How long does it take for untreated scars to fade?
Depending on the scar type, scars can take up to two years to fade naturally[2]. After the two-year mark, it’s unlikely your scar will fade anymore [2].
Scarring is a natural part of the healing process following tissue damage[2]. Most wounds cause the skin tissue to break, releasing collagen[2].
Collagen is a protein that is often associated with fuller, younger-looking skin. When your skin tissue breaks, collagen builds up in the area to heal and strengthen the wound[2]. This continues for several months, causing a raised or lumpy scar[2].
Many scars often start to look worse before they get better[3]. For about six weeks, you’ll notice the skin around your scar become very tight, hard and red as your body forms a strong scar[3]. Over the next four months, your scar should become smoother, softer and flatter[3].
