Q-switched laser and picosecond laser, which one is better?

Compared with picosecond laser, Q-switched laser is better. Picosecond laser is a picosecond machine, which can crush the melanin under the skin through a specific laser beam, and then excrete it from the body with the metabolism of epidermal cells, thereby achieving the effect of fading facial spots and acne marks. Q-switched laser uses pulsed laser, which has a higher frequency than picosecond laser, so the cleaning effect will be more obvious.

1. Laser freckle removal method:

1.Q-switched laser freckle removal: 

Q-switched laser freckle removal uses laser heat energy of different wavelengths to act on the skin, selectively photothermally, and selectively destroys melanocytes in the skin, so as to achieve the effect of removing chloasma, with high safety, ideal effect, and make the skin smooth and beautiful.

2.Picosecond laser: 

Using 755 wavelength laser and honeycomb instant lens (Focus), 70% of laser energy is focused. Each laser light provides 10% of the skin tissue with a high-small shock wave effect, which shatters the melanocytes in the epidermis. At the same time, the shock wave is transmitted to the deep dermis, which starts to repair growth factors, promotes the renewal and proliferation of collagen and elastic fibers, accelerates the metabolism of the skin, and accelerates the metabolism and excretion of melanin from the body, thereby solving the deep pigmentation problem at the root.

2. Advantages of picosecond laser compared with traditional laser:

Pulse width, the shorter the pulse width, the weaker the effect of light conversion to heat, and almost no photothermal effect is produced. It is not easy to spread to the surrounding intact tissues, and the effect on the target tissue is stronger, which can make pigmented skin lesions produce stronger efficacy with shorter treatment times, faster speed, stronger energy, better effect, and safer effect.

3. Precautions after laser freckle removal:

1. After laser freckle removal, apply anti-inflammatory cream to the treated area every day. The wound will slowly scab and peel off in about a week, and it will be pink.

2. Everyone reacts differently after laser treatment. Some people may experience some degree of redness and swelling, which can be relieved by cold compresses.

3. Do not use fillers or other injections for two weeks before and after surgery.

4. After receiving laser treatment, facial movements should be gentle and not too large to avoid pulling the injured area.

5. Use fresh vegetables rich in vitamin C and protein-rich foods.

6. Pay attention to sun protection within three months after laser freckle treatment. This area will be very sensitive to sunlight and pigment deposition should be avoided.

In summary, compared with picosecond, Q-switched laser from SANHE Laser has a better picosecond effect and can be improved in a short time.
