In most cases, moles will not leave scars, but each case needs to be analyzed. If a person has a scar, the possibility of scarring is generally higher than that of other people. In addition, whether a mole will leave a scar or not is also related to the nature of the mole, the operation method and the care method, so it is recommended to choose carefully.1. Nature of the mole: mole spotting is mainly suitable for small and shallow growth of hemorrhoids, so the damage is usually limited to the epidermis, which is easier to recover and usually will not leave a scar. If the mole is not confined to the epidermis and reaches the dermis or is larger in size, mole spotting may damage the dermis or damage a larger area, which may leave a shallow pit and leave a scar; 2. Operation method: Improper operation during mole spotting may leave a scar on the skin. For example, if you use electrothermal high temperature cautery, you may not be able to control the degree of cautery, which will leave scars; or if you use chemical corrosion or liquid nitrogen freezing, you may not be able to control the depth of corrosion or freezing well, which will leave scars; CO2 laser mole spotting also requires high skills of doctors, and improper operation may leave scars. Therefore, you should choose a professional hospital and seek the help of professional doctors for treatment; 3. Care method: Failure to keep the wound dry after mole spotting or scratching the wound causes wound infection and thus leaves scars. After surgery, ensure that the treatment area is dry, and use a clean towel or gauze to absorb the water as soon as possible after washing, bathing or touching water. Sunburn in the treated area can also easily lead to hyperpigmentation, so you need to pay attention to sun protection. You also need to pay attention to your diet and avoid spicy and irritating foods.
