Nantong plastic surgery experts said that Feidun Da Q has the following three technical advantages: First, high-energy treatment. Feidun large Q skin pigment laser adopts double YAG laser crystals in series technology, that is, one is used as emitter and the other as amplifier. The maximum fundamental frequency laser energy of two poles in series can reach 2000mJ/ pulse, which effectively ensures that all four wavelengths have enough energy for chloasma treatment. Advantage two, no scars. The unique selective photothermal principle of Feidun big Q skin pigment laser makes the laser penetrate the skin and act on pigment particles, without damaging normal skin tissues, which is safe and effective without leaving scars! Advantage 3. The treatment effect is good. Felton large Q skin pigment laser uses super Gaussian beam technology, also known as flat-topped beam. It corrects the light distribution of Gaussian beam with strong center and weak edge, obtains very uniform spot quality and ensures the best curative effect. Editor: Zhu Hua Brand
