After treatment, patients can wash their faces and make up immediately without affecting their normal work. It is the most ideal and scientific beauty method at present. Let's invite experts from Datong Qiqi Plastic Surgery Hospital to introduce them to you. On the basis of selecting indications, color-light rejuvenation can be mainly divided into type I and type II. Type I technology is suitable for the treatment of light damage, such as sun damage, pigmentation, freckles, benign vascular diseases and abnormal skin color, including telangiectasia, rosacea, laser wrinkle removal and erythema caused by other treatments. Type II technique is suitable for the treatment of skin injuries, including changes of collagen tissue, such as pores, elastic tissue degeneration and wrinkles. Color light skin rejuvenation technology can obviously improve skin damage in a single course of treatment. Experts from Datong Mu Qing Plastic Surgery Hospital pointed out that color light rejuvenation is a non-invasive photodynamic therapy with broad spectrum. When intense pulsed photons act on skin tissue, they produce photothermal and photochemical effects, which rearrange deep collagen fibers and elastic fibers, restore elasticity, enhance vascular function and improve circulation. How often to do color light rejuvenation depends mainly on the patient's specific physique and therapeutic effect. General skin problems can obviously improve the skin quality through a course of treatment, but it depends on your specific situation. The effect usually lasts for 2-3 years, but it is also related to the patient's skin and maintenance measures. As for the effect of skin rejuvenation after a few days, it should also be distinguished according to the function of treatment. If it is to remove spots and increase the production of collagen, it takes an average of 3 treatments, and some patients may need to receive about 5 treatments. It takes a period of treatment interval to rejuvenate the skin with colored light. After several months of treatment, the face will gradually become smooth. Generally, after a period of treatment, the skin condition will be significantly improved.
