As a wound heals scar tissue fills in the damaged places. While a scar may look quite dramatic after itâs first formed, over time its appearance, size and color naturally fade. On average, most scars can take 6 to 18 months to heal naturally. More severe scars can take years.
Most scrapes heal well with home treatment and do not scar. Minor scrapes may be uncomfortable, but they usually heal within 3 to 7 days. The larger and deeper the scrape, the longer it will take to heal. A large, deep scrape may take up to 1 to 2 weeks or longer to heal. It's common to have small amounts of fluid drain or ooze from a scrape.
