The difference between picoseconds and laser spot removal

The difference between picoseconds and laser spot removal, in our life, about the beauty of the skin care aspects have always been everyone's concern, in order to have a better skin condition many people will take a variety of measures, the following to understand the difference between picoseconds and laser spot removal.

The difference between picoseconds and laser spot removal1

In fact, the so-called picoseconds spot removal refers to picosecond laser spot removal, which is a kind of treatment among laser spot removal, and there is no difference between the two kinds of treatment, but it is a kind of inclusive relationship. There are a lot of other ways to get rid of laser spots in the clinic, such as Q-tuned lasers or non-exfoliative fractional lasers, as well as exfoliative fractional lasers, copper bromide lasers, and pulsed dye lasers.

But in these laser spot treatment, it is generally recommended that patients apply Q laser or picosecond laser, picosecond laser is a new type of laser spot treatment in the clinic, and its safety is more worthy of affirmation, and the therapeutic effect is also good, the patients can apply picosecond laser in the clinic to remove the spots of the treatment.

Picosecond is a type of laser, it is just a newer version of laser, and the effect of spot removal is better when compared with the laser in the past. Because the pulse width of picoseconds is smaller compared to ordinary lasers, it outputs a stronger and more concentrated unit of energy, so it can break up the pigment into smaller pieces, resulting in better absorption of the pigment, so the effect of removing the spots is better.

In addition, because it produces less photothermal damage, so the incidence of adverse reactions will be lower. In short, the picosecond itself belongs to a kind of laser, only it is more powerful and the side effects will be less.

What is a picosecond laser?

"Picosecond" is a unit of time that is converted like this: 1 second = 1,000,000,000,000,000 picoseconds. A picosecond laser is the amount of time that light hitting the skin stays in the skin - picoseconds. In other words it removes marks from the face exceptionally fast.

Picosecond lasers are also by far the most effective laser technology for removing discoloration.

What are the advantages of the action of the picosecond laser?

1, melanin removal rate is higher

Picosecond laser can shatter melanin into extremely small particles, more convenient for the body to metabolize melanin, greatly improving the melanin removal rate.

2. Faster melanin removal

The honeycomb treatment speed of the picosecond laser is 90 times faster than that of the traditional Q-modulated laser, which instantly breaks up the pigmented particles and greatly shortens the treatment time.

3. Reject the risk of re-darkening

Based on the fast and powerful deterrent ability of the picosecond mechanical light laser, the chance of thermal damage to the skin is greatly reduced, and the risk of stimulating the melanin to be active again (re-darkening) is also relatively reduced.

4, remove spots at the same time to start the repair mechanism

Picosecond laser in the deterrence of melanin at the same time the shock wave will be transmitted to the deeper layers of the skin, to start the repair mechanism, to promote the renewal of collagen and proliferation, to achieve whitening and softening of the skin to remove the effect of fine lines.

5, does not harm the normal tissue

Perfectly remove the pigmentation at the same time, through the skin healing mechanism, the dermis under the location of the photographs produced new collagen and elastic fibers, simultaneous rejuvenation, skin tightening of the excellent results.

Precautions after picosecond laser

1, usually after the treatment of the skin will be a little red, with an ice pack ice 15 ~ 30 minutes on it!

2, just after receiving picosecond laser treatment, facial movements should be gentle, do not use irritating skin care products.

3, just after the spot treatment parts of the sun will be very sensitive to the sun, 3 months after the treatment should pay attention to sunscreen to avoid pigmentation.

4, within a week, face water ban, can only use cotton swabs dipped in water to wipe the area around the eyes carefully to avoid bacterial infection.

5, the affected area should be wiped every day medical repair products to accelerate skin repair.

6, picoseconds after the operation is recommended every morning and evening to apply a piece of hydration mask, accelerate the skin metabolism.

Principle of laser spot removal

The laser is a kind of high-intensity instantaneous energy of visible light, and the different wavelengths of laser light can improve the color of the skin, so a lot of people use the laser for the treatment of freckles, and a lot of laser treatments have good treatment means for pigmentation, laser treatment of pigmentation, and laser treatment of pigmentation. The treatment time of laser pigmentation is relatively short, the skin needs a metabolism function, generally to achieve the desired effect of four to six times of treatment, so laser treatment is a long-term and effective treatment of pigmentation process.

What is the principle of laser treatment? It mainly relies on the laser light emitted by the treatment instrument to penetrate the pigmented skin and enter the pigmented skin, and then the pigmented skin is treated by the strong laser light, which will be dissipated, so there is no damage to the normal skin.

The principle of laser freckle removal is that the laser light emitted by the treatment instrument can penetrate the lesion skin extremely smoothly, enter the lesion area, and treat the pigment of the lesion area. The freckle pigment will change under the powerful laser irradiation and then dissipate on its own, thus getting cured. The laser does not forcibly remove the pigment, but treats it through the skin. However, there will be scars after the treatment if it is not carefully taken care of, and because of its selectivity, i.e., it acts only on the pigment particles and does not damage the normal skin.

Freckles: small brown spots from the tip of a pin to a grain of rice, scattered on the cheeks and the bridge of the nose, usually present at an early age and always present.

Moles: mostly appear gradually after puberty, several to dozens, pinpoint to rice grain size brown or black flat spots or raised papules, mainly distributed in the face and neck.

Zygomatic nevus: Gradually appeared after puberty on both cheekbones or the lateral lower part of the eyes gray-blue pinhead to rice grain size of the cluster of spots, a few patients have a family genetic predisposition.

Liver spots: brown spots that gradually increase after the age of 25, mostly appear symmetrically on both cheeks. The color is similar to boiled pig liver, so it is called liver spot, which is not related to liver disease.

Otaemonitis: gray-blue mottled patches generally appear on the upper part of one side of the face, and even the sclera of the eyeballs will have gray-blue color, and the pigmentation is deep to the dermis.

Elderly spots: several to dozens of waxy, rough brown or pimples and plaques, and gradually increase in size, more sun exposure places such as the face and the back of the hands.

Sun spots: oval-shaped raised or smooth, dark brown plaques, easy to appear on the outside of the forearms, the back of the hands, the anterior side of the calves and face. It is about the size of a grain of rice to a nickel' and begins to appear in middle age.

Light café au lait spots: usually present at birth, irregularly shaped light brown patches.

Laser treatment of targeted comparison of pigmentation is very good treatment, the principle of laser treatment to dispel spots is also more obvious, the side effects are very small just easy to leave traces, but as long as you pay attention to the A, sunscreen and replenish the skin's moisture, it will not generally will not leave scars, for the skin it is generally no damage, within three months of the skin must be coated with sunscreen, the individual pigmentation will be deepened! But three to six months later will subside.
