Your symptoms may be nipple inversion. Before puberty, women's breasts are undeveloped and their nipples are very small. After puberty, with the change of hormone level in the body, menstruation comes, breasts begin to develop, and nipples gradually increase and protrude. Although the nipples of unmarried women and pregnant women are small, they all protrude from the areola plane; If part or all of it is lower than the areola plane, or even sunken in the opposite direction, it will be trapped under the skin surface and form a local crater shape. This condition is nipple invagination (nipple depression). In particular, some girls are shy about breast development, so they wear tight underwear to tighten their breasts, or wear a bra that is too small too early, and the developing breasts will be squeezed and flattened; At the same time, the poor blood circulation and insufficient nutrition supply of the oppressed breast will affect the normal development of the breast; The nipple is also deeply immersed in the breast due to being squeezed, forming nipple invagination (nipple depression).

Correction of nipple depression:

Straight breasts are the focus of women's beauty, and nipples are the "delicate points" in the focus. If nipple invagination (nipple depression) is found, women had better correct it in time. The following methods can be selected according to different situations: 1. Manual traction. Adolescence is an important period of breast development and correction of nipple invagination. Often pulling the nipple can make the breast protrude, increase the supporting force of the surrounding skin, and play the role of "shaping". Several times a day. After a long time, the nipple naturally protrudes outward. If you can't pull it out, you can first push the skin near the nipple of the breast outward; The second is breast pump therapy, which sucks the nipple several times a day with a breast pump and uses its negative pressure to promote the nipple to swell out; Third, the use of nipple orthosis is to treat nipple flattening or depression.

Prevent nipple depression;

First, pay attention to clothes. Close-fitting underwear should be made of cotton, changed frequently and exposed to more sun. If the nipple shows signs of redness and cracking, the underwear should be cooked and disinfected, and it is not too early for girls to use bras.

Second, prevent extrusion. Underwear and bra should be suitable, not too tight. For girls with big breasts, more attention should be paid to the looseness of breasts. For girls who have prone habits, it is necessary to correct them in time to prevent nipples from being squeezed, so as not to aggravate the degree of nipple depression.
