The scabs may not fall off because it is not time for the scabs to fall off, or it may be due to poor healing caused by not taking good care of the piercing port, etc. After the procedure, the scabs usually stabilize in about 3~5 days. After thread sculpture surgery usually about 3~5 days will be stabilized scabs, in 10~14 days scabs will gradually fall off. If the thread sculpture puncture opening is large or the incision is delayed due to the protein thread stimulation at the incision, the time needed for the scabs to fall off may be a little longer. Failure of the scabs to fall off properly does not rule out infection of the puncture opening, which can also affect the healing and eventual time for the scabs to fall off. It is recommended that patients change the medication regularly after the operation, take care of the puncture opening as prescribed, and observe the wound site closely. If the scab does not fall off for a long time or if there are any abnormalities such as redness, swelling, heat and pain, they should go to a regular medical institution immediately in order to avoid any adverse consequences.
