Sun spots usually do not require treatment and can fade away on their own; if they affect aesthetics, they can be removed by general treatment, medication and laser treatment. 1. General treatment: Generally for patients with mild symptoms, sun spots may subside by themselves. In normal life, patients should avoid re-exposure to sunlight and pay attention to applying sunscreen. 2. Medication: under doctor’s guidance, patients can use decolorizers, such as hydroquinone cream; they can also use drugs with whitening function, such as arbutin; they can also take vitamin C and tranexamic acid orally, which can help to lighten the pigmentation. 3. Laser treatment: patients can also remove sun spots through laser treatment. By utilizing the photothermal principle of laser, the melanin particles will be shattered and metabolized through lymphatic circulation to remove sun spots. It is recommended that patients with the need of removing sun spots should go to regular hospitals in time and standardize the treatment under the guidance of doctors. In daily life, patients should pay attention to sun protection, avoid prolonged exposure to sunlight, maintain good mood and ensure enough sleep.
