A manufacturing method of dressing which includes the following steps is provided. First, a bacterial cellulose film is provided, wherein the bacterial cellulose film includes cellulose and water. Then, the bacterial cellulose film is immersed in a glycerol solution and heated to greater than 100℃, such that the water of the bacterial cellulose film is replaced by the glycerol in the glycerol solution. Thereafter, a dialysis procedure is performed, wherein temperature of the dialysis procedure is less than the room temperature, so that the glycerol is distributed in the bacterial cellulose film with a concentration gradient.
