Thank you for the question. The bumps on the chest may be keloids, and these may have arisen from previous acne or injury to the area. It is advisable for you to see see your doctor or dermatologist for a proper examination to confirm the diagnosis.
For keloids on the chest, intralesional injections with steroids is a good treatment to reduce the size and thickness of the lesions. A few injections may be needed for the best results.
