Usually, the methods of freckle removal mainly include laser removal and medication removal. Laser freckle removal is usually without much risk, but it is accompanied by some side effects. If the patient is allergic to laser, a series of skin reactions will occur. After laser freckle removal, there will often be scabs on the affected area. If the scabs are removed artificially, it may produce infection or pigmentation, or even scarring, and accompanied by some redness, swelling and discomforts, which can be appropriately iced to alleviate the symptoms. In addition, the treatment area of laser freckle removal is very sensitive to sunlight, so within 3 months to half a year after treatment, sunlight should be avoided and sunscreen products or umbrellas should be used as much as possible, which can improve the treatment effect, and more vitamin C should be added in daily life, which can promote the metabolism of melanin. Drug spot freckles can only get rid of part of clear freckles, which is suitable for patients with few freckles, deep color and clear freckle boundary. For freckles that are fuzzy or have not grown yet, they cannot be removed and may need multiple treatments in the later stage. In addition, if the lesions are exposed to water or other external stimuli, it may cause skin infection or the scabs will not come off easily. If the freckle scabs are washed off at one time, there may be a large area of pigment reflux and the fading speed is very slow, and the recovery of serious cases will take a long time.
