On whether a cleansing product contains glycolic acid
Some people suspect that a cleansing product (Cetaphil) contains glycolic acid. Glycolic acid has attracted much attention in the skin care industry because of its unique effects, but it also has skin discomfort. Therefore, it is of great significance to explore the presence or absence of glycolic acid in this product.

To determine whether a product contains glycolic acid, it is first necessary to review its ingredient list in detail. Many products will clearly list the ingredients contained in the ingredient list. If this product has the words "Glycolic Acid" in the ingredient list, it can be proved that it contains glycolic acid.

Furthermore, you can find the test report of a professional organization. Professional testing institutions can accurately determine whether the product contains glycolic acid and the content geometry with accurate instruments and scientific methods. The results obtained from this approach are more authoritative and reliable.

In addition, it is also a method to refer to the feedback of users. If many users have reactions related to the characteristics of glycolic acid after use, such as some sensitive skin people feel tingling and redness after use, and this reaction is consistent with the irritation reaction that glycolic acid may cause, it may suggest that the product contains glycolic acid. However, user feedback is greatly affected by individual differences and can only be used as a reference and cannot be fully trusted.

To sum up, in order to determine whether Cetaphil contains glycolic acid, it is necessary to explore through multiple channels, synthesize the ingredient list, test report and user feedback, etc., in order to reach a more accurate conclusion.
