The Niplette gently creates a suction effect that draws the nipple into a small thimble-like plastic container. After several weeks of continuous use, the nipple remains erect. It is ideally used before pregnancy, but it can also be used during the first six months of pregnancy to achieve a long-lasting correction. If you have recently developed inverted nipples that are not congenital, you should consult your doctor before using the Niplette. Its use in the last third of pregnancy is not recommended. Clinically proven - the Niplette: a tool for the non-surgical correction of flat or inverted nipples.
