal is a kind of laser technology, that is, the pulse duration (pulse width) of each laser beam reaches picosecond level, which makes skin tissue stimulate fibroblast reaction extensively and strongly under high energy concentration to generate collagen fibers and elastic fibers, thus improving the skin quality of the whole face, repairing scars and fading wrinkles. Complications may occur during the treatment, such as pain, discomfort, skin damage, erythema, infection, abnormal pigment and scar formation. & gt

Taboo crowd
He directly smashes skin melanin and then excretes it through skin lymph to improve pigmented skin. At the same time, picosecond laser can automatically start skin repair, promote the renewal and proliferation of collagen, and finally achieve four therapeutic combinations of removing pigment, whitening and rejuvenating skin, improving fine lines and improving delicate skin.
What does picosecond mean? Picosecond laser is a technology that uses picosecond laser to crush melanin particles (1 picosecond is equal to one trillionth of a second). Picosecond laser will not harm the skin around the stain, and the effect of removing the stain by picosecond is also the most prominent laser technology so far.
Types of picoseconds: There are many picosecond laser brands on the market, including Picosure, Enlighten, Picoway, Pico four and Discovery PICO, but the only one that has been certified by FDA and CFDA of China is Picosure produced by Sino Show Company, a global laser industry giant. In order to avoid skin injury and postoperative complications caused by some nonstandard picosecond instruments, fairies who love beauty had better look for Sino Show picosecond instruments before making picoseconds.
What does picosecond do to rejuvenate the skin?
Picosecond mechanical light laser uses extremely short pulse output mode, and uses shock wave to crush melanin particles into very fine particles, thus minimizing the side effects of photothermal effect, solving skin pigmentation and achieving the purpose of skin rejuvenation.
Remove stains
Picosecond laser can not only significantly improve the symptoms of pigmentation, but also activate the whole skin renewal mechanism without damaging the epidermis, so as to reactivate the skin and achieve the purpose of rejuvenation.
Get a tattoo
Like other lasers, picosecond laser can remove tattoos, which can shorten the tattoo removal frequency of traditional laser 10 treatment to 2~3 times.
Shrink pores
After picosecond laser, because the body needs to repair hair follicles, it will produce a lot of new collagen, which can help the skin shrink pores, fade fine lines and fade some inconspicuous scars.
The advantage of picoseconds is that it is less harmful to the skin.
The shorter the action time of laser, the less likely it is that the laser energy absorbed and accumulated in the target tissue will spread to the surrounding tissues, and the energy will be confined to the target area that needs treatment to the greatest extent, thus protecting the surrounding normal tissues, so the overall damage of treatment is less.
Precisely crush melanin
The pulse width of picosecond laser is only 1% of that of traditional nanosecond laser, and the light energy hardly produces photothermal effect, but it expands rapidly after being absorbed by the target, which makes pigmented skin have stronger curative effect in a shorter treatment time.
Will scabbing turn black soon?
If pigment particles are compared to rocks, traditional laser can grind rocks into pebbles, while picosecond laser can grind them into dust, so the probability of pigmentation after treatment is greatly reduced.
Short recovery period from injury
Postoperative redness and swelling can basically disappear within 12-24 hours, and the application range is wide. One treatment can improve all kinds of facial problems at the same time. Almost zero injury, no scab after operation, quick scab removal, suitable for people with fast pace of life. Secondly, it won't have any scars, dark colors and anti-black problems.
Picosecond needs multiple treatments to achieve the effect. Picosecond laser to remove stains and tattoos generally requires about 3-4 treatments. This is because different pigment content and different time will affect the therapeutic effect, and it usually takes 3-4 times to completely remove it.
Picosecond 1 for whom? People who have a good economic foundation and need to get rid of chloasma, coffee spots, freckles and OTA moles are suitable for picoseconds.
2. The material base is relatively rich, and people who want to remove facial acne scars are suitable for picoseconds.
3. People who want to freckle and rejuvenate their skin.
Nursing points after picosecond freckle removal 1. After treatment, apply a cold mask or ice pack for 30 minutes to relieve the discomfort caused by inflammatory reaction.
2. Drink plenty of water and use a medical sterile mask to help moisturize the skin.
3. Wash your face gently, don't rub it, and choose skin care products that may cause irritation without additives.
4. Cell-derived nutrition (Vimeton) should be used once in the morning and once in the evening to ensure the metabolic needs of the skin after operation. 4. Do a good job of sun protection to avoid postoperative pigmentation.
5. Don't take collagen to prevent excessive accumulation and pits in the body.
