Can a Breast Lift/reduction Tighten Bra Rolls on Your Back?

Every doctor has different post op instructions so you should ask your surgeon what would work for you. The dressings vary from patient to patient. Some patients may be placed in a sports bra; others will wear a stabilizing elastic support strap. Your doctor will decide after surgery and in subsequent weeks, which dressing will suit your needs and how long you would need to wear them.

Breast Reduction does just that, it removes breast tissue, skin, elevates the nipple, and "lifts" the breast.  It is not intended to help the back or sides.  With that said I usually liposuction the area lateral to the breast on the side of the chest with every reduction.  Many women with large breast have a roll of fat there and it looks funny if not liposuctioned at the same time.  It adds maybe 5 minutes to the case and is done with syringe liposuction cannulas.  If there is loose skin it may not help that, and additional surgery, not covered by insurance for breast reduction may be needed.

Bra rolls are a combination of fat and loose skin. A breast reduction wil not help this.  A direct excision or liposuction can.

Always best to ask this type of question of your chosen plastic surgeon,  who is in the best position to provide you with meaningful and realistic advice/expectations.  Best to ask this question of your plastic surgeon while demonstrating your areas of concern in front of a full-length mirror.

 Generally speaking, I would caution you  about expecting much, if any tightening of "bra rolls"  after breast surgery is performed. If this is a major area of concern, liposuction surgery may be an option.

 Best wishes with your upcoming breast reduction procedure; this operation tends to be one of the most patient pleasing operations we perform.

A breast reduction removes breast tissue and skin to reposition and reshape the breast but does not actually "tighten" the skin and has no lasting effects outside the surgical area. 

Liposuction, including ultrasonic liposuction, reduces fat cells and does not tighten the skin. 

Rolls in the back or along the bra line beyond the breast may be helped somewhat by liposuction if there is excess fat in that area. If it is a skin or connective tissue laxity as in skin and connective tissue sagging from the underarms, the only reliable treatment is excision and trading for a scar. 

Im not sure I understand the question, A reduction mammoplasty tightens the skin somewhat in the anterior axillary line, the axilla,and the inframammary area. It does not change the tissue bulging around the bra on your back. If that is a problem then I like to do ultrsonic lipo in those areas in a prone position, prior to the reduction.  Traditional lipo may be needed around the breast if the excess tissue in the ant. axillary line and axilla are not improved enough by the reduction.
