Breasts Continue to Change Throughout a Woman's Life

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.

Breast Development

Breast development typically completes itself shortly after puberty in girls, about the age of 15 or 18 years. Several factors can affect breast development and size both during puberty and throughout life. Some of these are genetic while others are not. Weight has a significant impact on breast size as does other factors that influence hormones such as pregnancy, breast feeding and menopause. How the breasts respond to the female hormones varies for each individual and can result in either a decrease or increase in breast size as well as change in breast shape. Breast shape also changes over time with changes in breast tissue support and skin elasticity. Breast enhancement, therefore, must be tailored to the individual. Seeking a board certified plastic surgeon trained in the nuance of breast surgery is important in getting the best results.

Early twenties

Your early twenties is the simple answer to when breast development is complete. Weight changes  will change breast size. Most breasts change significatly with preganacey and breast feeding. Young breasts are firm and gladular, as breasts age the gland tissue is replaced by fat and the breast gets softer.

When do breasts stop developing?

On average, most women are finished growing by age 18 although some might continue to grow into their early 20s. It is a good rule of thumb to not have breast surgery until your height, weight and breast size have been stable for two years.

However, your breasts can continue to change over your lifetime. Breasts, which are made up mostly of fatty tissue, are often the first indicators of increased weight. In addition, birth control pills and pregnancy can increase your cup size, sometimes dramatically. Your breasts can even vary with each menstrual cycle.

When does breast development cease?

This varies from person to person, but it coincides with the cessation of puberty in the absence of outside hormonal influences (either hormones produced abnormally by the body or ingested in some form or fashion). Breast size, however, can be influenced by many factors such as weight gain/loss, pregnancy (hormonal) or shrinking of the breast tissue after pregnancy or breastfeeding.

Breast development

Normally, your breasts stop developing anywhere from the ages of 18-25. If you havent experienced any changes in breast sizes after the age of 18, chances are your breasts have probably stopped developing since.

At what age do your breasts stop developing.

This is a great question and really has a few different answers. Most women start to notice an enlargement of their breast tissue around puberty. Puberty in women typically happens before most males and occurs anywhere from 9-16 years old. If a women has not noticed much change in her breasts after the age of 18, then they have likely finished "developing". Breasts can also change in size according to weight gain and loss. In addition, when a women becomes pregnant, the breast tissue is stimulated to "grow" in order to prepare for lactation.

At What Age Do Your Breast Stop Developing?

Thank you for the question!  Your breasts are in stages of evolution throughout your life.  When hormones like estrogen and progesterone fluctuate, your breasts can change composition from densely glandular to a fatty composition.  Gravity also stretches breast tissue and ligaments to a lower position on your body when standing.  Breast reduction, augmentation, and lifts are frequent procedures performed to help achieve ideal breasts for women depending on their preference and medical needs.  I hope this answers your question!
