Moles do not go away on their own.
A mole, also known as a pigmented nevus, can grow on any part of the body and can grow at any age. It is an abnormal proliferation of pigmented cells. Once created, it will not disappear automatically.
If it affects the aesthetics or has a tendency to become malignant, you can go to the hospital and use laser or surgery to deal with it. If the pigmented nevus is relatively shallow and small, fractional laser can be used. The principle of fractional laser is that by irradiating with a certain frequency of laser, the pigment cells will be broken, and the pigment cells will be swallowed by macrophages again to achieve the result of removing the nevus.
If the size of pigmented nevus is relatively large (>5mm), you can choose carbon dioxide laser or surgery according to medical advice.
