Does wearing one help lose belly fat? Simply wearing shapewear alone will not have a lasting effect on your amount of belly fat. The purpose of shapewear for daily use is to help hold in your tummy, making it appear flatter so that your clothes fit better.

Contrary to popular belief, fajas have no relation whatsoever to losing weight. They might give you a slimmer look and motivate you to go on a diet and exercise, but not more than that. Some compression garments also help tighten the skin, preventing the undesirable flappy skin look.

Fajas are designed to temporarily reshape your body while you are wearing the garment. You can “lose” inches around your waist and thighs, lift your buttocks and smooth problem areas such as belly or back bulge. The benefits achieved when wearing the garment will immediately be gone when you remove the faja.

Recommendations on How Long to Wear your Colombian Faja You'll be advised to wear your faja in some capacity for three months following your BBL. For the first six weeks post-op, you'll need to wear your faja 24 hours a day, only removing it for laundering and bathing.
