This is a great question. Although the FDA issues standard guidelines for breast augmentation at age 18, actual breast development is very variable from woman to woman. I explain more in the video.

Thank you for your question. Normally breast development is complete between 16-20 years of age. In addition your weight and medications can also affect breast growth.

Breast development occurs throughout puberty. The breast has usually completed its development by the age of 18. Although breasts finish developing at age 18 they continue to change throughout someone's life. This can be related to fluctuations in hormones or the use of birth control, changes in weight, menopause, or pregnancy and breast-feeding.

When do breasts stop growing?

In general, I tell my patients that breast development occurs through age 18.  That being said, your breasts will continue to change throughout your life, depending upon hormone fluctuations, pregnancy, and weight gain or loss.

Definitely varies from woman to woman, and is related to puberty, hormones, genetic make-up, and breast receptor sensitivity. It is safe to say that a woman's breast is usually developed by age 18.

Breast development is complete at the end of puberty.Therefore, depending on when that occurs on an individual basis, breast development will typically be complete in the late teenage years (16-18 years of age).However it is important to note that although development is complete, the breasts can still fluctuate in size throughout life due to certain factors such as pregnancy, breast-feeding, weight gain/loss or menopause.

Breast development correlates with puberty

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Breasts generally stop developing at the end of puberty-- around age 16-18 for most women. However, breasts continue to change with weight gain, weight loss, pregnancy, breast feeding, and age. Other things being equal, if you are a healthy young woman, you will have reached glandular breast maturity by age 18 or thereabouts.

Breast Growth

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
In general, breast development/growth ceases between ages 17-21 years.  A woman's age and breast growth is taken into consideration by plastic surgeons when discussing certain breast procedures with patients, especially younger patients.  That being said, breast size and shape never stop evolving during a woman's life and are affected by such things as pregnancy, breast feeding, weight gain/loss, and menopause.  These things will also affect a woman's breasts after having surgery such as breast augmentation, reduction, or lift.

Breast development is completed by the age of 16-17 for most women.  Because the breast is a gland, it may increase or decrease in size during adulthood, with weight gain or loss and childbearing. Many women experience increase or decrease in breast size after children.  This so normal.  You should ask your plastic surgeon about this if you are interested in breast surgery.

Approximately between the ages 16-21-- when puberty ends. Although, there are cases of significant increase in breast size in a mid 20s or later. There does not appear to be a clearly identifiable time when breast growth absolutely stops. Generally speaking, by the time a woman is 21yo-- she can count on that being her final size.
