Dynamic Pulsed Light (DPL) is a hair removal method that utilizes laser power source to precisely target the roots of unwanted hairs. This technology has similarities with Intense Pulsed Light (IPL), but stands out in its more dynamic pulse which allows for better heat distribution and thus, more permanent results when compared to IPL treatments.
DPL works by targeting the hair follicle with light energy. The light energy is absorbed by the hair root, which then heats up and destroys the hair follicle. Over time, this can result in permanent hair removal.
Unlike traditional laser treatments, DPL can only target dark, coarse hairs. This is because the light energy needs to be absorbed by the hair to reach the hair follicle. DPL is also not suitable for all skin tones, as the light energy can also be absorbed by the skin.
The 530-750nm wavelength is in the absorption peak of hemoglobin (including two absorption peaks at 542 and 577nm), so it is more accurate and efficient in the treatment of superficial vascular lesions. At the same time, this band can promote the release of cytokines from vascular endothelial cells, and cytokines can stimulate Fibroblasts that produce more collagen, so they have a better skin rejuvenation effect;
The 640-750nm is in a special wavelength where melanin is highly absorbed and hemoglobin absorption is rapidly reduced, so it is more accurate and efficient to treat pigmented lesions (freckles, sun spots, and age spots). According to the selective photothermal action of pulsed light, it acts on the hair follicle, increases the temperature of the hair follicle, destroys the growth cells of the hair follicle, and achieves the effect of permanent hair removal without damaging the epidermis.
