Pulsed dye laser (PDL) beauty is an advanced laser beauty technology that has significant effects in skin beauty and skin disease treatment. Its unique technical features have attracted much attention in the beauty market.


  1. Subdivision types of PDL laser

Pulsed dye laser (PDL) is a type of laser with a specific wavelength. Its main types include:

(1)Dye laser: uses organic dyes as the laser medium to produce light of specific wavelengths;

(2)Pulse laser: By adjusting parameters such as pulse width and energy, precise treatment can be achieved.

  1. Wavelength of PDL laser

Common wavelengths for pulsed dye lasers (PDL) are 585nm and 595nm. These two wavelengths of laser light can be absorbed by hemoglobin in the skin to achieve therapeutic purposes.

  1. The function of PDL laser

PDL laser is widely used in the field of beauty, and its main functions are as follows:

(1)Treatment of facial vascular diseases: PDL laser can targetedly destroy vascular lesions, such as hemangiomas, port wine stains, etc.;

(2)Acne treatment: reduce inflammation and improve acne symptoms by destroying Propionibacterium acnes;

(3)Treatment of pigmented diseases: PDL laser can treat pigmentation, sun spots and other problems;

(4)Skin rejuvenation: stimulate the proliferation of skin collagen and elastic fibers, and improve problems such as skin sagging and fine lines;

(5)Hair removal: Permanent hair removal is achieved by destroying hair follicles;

(6)Skin rejuvenation: Promote skin metabolism, improve skin texture and skin color.


PDL beauty instruments have achieved remarkable results in the field of skin beauty with their unique wavelengths and therapeutic effects. With the continuous development of laser technology, PDL beauty instruments will be more widely used in the beauty industry.
