There are several reasons for the dark areola color: 1. Pregnancy. Hormonal changes cause darkening of the areola. Even if hormones gradually return to normal after childbirth, the color of the areola is unlikely to return to its pre-pregnancy appearance. 2. Over-stimulation. Excessive sexual life, infant sucking breast milk and the preference to wipe the body with a sponge, improper exfoliation, etc. can cause pigmentation and darkening of the areola. 3, wearing rough underwear, if the material of the underwear is rough, constantly rubbing the areola and nipples, can cause melanin deposits. 4, where women have higher levels of estrogen, there will be black nipples, which is a healthy female characteristic, after menopause The nipples and areolas will appear pink because of low estrogen levels in women. Therefore, we cannot judge a woman’s sexual experience or whether she has given birth because of her dark nipples or dark areolas.
