After the pencil is lodged in the skin, it is important to determine the depth of the pencil lodging and treat accordingly. 1. The pencil is lodged in the skin superficially: (1) If the pencil core is not broken inside the skin, the wound on the surface of the skin is still visible and the wound is still exposed, at this time, you can first use saline to rinse and then disinfect with iodine volts to try to remove all the residual pencil pigment in the skin to avoid staying in the body to cause hyperpigmentation and leave black marks on the body. (2) If the pencil core breaks off inside the skin, but the penetration is shallow, you can use tweezers to take out the pencil core and then repeat the above debridement operation. (2) If the pencil is stuck deeper into the skin: if the pencil core is stuck deeper into the skin, the skin wound is not visible, and only a small black spot can be seen on the surface, in this case, the local skin should be cut to remove the pencil core and then carry out thorough debridement and suturing. If there is a pencil into the skin, you should go to the hospital in a timely manner, by the doctor to diagnose the specific situation, according to the examination to develop targeted treatment.
