Mostly all women have little bumps on their areola and the darker colored skin around the nipple area. This is normal. Some women have more or less bumps and this is normal too. The medical term for them is “periareolar glands of Montgomery.” They play a role during lactation (during the time when a woman’s body makes breast milk).
We are not aware of any medical treatment to change the color of a woman’s areola or to reduce the number of the glands. Home remedies that you might read about online that claim to do either, have not been well tested and therefore could be unsafe. Never squeeze the glands on your areola. This can cause inflammation and possibly, infection.
