The body has a natural mechanism for growth and healing. When body tissue is placed under sustained tension it will grow. This principle is known as "tissue expansion" and has been used for over 30 years by physicians in various reconstructive procedures. The BRAVA System is an external tissue expander. The System applies a gentle three-dimensional pull, which places the breast under tension. This very gentle, sustained tension causes the cells to respond by replicating. With the BRAVA System, the outcome of proper usage is new breast tissue, resulting in larger, fuller breasts. Clinical research indicates that women who complied with the procedure experienced an increase in breast volume, which ranged from 35cc to 250cc of lasting tissue growth.

The Brava System is worn each day for at least 10 hours and then is removed for 14 hours. After the 10 hour period, the breasts will become swollen and enlarged, but will subside during the following 14 hours of rest. Each time the BRAVA System worn and removed is a BRAVA growth cycle. As the weeks progress, the amount the breast decrease in size during the rest phase will be less. This is due to actual tissue growth.

Many women have had great success with this system. Perhaps the products only downfall is its price. Compared to other breast enlargement solutions, Brava proves to be the most costly.

Beautiful Curves is a gentle vacuum pump system developed by a female plastic surgeon. A specially designed cup is placed over the breast and manually activated by the user. The gentle suction draws the body’s own fluids into the breast tissue causing it to become enlarged. Over time, and with repeated use, this will actually cause your breast to grow. The regular stimulation of the breast tissue signals the pituitary gland to increase the production and release of the female hormones responsible for breast growth. The therapeutic technique is called soft tissue expansion and works on the same principle as exercise of gently applied stress that increases the muscle cell size and stimulates new cell growth.

The Nature Day breast pump is another good choice in breast pumps. Similar to Brava and Beautiful Curves, the Nature Day breast pump works by expanding the breast tissue, cause cellular growth and signally the pituitary gland to increase the production of female hormones responsible for breast growth.

Although from a functionally standpoint it works similarly as other products, the quality of the product seems to be questionable. Additionally, the breast cups are only available in medium and large.
