The brown marks left behind after medicated mole spotting can usually be eliminated, but due to individual differences, there are some people whose brown marks will only become lighter. Mole spotting is the use of drugs such as trichloroacetic acid to remove moles by corroding the local skin. Usually, the brown marks left behind after the medicated mole spotting can be eliminated. However, as each person’s situation is different, if the mole is large in size or if you do not take proper protective measures after water spotting, the brown marks left behind may only become lighter in color. It is important to protect yourself from the sun and eat a light diet after the procedure, and it is recommended that you go to a regular hospital for advice. If the brown marks left behind after the medicated mole spotting have not been eliminated, you should go to a regular hospital for consultation to clarify the cause.
