Where is the areola?

Generally speaking, the development of female nipples and mammary glands is different, and the color of nipples is also different. The main reason of areola blackening is the aging of cells and the secretion of female hormones, which leads to melanin precipitation in nipple epidermis.

Therefore, breast blackening is a symbol of women's physical maturity. Women who have a good sexual experience will also grow plump breasts and become more elegant and charming. Generally, the areola of people with white skin is light chocolate, and the areola of people with yellow and black skin is darker.
