Photorejuvenation is a non-surgical cosmetic procedure with good results. It is usually done once a month, and 3-6 times are needed for a course of treatment. Photorejuvenation is a common cosmetic procedure in beauty institutes, which uses broad-spectrum light to directly irradiate the skin. The broad-spectrum light can reach the deeper layers of the skin, decompose the pigmentation and stimulate collagen growth, which can help remove wrinkles, spots and improve facial pigmentation. After photorejuvenation, you need to let the skin repair itself. The skin metabolic cycle is 28 days, so you usually do it once a month. However, it is recommended to follow the professional doctor’s advice and choose the right treatment cycle according to your skin condition. After doing photorejuvenation, you should pay special attention to physical sun protection, such as playing umbrella, wearing sun hat, avoid drinking alcohol, eating chili, often touching your face with your hands, wash your face with cold water, don’t stay up late, and keep good habits of life and rest.
