What is superpicosecond?

Whether picosecond or superpicosecond, it is a unit of time. Picosecond and superpicosecond are the same. They actually apply laser to specific parts of the face, gather energy and emit it to the skin, using the energy to crush melanin to achieve the purpose of improving skin color and removing freckles. Both have the effects of whitening, lightening spots, tightening skin, removing acne marks, and smoothing acne pits. Ultra-picosecond has three wavelengths: 1064nm/532nm/785nm. It uses photoacoustic effect to attack the depth of melanin more accurately and comprehensively, and can reach a depth of 3-4mm under the skin. The superpicosecond pulse width is between 1ps and 400ps, with large energy focus, stronger effect on pigments, and less damage to the skin.

2. Tattoos, eyebrow tattoos, tattoos Eyeliner, etc.;

3. Dark yellow, rough and dull skin, dark circles under the eyes, lip pigmentation, etc.;

Can ultra-picosecond laser treatment be performed in one go?

Super picosecond laser treatment can not only remove skin problems such as spots and freckles, but also remove acne marks and brighten skin tone. However, although ultra-picosecond technology is effective, it cannot solve all problems at once. For different skin problems, the number of ultra-picosecond treatments is also different. For example, chloasma, because chloasma is relatively stubborn, the number of ultra-picosecond laser treatments must be comprehensively analyzed based on the patient's own skin condition!

What should you pay attention to after superpicosecond laser treatment?

1. Prevent inflammation after treatment: The main manifestations are redness, swelling, heat and pain in the treated area, which usually disappear on their own after treatment. In order to reduce the discomfort caused by the inflammatory reaction, a cold compress mask or ice pack is generally used immediately after treatment for 30 minutes to reduce inflammation and promote skin repair. Apply ice and repair after treatment to help the redness and heat subside. By replenishing moisture to the skin, it helps speed up skin metabolism. Therefore, after super picosecond treatment, in addition to daily application on the face to replenish water, locking in moisture is also an indispensable protective measure.

2. Moisturizing: Skin metabolism will accelerate after laser treatment and requires more water, so you should drink more water to maintain humidity. In addition, it is also important to use medical sterile masks. This type of mask helps repair the skin barrier and function.

3. Cleaning: Wash your face gently and do not rub it. When choosing skin cleansing products, it is recommended not to use conventional skin cleansing products. Try to choose medical skin care products that do not contain additives and other possible irritations under the advice of a doctor. It is strictly prohibited to use facial cleansers with functions such as oil removal, scrub, fruit acid, deep purification, etc.

4. Avoid irritating the skin: Try to use daily skin care products recommended by doctors after laser surgery. These products are less irritating and can better repair skin sensitivity after laser treatment.

5. Sun protection: In order to avoid postoperative pigmentation, sun protection must be done after surgery.
