According to HowStuffWorks, acne scars never go away completely, but they can eventually become largely unnoticeable. A number of treatments for acne scars are available.
HowStuffWorks states that no scar ever goes away entirely. A scar is formed due to damage at the dermal level of the skin, which is where new skin cells come from. When a wound heals, new collagen fibers appear to repair the damaged tissue, causing a scar. Treatments for acne scars can make the scars lighter in color and smaller in size. There are surgical options available as well as laser therapy and a number of less invasive procedures.
