I found that at the age of 18, in the United States, women are allowed to get breast augmentation surgery, but only with saline implants. Due to FDA standards, women are not permitted to undergo breast augmentation with silicone implants until they are at least 22 years of age. Then I read; In general, it is best to have breast enhancement surgery when you are at least 18 years of age, if it is done for purely cosmetic purposes. At 16 years of age, your legal guardian must consent to breast augmentation for you. This may make your family and your surgeon uncomfortable. I found a doctor who says that he doesn't feel comfortable doing the surgery to anyone under 16 because of puberty reasons. He tells them to wait. So I have no idea what the age limit is, because I'm finding different things. But here's the thing, if you have the money, someone will look the other way and perform the surgery; regardless of the person's age.
