How small does a scar have to be to get stitches to remove the scar?

Stitches are typically used for wounds that are deep or large enough to require closure to promote healing and minimize scarring. Generally, if a scar is less than a few millimeters wide and not deep, it may not require stitches. Instead, smaller wounds can often heal well on their own or with adhesive strips or topical treatments. It's best to consult a healthcare professional for specific recommendations based on the scar's size and location.
