There are many types of medical lasers, and different types of lasers have different effects.Different laser instruments can be selected according to the increase of different types of pigments.

Q-switched laser: divided into Q-switched 694nm ruby laser, Q-switched alexandrite laser, Q-switched 1064nm laser, Q-switched frequency-doubling 532nm laser.

After the pigment group absorbs energy in an instant, the temperature rises rapidly, causing the pigment or pigment-containing cells to rapidly expand and rupture, forming small fragments (blasting effect), which are excreted through body surface metabolism, macrophage phagocytosis, blood or lymph fluid.

Intense pulsed light: Pulsed light is a broad-spectrum light, 500-1200nm, formed by focusing and filtering a high-intensity light source. Different wavelengths can be selected according to the increase of different pigments.

Laser hair removal

Commonly used hair removal laser equipment are:

1. Ruby laser: 694nm

2. Intense pulsed light: 695nm/640nm

3. Alexandrite laser: 755nm

4.Nd: YAG laser: 1064nm

5. Semiconductor laser: 800/810nm

6. Ultrasonic hair removal

Facial Rejuvenation Laser

1. Intense Pulsed Light IPL (Photon Rejuvenation)

2. Fractional laser

3. Non-ablative fractional laser: Erbium glass laser (1550nm/1540nm), neodymium-doped yttrium aluminum garnet laser, Er: Fiber laser (1410 nm), ruby laser (694nm), thulium fiber laser

4. Exfoliating lattice laser: 2940nm Er: YAG laser, 2790nm yttrium gallium garnet laser, CO2 laser

Whether the laser efficacy is significant or not often depends on the accuracy of the operator's operation of the laser instrument and the correct judgment of the wavelength.
