For women, acne is the first problem, except for pigmentation. Many people think that UV rays are only available in summer, but in fact, UV rays are still very strong in winter, and people are prone to sun spots if they are under strong UV rays. Sun spots, also known as solar dermatitis and sunburn, are an acute inflammatory reaction of normal skin after exposure to sunlight, manifesting as erythema, edema, blistering, pigmentation and flaking. The intensity of the specific sun spot reaction is related to the intensity of light, exposure time, individual skin color, body type, race, etc. The four degrees of sunburn 【dehydration burst skin】the skin loses its luster after sun exposure, tight and dry, rough to the touch, local flakes, and a tingling sensation when using skin care products. Red Hot Sensitive】The skin is itchy and red, feels burning, as if it has a fever, accompanied by some dense small bumps, serious will appear red spots, edema, and even blisters and other allergy symptoms. After-sun fine lines】After sun exposure, the skin on the face is sagging and thinning, pores are enlarged, and the fragile parts of the skin, such as the corners of the eyes and mouth, are prone to fine lines as expressions change. [Dark spots] Not only is the overall skin tone one shade darker, but the existing spots also become visible after sun exposure, or new spots and patches of darkness appear on an otherwise fair face. Laser treatment for sun spots is different from the traditional treatment for sun spots in clinical treatment, and there is no strict age limit for laser treatment for sun spots. Since a certain wavelength of laser light is only absorbed by the pigment of the corresponding color, only the diseased cells absorb the specific laser light. Advanced laser technology for sun spots also allows control of the depth of the skin reached by the laser, with adjustable pulses that minimize skin damage.
