Answer

Keloids manifest as exaggerated growths of scar tissue, usually in areas of previous trauma. Keloids extend past the areas of trauma, projecting above the level of the surrounding skin, but they rarely extend into underlying subcutaneous tissue.

Hypertrophic scars remain limited to the traumatized area and regress spontaneously within 12-24 months, although regression may not necessarily be complete.
