My areolas have enlarged quite a bit, but difficult to say if it is pumping or the herbs making them larger. My guess is the combination.
I have 3 different sizes of suction devices, plus a spectra pump. The smallest one is little over 1" which really makes the nipple itself huge. The medium one is about 2.5" and really expands the areola and nipple. The large cups (5.25") make the entire breast swell, including the areola and nipple. I am using a mix of PM, Fenugreek, Fennel, on my chest as a "lube" for the suction cups, leaving it thick on the nipples and areolas.
The color of my areolas becomes much darker and the skin softer / more sensitive when I am using herbs vs pumping by itself. Mine are currently a bit more than 1.5" in diameter when relaxed, and look between 2" or 2.5" when under suction. I would love to have them over 2"+ and deeper brown in color, even when not pumped.
