Breast enlargement surgery can be done non-surgically in a few different ways. 1. Silicone gel implants: These are the most popular type of breast augmentation surgery and are believed to be the safest method of breast enhancement. The implants are placed under the muscle tissue of the breast and slowly release over time, creating an appearance of larger breasts over time. 2. Submuscular implant placement: This technique involves placing the implant directly beneath the muscle tissue below the bust line. This is thought to provide a more natural appearance as the implant doesn't appear bulky or fake. 3. Fat grafting: This is a less common but still effective way of achieving breast enlargement without surgery. In this procedure, some fat is taken from other parts of the body and injected into the breasts to help them become larger.
