The lines are two lines extending down the side of the nose, which can be improved by injections, photoelectricity treatment, surgery and so on. 1. Injection filling: patients with more obvious lines and less obvious skin laxity can improve their appearance by injecting collagen, hyaluronic acid, autologous fat and other fillers. 2. Photoelectricity treatment: People with heavier lines can undergo radiofrequency treatment, which can promote collagen fiber contraction, repair and regeneration through the photothermal effect of photoelectricity that causes thermal damage to the deep fascial tissues, similar to ultrasonic scalpel, Thermage, and so on. You can also use intense pulse photon, through the photochemical effect, the dermal collagen fibers to restore the elasticity, eliminating wrinkles. 3. Surgical treatment: obese people with heavy lines can use facial liposuction to eliminate excess fat. You can also use thread sculpture combined with face lifting, using absorbable threads implanted into the superficial and deep layers of subcutaneous fat, to lift the skin and improve the lines. There are many treatment methods for the appearance of lines, and it is recommended that patients go to a regular hospital and choose the appropriate method according to their own situation.
