Medical Although good breast care primarily means keeping your breasts healthy, for some women it also means keeping your breasts smooth and firm. There are two reasons for breast to sag: large breasts and age. Somewhere between the age of 30 and 40, the elastic tissue in the breast begins to degenerate. The breast fibers, which act like rubber bands and provide that resilient bounce as you walk, will still stretch, but they don't snap back quite as well. The result is saggy breasts with a few stretch marks thrown in for good measure Adding to the problem, hormonal changes - both during pregnancy and as you reach menopause - make breasts sag even more. During pregnancy, the hormones estrogen and progesterone, which are secreted by the ovaries and the placenta, stimulate development of the 15 to 20 lobes of milk-secreting glands embedded in the breast's fatty tissue. These changes are permanent. And although the glands may be empty after they're no longer needed to produce milk, they will still add bulk and firmness to the breast.  Once menopause arrives, however, the drop in estrogen and progesterone signal the breast that its milk ducts and lobes can retire. As a result, the breasts shrinks, add fat and begins to sag over and above the demands of gravity. Fortunately there are three ways to prevent, and sometimes reverse, both saggy and stretch marks breasts. There is no way I know of to build up the breast's fatty tissue, but you can build up the muscle tissue under the fatty tissue or lose the fatty tissue. One way to have nice firm breasts is avoiding weight gain and the resulting excess fatty tissues. Also, exercise will prevent or reduce saggy breasts. Two pound dumb bells will do it. With a weight in each hand, extend your arms out to each side and do 15 small, backward circles about a foot in diameter. Widen the circles slightly and do another 15, then repeat these two steps going forward. Body Cream with aminophylline, has also been effective in reducing fatty tissue in the breast areas. If you have stretch marks on the top and sides of your breast area, you can treat them with daily applications of alpha hydroxy, vitamin E, cocoa butter, aloe vera, and collagen cream. This combination of vitamins, fruit acids and essential oils will also help stretch marks in other areas as well. Increase your protein intake. Protein is needed to build and keep muscles tone and firm. Protein also provides much needed Collagen. Three to four meals a day that consist of protein is recommend.
