Sunburned freckles need to be dealt with through general measures, medication and physical therapy. 1. General measures: patients need to do a good job of personal protection when going out, take relevant sunscreen measures to avoid excessive exposure to sunlight, and at the same time need to keep the skin clean and hygienic and avoid staying up late at night. 2. Medication: For patients with lighter freckles, it is necessary to use 30%~35% trichloroacetic acid solution or phenol spot-coating under doctor’s guidance, which can make the local epidermis peel off. At the same time, 3% hydroquinone cream, 0.05% retinoic acid cream, vitamin E cream and other drugs should be used according to the doctor’s instruction. 3. Physical therapy: Clinical physical measures for treating freckles include strong pulse laser, Q-switched ruby laser and so on. It is suggested that patients with freckles should strengthen the management of daily life, keep positive and optimistic mentality, go to the hospital in time and follow the doctor’s instruction to standardize the treatment.
