Sun spots, i.e. solar dermatitis, are caused by strong ultraviolet radiation, which can be eliminated by local cold compress, medication and physical therapy. 1. Local cold compress: after a long time of sun exposure, cold compress gel and low-temperature saline should be used immediately to reduce the local temperature, so as to shrink the capillaries and reduce the skin lesions. 2. Medication: under the guidance of professional doctors, glycerite lotion, mometasone furoate gel and other drugs should be applied on sun spots, which can help astringent, anti-inflammatory and anti-itching. If there is pain in the sun spot, oral diclofenac sodium can also be prescribed to reduce inflammation and pain. 3. Physical therapy: for example, strong pulse light, picosecond laser treatment and other methods can effectively remove pigmentation after sun exposure. To summarize, for summer sun spots on the face, you should consult a doctor in time and follow the doctor’s advice to take the appropriate method of treatment. Moreover, you should pay attention to sun protection and avoid going out when the sunlight is strong.
