The light wave of freckle laser is aimed at black and brown pigments. These spots can absorb this laser and be decomposed. When the pigment is gradually absorbed by the body, the color will also change. Tattoos and tattoos belong to this pigment. Other vascular stains, such as hemangioma, can use dye laser, and the heme in the blood vessel absorbs the heat generated by the laser to make the microvessels contract and gradually return to normal skin. Spotted moles and freckles suitable for laser treatment: small brown spots from the tip of a needle to the size of a grain of rice, scattered on the cheeks and the bridge of the nose, generally have existed since childhood and have always existed. Nevus: Most of them appear gradually after puberty, ranging from several to dozens. There are large brown or black flat spots or protruding papules from the tip of the needle to the grain of rice, which are mainly distributed in the face and neck. Zygomatic nevus: After puberty, a cluster of gray-blue needle-like to rice-grain-sized spots gradually appear on both cheekbones or under the lateral sides of both eyes, and a few patients have family inheritance. Liver spot: Brown spots that gradually increase after the age of 25, and appear symmetrically on both cheeks. The color is similar to that of cooked pig liver, so it is called liver spot, which has nothing to do with liver disease. Ota mother spot: generally, gray-blue mottle appears in the upper half of a face, and even the sclera of the eye will have gray-blue, and the pigment is as deep as the dermis. Senile spots: a few to dozens of waxy, rough brown or papules and patches, and gradually increase, more common in sunburned parts such as face and back of hand. Sunburn: oval protrusion or smooth dark brown patch, which is easy to appear on the outside of forearm, back of hand, front of calf and face. It is about the size of rice grains to fifty cents, and it begins to appear in middle age. Light brown spots: generally, there are irregular light brown spots at birth. Tattoo: Pigment is artificially implanted into the dermis, or pencil lead and iron powder enter the dermis due to accidental injury. These symptoms of spot nevus can be removed by laser, and the number of treatments depends on the depth of pigment. Second, most of the dermabrasion uses carbon dioxide laser, which is suitable for removing wrinkles, scars, small wrinkles on the face and dents left by acne, and is not suitable for scalding scars. Laser therapy can smooth fine lines and scars and make skin or scars smoother. Because of the high intensity of carbon dioxide laser, it directly radiates heat energy to the skin, which makes the subcutaneous tissues such as collagen compact and makes the skin rejuvenate. In order to reduce light lines and even remove uneven scars on the face, laser peeling is much more important than fruit acid peeling. Compared with laser, the effect of fruit acid on skin cells is relatively slight, and the ability of laser to penetrate the skin is several times higher than that of fruit acid. It is considered as a kind of skin rejuvenation and stronger than fruit acid. With carbon dioxide, the effect will be more detailed, which will tighten loose skin. The advantage of laser dermabrasion is that it can accurately control the number and depth of dermabrasion. The heat energy generated by laser can seal blood vessels, and the wound is dry and dry, which greatly reduces the chance of infection and accelerates healing. Third, hair removal In recent years, lasers have also been applied to hair removal. Axillary hair, leg hair, beard, or hair with conspicuous corners of women's mouths are all suitable for laser hair removal. The principle is that melanin in hair follicles will absorb the energy of laser and destroy hair follicles through heat exchange. The energy of laser can enter the hair follicle along the hair shaft, and the hair follicle will be destroyed by the energy, so that the hair will stop growing.
