Method one. Bra method: Choose a bra with appropriate size to avoid or correct the bad habit of corset, so as not to further aggravate nipple invagination. At the same time, open a hole about the size of a nipple in the center of the bra. After wearing a bra, the nipple is squeezed out and kept in a prominent position.

Method 2: Negative pressure method: the syringe can be sleeved on the nipple, or the nipple can be fastened with a small wine cup, pressed with a cloth belt, sucked out with cupping, or flattened with a plastic jar and buckled around the nipple, so that it can be attracted when released, and it also plays the role of cupping.

Method 3: Manual traction: The girlhood is an important period for breast development, and it is also an important period for correcting 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.

Method 4: Sucking therapy: After pregnancy, use a breast pump to suck the nipple several times a day, and use its negative pressure to promote nipple swelling.

Method five. Use nipple orthosis: nipple orthosis can treat flat or sunken nipples.
