It uses a delicate spectrum of 640 - 750nm for the treatment of hair removal, acting on the hair follicles based on the selective photothermal effect of pulsed light. It increases the temperature of the hair follicle and destroys the growth cells of the hair follicle, and the ratio of melanin absorption rate and penetration depth is guaranteed at the same time. The epidermis is lowered in advance to achieve the effect of hair removal.
Its another 530nm - 750nm narrow-spectrum light can simultaneously generate photothermal photochemical effects, rearrange collagen fibers and elastic fibers in the deep part, and restore skin elasticity, at the same time enhance the function of the vascular, improve circulation, and make skin smooth, delicate and flexible. The energy density of DPL is much higher than other conventional IPL. Its higher density is very useful to treat epidermal acne and pigmentation.
