Detailed answer

Melasma is a condition characterized by dark patches on the skin, usually on the face. It is caused by an overproduction of melanin. Cold sores, on the other hand, are caused by the herpes simplex virus. While both conditions can occur on the same person, there is no direct connection between melasma patches and cold sores. Cold sores are typically triggered by factors such as stress, illness, or exposure to sunlight. Therefore, it is not accurate to say that melasma patches make a person more prone to cold sores. It is important to take care of the skin by using sunscreen, avoiding triggers, and managing stress to prevent cold sores and minimize the appearance of melasma patches.
