Detailed answer

When you have cold sores, it is best to avoid using lip care products to prevent further irritation or the spread of the virus. Cold sores are caused by the herpes simplex virus, which is highly contagious. Using lip balms, lipsticks, or other lip care products can potentially aggravate the cold sores and make them worse. Additionally, sharing lip care products with others can increase the risk of transmitting the virus to someone else. It is important to allow the cold sores to heal naturally and avoid any product that may potentially worsen the condition or increase the risk of spreading the virus.
