① Natural Aging
As women age, the body's natural collagen production gradually declines. This reduction affects the firmness and elasticity of the skin and supporting tissues, causing breasts to lose their youthful shape and volume over time.
② Pregnancy & Breastfeeding
During pregnancy, breast tissue expands significantly. After breastfeeding ends, the tissue often shrinks, but the surrounding skin and support structures may not fully return to their original condition. This can contribute to volume loss and sagging.
③ Weight Fluctuations
Repeated cycles of weight gain and weight loss can place significant stress on breast tissue. Over time, these changes may weaken the breast's natural support network and reduce overall firmness.
④ Gravity & Daily Wear
Every day, gravity continuously pulls on breast tissue. Over years and decades, this constant downward force can gradually stretch the structures responsible for maintaining breast shape and support.
