In the case of superficial facial tissues, the absorption of cosmetic sutures is usually about 1 week; in the case of superficial tissues of the lower extremities and feet, the absorption of cosmetic sutures usually takes about 2 weeks. Cosmetic thread is commonly known as sheep’s intestine thread, also known as fiber surgical suture, the absorption time of cosmetic thread is mainly related to the local postoperative healing, the depth of the suture and the suture site. The superficial tissues of the face have better blood circulation and absorb relatively quickly, usually about 1 week. Superficial tissues of the lower limbs and feet usually take about 2 weeks to absorb due to poorer local circulation. If there is a localized infection after the procedure, it will not be conducive to the absorption of the threads and the absorption time will be relatively longer. The use of cosmetic sutures does not mean that scars will not occur, the suture technique is more important than the suture itself, fine sutures can reduce most of the tension of the incision, which is more conducive to reducing the formation of scars.
