Picosecond or laser freckle removal effect is better. For those who pay attention to their beauty, they will pay great attention to their skin condition. They all want to look old and stay beautiful, which can give them great confidence. Is it better to share picosecond freckle or laser freckle?

Is it better to remove freckles in picoseconds or by laser 1 1: the principle of laser freckle and picosecond freckle.

Different skin types have different choices for laser freckle and picosecond freckle.

Laser freckle requires a lot of energy, generally above 500GY. Picosecond freckle removal only needs about 10GY.

Laser freckle removal is to decompose colored substances (such as black, brown and brown) on the skin surface into colorless or dim colors. Picosecond freckle removal is a substance that directly reduces the color on the skin surface.

Laser can be used in other parts, such as eyes (removing bags under eyes and wrinkles around eyes) and hair (removing hair), while skin in other parts can only be used to remove birthmarks and freckles.

2. Advantages and disadvantages of laser freckle and picosecond freckle.

Recently, many people are asking which is better, laser freckle or picosecond freckle? In fact, both methods have their own advantages and disadvantages.

Laser freckle removal is effective, but it requires patients to endure certain pain, and the effect is not immediate. Picosecond freckle is more expensive, but the effect is also obvious and almost painless.

So, if you can't stand some pain, then picosecond freckle removal is your best choice. If you can endure some stinging, the laser freckle removal effect will be better.

3. The price of laser freckle and picosecond freckle.

Skin freckle and laser freckle are two common skin whitening methods. They all have their own advantages and disadvantages, so if you are considering choosing between them, you should understand their differences.

First, let's take a look at skin freckle. This is a method of using high-energy light to "peel off" the color on the skin surface patch. It can obviously reduce melanin in the skin, so it can help eliminate dark spots, freckles and other unwanted dull skin. In contrast, laser speckle removal uses low-energy light to "absorb" excess color in the skin, so it can only be effective for some plaques.

Secondly, there are some differences in use. Freckle removal usually takes 3-5 hours, while laser freckle removal only takes about half an hour. In addition, some irritating smells will be produced in the process of skin freckle, but laser freckle does not have this problem.

In terms of cost, relatively speaking, skin freckle is much more expensive. Depending on the specific method used and the local conditions, one hour of skin color may cost 1000-2000 RMB. Relatively speaking, qualified doctors use low-energy beams to do laser freckle surgery, and the asking price is 300-700 yuan RMB.

In short, how to choose a method to remove freckles from skin depends on your personal situation.

Is picosecond freckle good or laser freckle good? Choose picosecond laser or ordinary laser treatment?

In fact, the principle of laser freckle removal is similar: it is to "crush" the pigment clumps in the skin through the selective photothermal effect of laser, so that the pigment clumps become tiny pigment particles, and then they are discharged through the body's metabolism, so that the spots will become lighter and lighter, and the effect of "disappearing" can be achieved by doing it several times more.

From the principle of freckle removal alone, picosecond laser is similar to other lasers, except that the pulse width of picosecond laser is shorter, reaching the picosecond level, so it can produce the photo-mechanical effect, while other lasers only have the nanosecond level (1 sec = 1 100 million nanoseconds = 1 100 million picoseconds). The shorter the pulse width, it means that the laser energy can be released in a shorter time and the pigment can be crushed more thoroughly. At the same time, the less damage to the surrounding normal tissues, the less likely it is to have side effects such as scabbing and pigmentation.

Is picosecond laser worth it?

First of all, the effect of laser speckle removal is not only related to the pulse width, but also related to the wavelength of laser. Pigment blocks with different colors can absorb lasers with different wavelengths, that is to say, lasers with different wavelengths are only better for pigments with certain colors. Some picosecond lasers have three wavelengths: 532nm, 755nm and 1064nm, but currently only 755nm is commonly used in China.

755 nm is the most widely absorbed wavelength of melanin. If your pigmentation is mainly dark brown, picoseconds is effective for you, but if your pigmentation is mainly red acne marks and red bloodshot, the effect is relatively low. It's better to do more photons.

No matter how powerful the instrument is, a good doctor is also very important.

