What causes darkening of the nipples?

Darkening of the nipples may be caused by various factors. Physiological changes such as pregnancy, hormonal fluctuations, or genetic factors can all lead to darker nipple pigmentation. Excessive friction from sexual activity or wearing ill-fitting bras may also contribute to this condition. With aging, decreased skin metabolism and increased activity of melanocytes can easily result in pigmentation and darkening of the nipples. These are all normal physiological phenomena that typically do not require special treatment. If accompanied by other discomforts or symptoms, it is advisable to seek medical attention promptly to rule out potential health issues. In daily life, maintaining healthy habits and wearing properly fitted bras can help prevent nipple darkening.
