Freckles are usually difficult to get rid of completely. Freckles are a kind of skin abnormality with increased epidermal pigmentation, which can usually be removed by combining different photoelectric devices and methods to help pigment metabolism, but the disease is an autosomal dominant disorder and recurrence may occur. Most of the freckles appear around 3-5 years old, with more female patients, and their number tends to increase gradually with age. Freckles tend to appear on the face, with the nose and cheeks being more obvious, and can involve the exposed parts of the neck, shoulders and back of the hands. Freckles are genetically related, and all treatments can achieve transient or stage relief, after a period of time, there is a possibility of recurrence, so there is no way to get rid of freckles completely. In addition, after the freckle removal surgery, you need to pay attention that you cannot get water on the area for a week, and you can only use cotton swabs to wipe around to avoid bacterial infection. In daily life, try to avoid sunlight to prevent the aggravation of freckles.
