Why do I don't have breast growth after I turned 18? They are just minimum size until when I was 16

Thanks for your question!
Typically your breasts stop growing when you are through puberty. If you are interested in a breast augmentation, schedule a consultation with a board certified plastic surgeon to discuss your options. Best wishes!

Many women never develop much breast tissue. Most women have breast growth up to age 22. By 18, your breasts have achieved most of their volume. Many women with underdeveloped breasts will get a breast augmentation at age 18 or shortly thereafter.

If interested, I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what is right for them.

Breast size typically increases during puberty. The amount of breast growth you have is determined by many factors and is uniquely you. You may also experience breast growth during pregnancy and breastfeeding. If you are wanting larger breasts you can consider breast augmentation. Visit with a board certified plastic surgeon if interested in learning about implants and which would be helpful in achieving your desired look.

Most ladies are through growing in breast size between 15 and 16 years of age. The next change may be with pregnancy and breast feeding or with weight gain. Genetically, you may not be destined to have much growth.

Breast development is complex and multifactorial.
A lot of this is genetically predetermined. Some people have breast tissue that is very sensitive to hormone stimulation while other individuals breathe do not respond to hormone changes as much.
