Tightening the Excess Skin Inside the Forearm? (photo)

Although your pictures are helpful, it's virtually impossible to make a specific treatment recommendation without a physical examination. Standard brachioplasty procedures don't impact the area below the elbow. When isolated upper arm lifts are performed, tightening the skin above the elbow can accentuate deformities below the elbow. I suspect this is what's happened in your case.When this situation arises in someone who's already had a brachioplasty, conversion of the original procedure to an extended brachioplasty is appropriate. This would involve extending the previous incisions across the elbow to improve forearm contour. This type of procedure involves trade-offs between loose saggy forearm skin and scarring. For this reason, it's important to thoroughly understand the pros and cons of extended brachioplasty surgery.Under these circumstances, it's appropriate to discuss your surgical options with your surgeon. Your surgeon should be able to formulate a treatment plan that addresses your anatomic findings and achieves your aesthetic goals.

Yes, there is a surgical procedure to remove excess skin and fat from your forearms. Not having physically examined you, I can only base my answer on your photograph. If your skin tone and skin elasticity is "good", I would suggest forearm liposuction.  After your forearm liposuction, compression garments will be essential for at least 2 months. If your skin tone is "poor", I would suggest an incision.  Typically, the forearm incision extends from the arm reduction or brachioplasty incision down the forearm.  This surgery will remove excess skin and fat from the forearm, however, the forearm scar is more visible.  Another alternative is to extend the incision around the elbow and draw the skin toward the elbow.  This scar is better concealed, however, this incision does not remove as much skin and fat.  
Either way, please find a Board Certified Plastic Surgeon with extensive experience in weight loss patients who has performed many arm lifts or brachioplasty procedures. I hope my answer has helped you.  Good luck.  

It is very likely that your existing arm lifting scar can be extended to eliminate the skin of concern. Discuss your questions/concerns with your plastic surgeon.

 Best wishes.
