Is it Possible to Make Muscular Arms Smaller?

Even though your arms are muscular there may be some fatty tissue on the back and lower sides that could be sculpted.  See a board cerified plastic surgeon to see if you have any operative possibilities.  Good luck!

Thank you for your question regarding how to make muscular arms smaller. The arms consist of four significant types of tissue: skin, fat, muscle, and bone. In this situation, we are not going to consider bone. To. Make your arms less muscular; you need to decrease the muscle mass in your arms. If you are working out, I suggest you do less weight training. That means less lifting with your biceps and triceps. Suppose that is not the issue. I do not necessarily suggest removing or shaving down muscle. Some plastic surgeons, however, advocate that, but in my opinion, it is too traumatic and can lead to significant blood loss and underlying nerve damage. Another option could be fat transfer. Fat can be harvested from the abdomen and love handles and be transferred to the areas on your arm. This would help to camouflage the underlying muscles. Typically this is an insertion of the biceps to the deltoid and the triceps to the deltoid. Fat can also be inserted on top of the muscles to camouflage the muscles. I hope this helps answer your question about helping your arms look more 'women' and less muscular.
I specialize in arm lifts. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty or arm crease fat grafting, please contact my office. Since a brachioplasty or arm lift surgery is a difficult procedure, please seek an experienced, board certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf.  Sincerely, Dr. Katzen.

                  In
theory, muscles can be surgically reduced, but this isn’t a commonly performed
surgical procedure for a variety of reasons. This procedure has the potential
for significant complications. In addition, this type of procedure might
adversely impact arm function. For these reasons, most plastic surgeons agree
that upper arm muscle reduction isn’t a good idea and as a result, they don’t
perform this procedure.

                  In
some cases, alternative procedures may occasionally be helpful when arm
reduction is desired. Under these circumstances brachioplasty and liposuction
might be effective in some cases.

                  If
you’re concerned about upper arm contour, consultation with a board certified
plastic surgeon is appropriate. This surgeon should be able to formulate a
treatment plan that’s appropriate for your problem.
