How Does Hypertrophic Scar Treatment Work?: Hypertrophic scar treatment involves various methods aimed at reducing the size, thickness, and appearance of raised scars. Hypertrophic scars form when the body produces excess collagen during the healing process, resulting in raised and often red or pink scars that can be itchy or painful. The choice of treatment depends on the scar's severity, location, and the patient's skin type. One common approach to hypertrophic scar treatment is the use of silicone gel sheets or silicone gel. These products help to hydrate the scar tissue, making it softer and less prominent over time.
