the cannula's 18 gauge tip was pointed upward and approximately parallel to the skin's surface when it was put into the superficial dermis, 1-2 millimeters away from the targeted scar. In order to completely remove fibrous tissue from the superficial dermis, a lancing motion (linear inserting-withdrawing needle action) was utilized first.
