Spots on the face are not good-looking, what are the advantages of picosecond laser, it can effectively improve the spots.

 

Picosecond laser introduction

Picosecond laser directly smashes melanin with a fast and powerful energy, and excretes it through skin lymph to improve pigmented skin. At the same time, it starts skin repair by itself, promotes the renewal and proliferation of collagen, and achieves the effects of removing pigment, whitening and rejuvenating the skin, improving fine lines, and refining the skin texture.

Picosecond laser means that the pulse width reaches the level of picosecond (1 picosecond is equivalent to 1/1000 nanosecond), and the duration of the pulse emitted by it is very short. Its energy is output in the form of short pulses, based on selective photothermolysis, which is highly selective to the target without obvious damage to the surrounding normal tissues, so as to achieve the ideal skin beautification effect of non-invasive treatment.

Advantages of picoseconds

1. Shorter course of treatment: Compared with ordinary laser, picosecond laser treatment is more effective in a single treatment, and the treatment process can be shortened from 10 times of traditional laser treatment to 2-3 times.

2. More efficient: Unlike the past, different problems require different laser treatments, and one treatment can improve multiple problems on the face at the same time.

3. Low Anti-Blackness Rate: It has a superior therapeutic effect on stubborn tattoos and effectively reduces the anti-blackness rate.

4. Reduce pigmentation: the blasting ability is stronger, the blasting is finer, the tissue absorption is better, and the curative effect is also better. At the same time, picosecond laser heat damage is small, and the probability of immediate pigmentation is also greatly reduced.

Picosecond can improve skin texture, whiten skin and eliminate fine wrinkles. In foreign clinical trials, the risk is almost zero. Freckle removal no longer requires frequent treatments like traditional lasers and the risk of anti-blackness is feared.

What does picosecond do?

Take the pigment treatment commonly seen in laser treatment as an example. The basic principle of picosecond laser treatment is to use the receiving selectivity of the laser to directly bombard the pigment block on the basis of not harming the skin tissue as much as possible, and use the photomechanical reaction of the photothermal reaction to crush it, and the crushed pigment block will be destroyed. Elimination of macrophage parcels in vivo.

Moreover, the difference between picosecond laser and traditional laser therapy (Q-regulated nanosecond laser) is: the speed of picosecond laser is extremely fast, and the energy required to achieve the therapeutic effect is less, and the target has not had time to produce too much photothermal reaction. It is "crushed" by the photomechanical reaction, causing damage to surrounding tissues. The target is "shattered" by the photomechanical reaction before it can produce too much photothermal reaction to damage the surrounding tissues. Therefore, picosecond laser: faster, more powerful, less painful, shorter treatment cycle.

After the operation, good nursing work is conducive to the faster recovery of patients. The more meticulous the nursing work, the better. The specific nursing methods are as follows.

1. Try to avoid sun exposure three weeks before receiving laser freckle treatment, so as not to affect the treatment effect. Eat less greasy and spicy food and keep a good mood. Women avoid menstrual periods.

2. After the laser treatment, the skin will be red, swollen and slightly bleeding due to the energy irradiation. It will gradually heal and produce scabs in about a day. The scabs will fall off naturally in about 3 to 5 days and turn pink. During this process, pay attention to keeping it clean and avoid exposure to the sun, otherwise the skin will turn dark instead
