Can filler be use on nipples for increasing the nipples?

Thank you so much for your question! You can absolutely use dermal filler to increase nipple projection. Dermal fillers last about 7-12 months depending on which filler is used. I recommend consulting with a board-certified plastic surgeon who is experienced injector and has experience in this procedure to make sure you get the best results possible.  

Yes, dermal fillers can be used to increase nipple projection.
The effects however are not permanent.

Simple solutions can to filler, such as Radiesse. Other methods can include a local flap of skin. However, that is generally reserved for reconstructive surgery.
