1. Smoking: Carcinogen is a substance in cigarette that is not only capable of causing cancer in living cells but can also cause the elastin to break down in the body. These elastin fibers are responsible for skin elasticity throughout the body. In other words, elastin allows tissues, ligaments, skin etc. of the body to stretch out and shrink back. This means, excessive smoking introduces more carcinogens in your body thereby destroying the elastin which has the ability to hold these tissues and ligaments supporting the breast and may eventually begin to sag (fall).
2. Weight gain: Major fluctuations in weight can cause unnecessary stretching of the breasts. Maintaining a healthy weight will help women avoid the progression of unnecessary stretching. Typically, Women gain weight during pregnancy and then lose excess baby weight while breastfeeding. All these are stressful for our bodies. Weight fluctuations (especially in combination with breastfeeding) can cause ligaments that support your breasts and as a result, make them saggy. The goal here is to avoid rapid weight gain and aim for gradual weight loss. It’s these special types of proteins- collagen and elastin – that make the skin around our breasts firm. Extreme weight gain (more than 50 lbs) is stressful to these proteins, and may interfere with their production and can negatively affect skin’s elasticity.
3 .Genetics: Breast sagging and genetics. Where is the connection, you’d think? Actually, it’s a thin line. Since your genes do not only define your breast size, they also play an essential role in determining the strength of your ligaments, elasticity of the skin and breast tissue density. While there are no muscles to hold the breasts high up and perky, the ligaments are really what you are left with.
4. Aging: As a woman gets older, the ligaments that make up the breast tissue stretch and lose elasticity. As a result, breast fullness is compromised as the underlying support system of tissue and fat diminishes. A change may be particularly evident during menopause.
5. Gravitational pull: Years of gravitational pull takes its toll, especially on women with larger breasts. Proper support of the breast is very important in this case. Wearing a proper and supportive bra is important to maintaining breast shape and lift. Wearing a supportive bra is important to maintaining breast shape over a 30-to 40-year period.
6. Sunburn: Ultraviolet rays damage the skin and cause loss of elasticity as well.
