What exactly is the areola?

The areola is the circular dark-colored area of skin surrounding the nipple of the human breast, particularly prominent in females. The word areola, meaning a colored ring around the nipple, originated from Latin.
Areola and nipple size vary among females, and it is normal to have small or big areolas. Adult women often have oval-shaped, big areolas, and pre-pubescent girls have smaller ones.
The areola in women has glands called Montgomery's glands that secrete lubricating oil. The oil protects the nipple and skin from chafing during breastfeeding.
Areolas in men are smaller and have no physiological function.
What is the normal size of areolas?
The size and shape of the areola and nipples vary greatly among females. Women usually have larger areolas and nipples than girls who have not yet reached puberty.
The human areola is mostly circular, but many women have large, oval-shaped areolas. The areola of sexually mature women averages around 1.5 inches, but some women can have big areolas, as big as 4 inches.
Lactating women and women with particularly large breasts may have larger areolas, which is entirely normal.
What is the color of areola?
The color of the areola can be anything from:
The areola looks pale among people with lighter skin tones and darker among people with darker skin tones.
Can the size of the areola change over time?
It is not uncommon for the size of your areolas and nipples to change throughout your lifetime.
- During puberty, your ovaries begin producing the female hormone estrogen, which causes your breasts to grow. As your breasts continue to become bigger after puberty, your areola will appear smaller in proportion.
- During pregnancy, your areola may become darker and appear bigger due to the hormonal surge to prepare your breasts for breastfeeding.
The areola is part of the skin, which means it can stretch when you gain weight. As your breast gets bigger, your areolas may grow big too. Your areolas may or may not return to their previous size after you lose weight.
What are those bumps on the areola?
Montgomery glands are normal sebaceous glands on the skin that appear as small, painless bumps on the areola. Every person has Montgomery glands, though they are more apparent in some than others.

What determines a woman's areola?
Genetics plays the primary role in the size, shape, and color of a woman's areola, or a man's areola, for that matter. Areola characteristics are inherited, just like the color of eyes, the shape of the nose, or the texture of hair. Later in life, weight changes, and hormonal changes during puberty, periods, and pregnancy can alter the appearance of a woman's areola. Changes during periods are temporary and return to baseline after the period ends, but after pregnancy and breastfeeding, the areolas and nipples may not get back to their earlier appearance.
Can you fix large areolas?
Large areolas are not anything abnormal that requires "fixing," but it is possible to have cosmetic surgery to alter the appearance of your nipple and the areola.
Why is my areola protruding?
You may have protruding areolas simply because you have inherited them. They may start looking more noticeably protruding after puberty, with increased hormones.
Other reasons why your areola may protrude include:
- Excess fat tissue behind the nipple-areola complex. This may be genetic or from being overweight.
- Increased estrogen levels before a period.
- Certain medications, such as antipsychotics, cardiovascular medications, and others, increase the levels of prolactin, a hormone that stimulates milk production and breast tissue growth.
- Pregnancy and breastfeeding cause the oil glands in the areola to enlarge in order to provide sufficient lubrication to the nipple.
- Chafing from clothes during exercises is temporary.
Do areolas darken before your period?
Areolas can temporarily darken before your period because of increased estrogen production. When estrogen levels go up, melanocytes, the skin cells that produce melanin, produce more of it. Melanin is the pigment that gives skin its color, and increased production makes the skin darker. Once estrogen levels drop after the period ends, the areola reverts to the original color.
