Yellowing of cold sores at the corners of the mouth may indicate improvement. Cold sores at the mouth corners primarily refer to herpes simplex lesions on the lips. Yellow discoloration typically occurs as the blisters dry out and secretions gradually crust over, forming pale-yellow crusts. At this stage, no new vesicles will appear. However, proper local care remains essential—keep the area clean and hygienic.
