Product Description *Picosecond laser machine principle The picosecond laser pulse width is only one percent of the traditional Q-switched nanosecond laser. Its Superior performance ensures that the picosecond laser breaks down the pigment particles more thoroughly and with less damage to the surrounding Tissue. The 755 honeycomb picosecond refers to the picosecond honeycomb laser, which uses a 755nm wavelength laser and a honeycomb Instant Lens to focus 70% of the laser energy. Each laser light provides 10% of the skin Tissue with high-efficiency shock wave, shattering the skin layer. The melanin also transmits the shock wave to the deep dermis, stimulates Collagen production, accelerates Metabolism, and achieves beauty purposes.
