Freckles can be treated by general treatment, medication and laser treatment. 1. General treatment: Avoid excessive exposure to sunlight and suggest using sun hat and umbrella when going out in order to minimize the occurrence of freckles or reduce the deepening of freckle color. 2. Drug treatment: drug treatment is mainly used for patients with light color, and hydroquinone cream, vitamin A acid ointment, arbutin cream and azelaic acid cream can be applied to make the pigment peel off and promote the absorption of pigment, so as to achieve the purpose of treatment. 3. Laser treatment: laser treatment of freckles is based on the principle of selective photothermal effect of laser, which makes the pigment particles burst instantly without damaging the nearby tissues, thus promoting the metabolism and absorption of pigment to lighten freckles. If people with freckles have cosmetic needs, they need to go to regular hospitals in time and follow the doctor’s advice for better treatment.
