Hypertrophic Scar

A hypertrophic scar is a large, raised, hard scar caused by severe acne. This type of scar looks like a large lump of firm tissue, and is often much larger than the original acne blemish that caused it. Also known sometimes as a keloid scar, a hypertrophic scar is caused by the overproduction of collagen, and most commonly forms on the torso. Unlike pitted acne scars, which can often be treated with injectable fillers, a hypertrophic scar can be more difficult to remove. Often, these types of scars grow back after removal, making them especially resistant to treatment. There are, however, treatment options available. Steroid treatments may be affective in treating hypertrophic scarring. Steroids may be applied topically or injected. Laser treatments may also reduce the size and appearance of a hypertrophic scar.
