Surgical scars cannot be completely eliminated because the scars left on the skin after surgery are a protection of the body during self-healing and cannot be completely eliminated at present. The scars left after surgery are difficult to return to the original skin state, and when you touch them with your hands, you can clearly feel that the skin at the scar site is not the same as the original skin. Normal skin is composed of epidermis, dermis and subcutaneous tissues, but scars are often formed by hard and proliferating connective tissues, which can only be made less visible through existing technology, but it is impossible to completely eliminate them and make them look like normal skin. It is recommended to choose cosmetic sutures after surgery, and with the use of cosmetic patches, the scars of the wounds are usually not too obvious. Since surgical scars are more difficult to remove, it is important to take care of the wound after surgery and to restore your wound to the best condition possible.
