What is a red pimple after a mole?

It is normal for a red pimple to appear after a mole. After a mole, a red mark will appear temporarily at the site of a pigmented mole. No matter what method is taken to remove the mole, including liquid medicine mole, laser cauterization, liquid nitrogen freezing, etc., erythema will appear when the local skin is stimulated. This erythema will generally subside by itself.
