Introduction
Most moles do not fall off on their own. However, if a mole is small and located in an area prone to friction (such as along the collar or cuffs), prolonged minor irritation may gradually loosen its attachment to the skin, eventually leading to natural detachment. Additionally, during normal skin metabolism, a very small number of superficial moles might shed along with the aging stratum corneum, although such cases are rare.
Under normal circumstances, most moles do not fall off on their own; only a few may detach due to external irritation or natural skin metabolism. If you have any concerns, it is recommended to consult a doctor in advance. The specific analysis is as follows:
If a mole is small and located in an area prone to friction (such as near the collar or cuffs), prolonged minor irritation may cause its attachment to the skin to loosen, eventually leading to natural detachment. Additionally, during normal skin turnover, a very small number of superficial moles might shed along with the aging stratum corneum, although such cases are rare.
Moles that are stable in growth, deeply rooted, or classified as pigmented nevi or dermal nevi generally do not fall off spontaneously. These types of moles are firmly attached to the skin tissue and tend to persist long-term without external intervention. If they suddenly enlarge, change color, or exhibit other abnormalities, these issues will not resolve through self-detachment and require professional medical evaluation and treatment.
Avoid deliberately rubbing or irritating a mole. If a mole undergoes sudden changes or appears to be detaching but is accompanied by bleeding, seek medical attention promptly. Never attempt to remove a mole by picking or scraping, as this may lead to infection or other skin complications.
