Picosecond laser, why has it been burning for so long?
September 12, 2021

As a beautiful skin artifact that can remove freckles and rejuvenate the skin, picosecond laser has attracted many beauty-loving women. In this way, there is more hope to get rid of difficult melasma, freckles, age spots and hyperpigmentation, and also to rejuvenate the skin and say goodbye to the image of “yellow-faced woman”. This also makes many beauty salons and clinics do this project more and more people.

Although picosecond laser is indeed a popular item now, and it can also solve some skin problems, you must choose a regular medical beauty clinic or a professional and experienced doctor. Using a good picosecond laser can make your use more effective. Okay

The working principle of picosecond laser machine

The effect of laser on skin tissue is the basis of its treatment, including biological stimulation, photochemical reaction, photothermal effect, etc. Existing studies have found that when the pulse width reaches the picosecond level, it mainly manifests as a photomechanical effect rather than a simple photothermal effect.

The opto-mechanical effect produced by picosecond laser is that when the target chromophore absorbs laser energy, if the energy density exceeds a certain threshold, a plasma effect will be generated, and the instantaneous pressure wave will cause the target tissue to be blasted and smashed, forming cavitation. and bubbles.

Therefore, some researchers believe that compared with the Q-switched laser, the picosecond laser, which is mainly based on the photomechanical effect, can decompose the target tissue into smaller particles, which is more conducive to the phagocytosis and clearance of macrophages. In addition, the picosecond laser disintegrates the target chromophore through a lower energy density, and its pulse width is much lower than the thermal relaxation time of the melanosome, so it can further limit the thermal damage to the surrounding tissue, reduce the number of treatments, and reduce adverse reactions reaction.

q switched nd yag laser, as a milestone technological innovation in the field of laser beauty, has obvious advantages in many aspects of skin beauty. “Picosecond” is one trillionth of a second, and “picosecond laser” refers to a laser with a picosecond pulse width. Compared with the traditional laser with nanosecond pulse width, it directly shatters melanin with fast and powerful ability to improve pigmented skin problems.

In addition, picosecond laser can lighten spots on the basis of as little damage to the surrounding skin as possible, and produce better skin rejuvenation effect due to the stimulation of collagen. To put it simply, picosecond laser can act on the pigmentation of the epidermis and dermis, and has a relatively obvious effect on removing freckles, age spots, café-au-lait spots, cyan spots, Ota nevus, and even tattoos.

Picosecond laser freckle removal is a kind of laser technology, that is, the pulse duration (pulse width) emitted by each laser reaches the picosecond level, so that the skin tissue can stimulate the fibroblast response extensively and intensively under the high energy concentration. Generate collagen fibers and elastic fibers. The effect of picosecond freckle removal usually lasts about 1 to 2 years.

Picosecond laser portable does not have a good therapeutic effect on all stains, and some stains require multiple treatments to achieve satisfactory results. Excessive myth is that this technology is not scientific. More importantly, in order to avoid the occurrence of more serious pigmentation or the stimulation of chloasma, picosecond laser treatment must be performed in a regular medical institution, not in an unqualified studio or beauty salon.

There is mild pain during the treatment, the operation time is 20-30 minutes, the treatment cycle is 3-6 times a course of treatment, and the interval between each time is 1 month. The effect lasts for 1-2 years, and the recovery time is 1-3 days.

Applicable people who use picotech laser:

Those with various pigmentation spots on the face, such as freckles, age spots, café-au-lait spots, brown-cyan spots, nevus of Ota, etc.

What should I pay attention to before using picosure laser 1064nm/532nm?

1. Conduct doctor-patient communication, understand the complete surgical procedure and risks, and be mentally prepared.

2. Avoid exposure to the sun for two weeks before treatment, otherwise pigmentation and scarring may easily occur.

3. Do a good job of facial cleansing before treatment, and do not make up on the day.

4. There should be no inflammation or broken wounds on the face.

5. Do not take aspirin within two weeks before the operation, because these drugs will reduce the function of platelet coagulation.

6. Complete physical examination, cardiopulmonary, blood and other routine examinations to confirm that there is no serious systemic disease.

7. Women should avoid menstrual periods to avoid aggravating bruising and swelling; women who are pregnant and breastfeeding need to inform their doctor in advance.

8. Changes in bad living habits, such as prohibiting smoking and drinking before surgery.

9. Eat a light diet before surgery and avoid eating spicy, irritating and greasy foods.

It is precisely because the picosecond laser has such a good cosmetic effect, so many people choose to do this project. Also because picosecond lasers are more expensive than general beauty equipment, many good clinics and beauty salons still like to use them because patients prefer beauty machines with better effects.
