Ferric Subsulfate, Aqueous, is a stypic agent used for achieving local hemostasis. In punch biopsies of the full dermis, the time to achieve hemostasis is typically less than 20 seconds. 1 One method of applying ferric subsulfate solution for dermal use consists of the physician placing fingers at the opposite edge of the wound and stretching the skin. The wound is then wiped with gauze, the ferric subsulfate solution applied, and the tension maintained for approximately 15 seconds. 2
