1. Choose a bra with the right size: avoid and correct the bad practice of corset. Bras that are too small and too tight will oppress the chest and affect breathing. Because women mainly breathe in the chest, a tight bra is like tying a rope to the chest, which limits the breathing movement and avoids the further aggravation of nipple invagination.

2. Pulling method: When the inverted nipple is found, gently pull the inverted nipple outward with your fingers every morning and evening. Gently massage the nipple with your thumb or forefinger, and pull it for 5- 10 minutes at a time.

3. Extrusion method: Use a smaller bra or a piece of cloth with a width of 10 cm to open a hole the size of a nipple. After wearing a bra or cloth, the nipple will be squeezed out, and the inverted nipple will protrude for a while. You can also buckle a walnut shell or porcelain wine glass on the nipple, put on a bra and press it for a while to make the nipple protrude.

4. Negative pressure method: the thick end of the syringe or glass eye drop bottle can be buckled on the nipple, and the thin end is connected with a rubber tube and then connected with a large syringe. By forcibly pumping air, negative pressure is generated in the bottle, thus deeply compressing the tissues around the nipple and making the nipple protrude. After the bottle is put away, cooperate with traction and massage.

5. Plastic correction method: If the above four methods cannot be effectively corrected, it can be corrected through plastic surgery.
