Dilute Hyaluronic Acid for Lipoatrophy: Three Cases and Literature Review.

Localized lipoatrophy, characterized by subcutaneous fat loss, can result from trauma, injectable drugs, panniculitis, or idiopathic causes, leading to outcomes ranging from self-resolution to permanent disfigurement. This case series presents a novel approach using dilute hyaluronic acid (HA) for three cases of lipoatrophy (trauma-induced, radiation-induced, and steroid-induced), with all cases showing notable improvement after one session. This approach represents a promising, low-risk alternative for managing lipoatrophy of various etiologies, with potential benefits for patient quality of life.
