A third mole spotting can be performed. However, it should be noted that there should be a period of time between two mole spotting sessions, so as not to increase the probability of scar formation due to incomplete healing of the skin from the previous treatment. Usually, there are differences in the choice of mole spotting methods for different parts and sizes of pigmented moles. Common mole spotting methods include medicated mole spotting, laser mole spotting, etc., all of which are invasive operations, and the original skin lesion needs a certain amount of time to recover before the next treatment can be carried out, or else it will increase the risk of localized scarring. Generally speaking, if the pigmented mole is darker in color or larger in scope, and the effect of two mole spotting is not good, and a third mole spotting is needed, then it is necessary to have an interval of at least one month between the two mole spotting sessions before the next treatment, so as to avoid serious skin damage. If the location of pigmented nevus is assessed to be deeper or the area is larger (>3mm), surgical excision can be considered. It is recommended that patients go to regular hospitals for consultation and treatment, and do a good job of skin care after nevus spotting treatment, and strictly protect the skin from the sun.
