On the relationship between glycolic acid and cold sores
There are people who doubt that glycolic acid can cause cold sores, and this argument needs to be investigated in detail. Glycolic acid is more common in many skin care products, and it is important for people because of its skin rejuvenation equivalent.

However, the birth of cold sores is mostly caused by the herpes simplex virus. This virus is often lurking in the human body, and it can only cause cold sores when the body's immunity changes, such as fatigue, chills, emotional fluctuations, etc.

Or some people say that cold sores appear after using something containing glycolic acid, but this is not necessarily a cause and effect. When covering skin care, or due to other factors, immune changes are caused, causing virus activation, rather than glycolic acid directly. And the population has different constitutions, different tolerance to glycolic acid, or sensitive people who have abnormal skin conditions after use, but it is difficult to determine that it must be related to cold sores.

To determine the relationship between glycolic acid and cold sores, rigorous scientific methods should be used. A wide range of samples were collected, and glycolic acid was divided into those who did not use it, and the frequency and degree of cold sores were carefully observed. And the experiment should control other causes, and keep the environment and living habits similar. If repeated studies were conducted, the incidence of cold sores in those who used glycolic acid was significantly higher than that in those who did not use it, it could be said that there may be a correlation; otherwise, it is only an occasional phenomenon, and it is not a scientific way.

In summary, based on limited knowledge, it is difficult to determine that glycolic acid is indeed related to cold sores. It is necessary to conduct in-depth scientific research and prove it with evidence before we can obtain a correct solution, so that everyone can have a correct understanding of skin care and herpes prevention.