No matter what kind of laser is used, doctors need to consider energy and level in many aspects. He needs to judge whether your spot is epidermal or dermal, what is your skin barrier, whether it is better to use only laser or cooperate with oral drugs, and so on. These are the keys to the therapeutic effect. When it comes to laser, people often have a doubt: will laser freckle be anti-black?

1, what is laser freckle prevention?

Laser freckle removal and anti-blackening are called "post-inflammatory pigmentation" in medicine. When the skin is treated by laser, the skin will be thermally damaged by laser, which will lead to inflammatory symptoms. Pigment reaction will occur after skin inflammation, and pigment precipitation will occur, which will make the spots diluted by laser turn black or dark brown again.

2. Why is the skin blackened?

Race and personal skin are important factors. The melanocyte activity of Asian yellow people is stronger than that of white people, so the melanogenesis and proliferation caused by postoperative inflammation are more likely to occur (research also shows that the anti-melanosis rate of yellow people after laser surgery is about 65,438+00%), which is also related to the physique of beauty seekers, including the hormone effect that makes melanogenesis active.

In addition, the reasons for anti-blackening include improper energy setting when the doctor operates the laser speckle remover, or the laser speckle remover used is not suitable for the patient's skin, or affected by the patient's medication, or the patient did not do a good job of sun protection after laser speckle removal, and ate too much food such as lemon or spice after surgery.

3. Will the skin metabolize pigment after laser freckle and anti-blackening?

The anti-blackening phenomenon of laser freckle is not the performance of freckle failure, but the performance of skin self-repair, which will be restored. After a period of time, the skin will metabolize these pigments and become normal skin color.

First of all, let's understand the difference between laser rejuvenation and laser. Laser rejuvenation is also called intense pulsed light. The intense pulsed light generated by laser rejuvenation can produce photochemical effect after acting on the skin, restore the original elasticity, stimulate fibroblast precursor cells to secrete more collagen, smooth fine wrinkles and enhance skin firmness. Let's talk about lasers. In fact, there are many kinds of lasers, such as Q-switched lasers, carbon dioxide lasers, erbium lasers and so on.

The current freckle laser is Q-switch laser, also called Q-switch, which uses the principle of light-induced explosion to achieve the effect of freckle and tattoo washing. In fact, it is the same as laser rejuvenation. Q-switched laser is just a general term, but any device that can emit this light is called Q-switched laser. The price of equipment ranges from thousands to millions. Of course, don't blindly compare prices.

Be sure to ask what equipment is used in the project first, such as E-Man, Felton, fotona, c6/c8 of Sino Show, and ruby ruby of Germany, including picoseconds and picoseconds of honeycombs, which we often say. These are top-class Q-switch devices, and these devices are relatively guaranteed in terms of therapeutic effect and safety. Don't let anyone cheat.

Laser skin rejuvenation belongs to a broad spectrum, which can gather different colors of light together and can target melanin, red blood, acne, acne and so on. Therefore, laser rejuvenation is very comprehensive and can take care of all aspects. But laser rejuvenation is not focused enough, just like we are human beings, it is impossible to do everything.

Q-switched laser is a very thin beam, which can directly hit our melanin through different wavelengths, so it is very, very targeted. We can compare laser rejuvenation to a flashlight, which can illuminate the surrounding environment within a certain range, but it won't play much role if it is too far away. Q-switched lasers can be compared to laser pens. Although it can't illuminate the surrounding environment, it can illuminate the target far away very accurately.

How to choose laser rejuvenation and picosecond?

Such as freckle, sunburn and seborrheic keratosis. Laser rejuvenation is generally recommended for these less serious epidermal spots. If it is serious, it is recommended to use Q-switched laser, such as Ota nevus and brown-blue nevus. Q-switched laser is generally recommended for these dermal spots, and mixed spots with complex etiology such as chloasma are generally selected for Q-switched laser or combined treatment.

Finally, let me remind you that medical beauty is not absolute. For example, the same spot grows on different people's faces, but the size and depth of the spot are different, and the way to choose treatment may be different, so the specific situation must listen to the opinions of professional doctors.
