Small wounds closed with 0-gauge sutures usually leave scars, and for some of those who do not have a significant reaction to the sutures, the scars may be inconspicuous. For sutured wounds, scars are usually left after suture removal, mainly due to traumatic injuries, usually to the deep dermal layer of the skin, and scarring occurs due to the misalignment of the fibrous tissue during healing. Regardless of the thickness of the suture, when performing wound closure, it is also possible to leave a thread scar after suture removal. The thinner the suture, the less noticeable the scar will be. However, for those who are allergic or have a significant reaction to sutures, a thicker 0-gauge thread will result in more visible scarring after removal of the suture, and in severe cases, the scar tissue will be significantly higher than the surface of the skin. Therefore, the scars left behind by small wounds are generally affected by the wound surface on the one hand, and the thickness of the sutures on the other.
