Hours of wear: The site states 10 hours minimum for therapeutic amount of time/for it to have effect, but that won't get you very far. 12 hours should be your minimum, 14-16 hours would be ideal. Apparently your body hits a plateau when it's fully engorged, usually at 18 hours. You won't see more growth/swelling after the 18 hours.
The growth rate of 14 hours of wear consistently is significantly greater than the growth rate of 10 hours of wear consistently. (A chart can be seen on the following link.) This link also discusses rapid, average and slow responders, how far back a skipped day will set you, how to judge how long it will take to get your desired size, ect.

"For growth using BRAVA ALONE (not before or following surgeries or fat grafts) the more hours worn the better, up to about 18. The body seems to hit a plateau once it is fully engorged, usually taking place about 18 hours. You won't see a difference from an 18 hr day & a 24 hr day. To wear it 24/7 on a regular basis would not be recommended for several reasons: the abuse to the skin and the domes, no time to have the minor maintenance to your sport box, (dry cleaning about 1 hr per 10 hrs of wear) and you would also need to buy more domes since they would certainly wear out much more prematurely.
The long term wear for 10 wks or longer could go on as long as a year without stopping,. then it would be best to stop for a couple months to avoid a more severe plateau where the cell splitting is not taking place. Then you could do another session after that break. It is not written in stone as to how much you would grow in the 2nd session it varies just as it varies from person to person for any growth. In this method of wear, you are gradually expanding skin along with the swelling of the underlying tissues, not over stretching the skin, just filling up as you go.
14-16 hours is a manageable pattern for many people, however some find they may have a personal limitation caused by over use, more skin issues or muscle tenderness but do fine with the usual 10-13 hours. Do what you can do, if you get reactions, back off find your own personal comfort zone.
Regarding a hand or turbo pump - it should NEVER be used if not being used as a pre-operative device to maximize the SKIN, not just the tissue. Using the hand pump or turbo device without getting surgery may cause sagging skin and or nipples. In this method (hand pump or turbo device), your goal is not to get growth, just skin expansion and tissue expansion but to over expand the skin in preparation for the procedure of lipo-filling (fat transfer), to fill in the excess skin that would occur. This is done for a shorter period, 4-5 weeks only before surgery. If using BRAVA ALONE without surgery or fat transfer, only do the recommended times (between 10 hours and 18 hours) and use the smart box or sport box from Brava to avoid unwanted results."
