The effect of laser spot removal is still relatively good, fast and convenient, and less traumatic, but it is only effective for superficial spots. Laser spot removal is one of the more commonly used methods to remove spots in clinical practice at present, and its mechanism of action is to form a specific wavelength laser through high-intensity visible light energy, which acts on melanin particles in the surface layer or even the deep layer of the skin, and shakes the pigment particles into a fine sand state, and then discharges them out of the body by way of descaling and metabolism, so as to achieve the purpose of fading pigmentation and getting rid of spots. However, laser spot removal is mainly used for superficial skin spots, and for spots deep into the skin, generally speaking, its laser treatment effect is not very obvious, and the same will recur after treatment. In addition, it should be noted that after laser spot removal, we should ensure that the skin is not infected and clean regularly.
