There is no perfect age for breast augmentation, but you must be at least 18 for saline breast implants and 22 for silicone breast implants. While the average breast augmentation patient is typically in her 30s, many women increase their breasts in their 40s, 50s, and older. Whether you're a young woman with asymmetrical or small breasts or an older woman struggling with the effects of childbearing and natural aging, breast augmentation can provide beautiful, natural-looking results.
