The source of a scar results in the span of time it is necessary to wait to have laser scar treatment following the scar's development. For instance, if it originates from an invasive clinical procedure, it is usually safe to perform laser scar treatment after only a few weeks of the sutures being removed, which gives time for the opening to heal fully. Acne scars, though, may be treated with laser therapy once the responsible acne condition is under control.
