My boobs are developing slowly but nicel

Hi Tina, I am about to order more product and had more questions. My boobs are developing slowly but nicely. Question? My nipples are at the bottom pointing angle lower. Could I use the cream only on the underside of my breasts to promote growth below the nipple area? I am hoping to transition from large man boobs to noticeable female looking boobs with the nipples centered on the breast.
