There are lots of different methods to correct gynecomastia. The size and shape of the gynecomastia can also vary. Because of this, some patients may need to wear it longer than others. I usually tailor my patients' postoperative guidelines based on all these factors. However, I tell most patients that they should expect to wear their garment up to 6 weeks. I believe that it decreases pain, prevents seromas (fluid collections), stimulates blood flow to the area, allows for skin contraction, and improves shape. Especially for those moderate to severe cases where their is an excess in skin, continuous wearing of the vest for longer than 3 weeks really is essential to obtaining the best contour in the long run. Regardless, follow your own doctor's advice as he or she will determine the length of time you should wear your garment based on your own situation and his technique.
