Q-switched laser technology can penetrate the epidermis of the skin and reach the deep layer of the skin immediately after the super pulse time of milliseconds and microseconds, so that the pigment particles inside the skin are immediately crushed, and the crushed pigment particles will be swallowed up by human macrophages and slowly transported away. This laser technology is because the laser with a specific wavelength can reach the diseased pigment tissue through epidermis and dermis, and only works on pigment particles. Therefore, without damaging normal skin, applying the principle of different wavelengths has no obvious damage to skin texture, so it will not leave scars on the skin. Although the treatment effect is almost perfect, the conditioning after treatment can not be ignored, because you are not careful, you may leave traces. Therefore, within two weeks of laser treatment: do not scrub the treatment site with water, be sure to pay attention to the cleaning of the wound surface, and prohibit early scabbing and let it fall off on its own; After laser freckle removal, skin redness is normal due to energy, but it will soon fade away; The most important conditioning is to use sunscreen to avoid sun exposure. ? I believe you should understand after such a detailed explanation. Laser freckle will not leave scars, and there is no need to filter. Choose a regular plastic surgery hospital and experienced doctors to ensure your treatment effect and safety.
