Liposuction fibrosis is a condition where scar tissue develops after liposuction, leading to hard, uneven lumps or tightness in the treated area. It occurs due to excessive collagen production during the healing process. Symptoms may include skin irregularities, discomfort, and stiffness. Treatment options include lymphatic drainage massage, ultrasound therapy, and radiofrequency treatments to soften and break down fibrous tissue. Compression garments can also help reduce swelling and prevent further fibrosis.
