20 Common Lasers for Treatments<\/h1><\/h1><\/div>

The application of laser in dermatology has a history of more than 30 years. Short-pulse laser and intense pulsed light (IPL) have been widely used in dermatology, which has made a large number of intractable skin diseases have a great therapeutic effect. A breakthrough that fulfills our dermatologist’s dream of non-invasive treatment of disease. In fact, there are many types of lasers used in dermatology. Below I will mainly introduce the commonly used dermatology laser therapy instruments and their applications in clinical practice.<\/p>\n<\/div>

The yellow light with a wavelength of 578 nm is located at the absorption peak of hemoglobin and can be absorbed better; while the green light with a wavelength of 510 nm is absorbed by hemoglobin and melanin. Clinically, it is mainly used for the treatment of vascular proliferative skin diseases, such as port-wine stains, telangiectasia, rosacea, spider nevus, etc. In addition, copper vapor laser can also be used as the light source of photodynamic therapy to treat port-wine stains, with good clinical effect.<\/p>\n<\/div>

8. Potassium Titanium Phosphate Laser (KTPJ Laser)<\/h3><\/h3><\/div>

The wavelength is 532nm, and the power is 1-20W. It is mainly used in the clinical treatment of vascular proliferative diseases, telangiectasia, rosacea (telangiectasia type), and small varicose veins. Postoperative hypopigmentation is more common, and it can also be used as a light source for photodynamic therapy to treat port-wine stains.<\/p>\n<\/div>

9. Alexandrite Laser<\/h3><\/h3><\/div>

10. Ruby Laser<\/h3><\/h3><\/div>

The wavelength is 694.3 nm, and the pulse width is 20-40 ns in Q-switched mode. Long pulse width mode is mainly used for hair removal.<\/p>\n<\/div>

11. Pulsed garnet (Nd: YAG) laser<\/h3><\/h3><\/div>

The wavelength is 1064nm, and the pulse width is 5-40s in the Q-switched mode. It is mainly used to treat various dermal hyperpigmented skin diseases, such as Ota nevus, acquired Ota nevus-like spots, tattoos, etc. There is basically no scar formation. The long pulse width mode is mainly used for the treatment of vascular proliferative skin diseases such as strawberry hemangioma, port wine stain, telangiectasia, etc. It can also be used for hair removal, wrinkle removal and skin tightening.<\/p>\n<\/div>
