Reasonable pressure of body shaping underwear acts on the breast, which can make the glands and connective tissue in the breast strong and beautify the breast. At the same time, the special material of body-shaping underwear has a gentle massage effect on nipples and mammary ducts, which can increase the secretion of female sex hormones and regulate female endocrine well.

Second, wearing body-shaping underwear is a health need. When women reach the age of 25, fat begins to accumulate, and women's secondary sexual characteristics gradually weaken. Body-shaping underwear can drain and locate fat, so that fat can be distributed reasonably. At the same time, products made of special materials can enhance human immunity and play a special role in health care, physical fitness and disease prevention.

This physiological pressure can make the psoas and abdominal muscles strong and break the living space of fat.
