Detailed answer

Exfoliating involves the removal of dead skin cells from the surface of the skin. Cold sores, also known as fever blisters, are caused by the herpes simplex virus and are highly contagious. Exfoliating a cold sore can lead to further irritation and potentially spread the virus to other areas of the skin. It is crucial to allow the cold sore to heal on its own and avoid any physical manipulation of the area. Instead, focus on keeping the cold sore clean and moisturized to promote healing. If you have concerns or need further guidance, it is best to consult with a dermatologist or healthcare professional.
