A red nevus is actually a capillary nevus. It appears as a red, mole-like change in the skin in the form of a dot. Most of these nevi do not require treatment, and most of them will heal by themselves and will absorb and fade away, while others will dry up and fall off automatically. Of course, there are some nevi that do not fade for a long time, and some even grow up and need to be treated with laser in time. Generally, fractional laser or carbon dioxide laser can be used for cautery treatment. For red moles, if they are accidentally broken, the bleeding is not easy to stop, so try to avoid external damage in general.
