Core Viewpoint - The article discusses common misconceptions about facial cleansing and emphasizes the importance of proper cleansing methods for maintaining skin health [1] Misconceptions about Cleansing - Misconception 1: Deep cleansing is necessary for facial skin. In reality, the skin's surface does not require "deep cleansing," as the skin barrier only allows for the removal of surface dirt and oil [3] - Misconception 2: Amino acid cleansers must contain amino acids. The term "amino acid cleanser" should refer to those containing amino acid-based surfactants, not just any product labeled as such [10] - Misconception 3: More foam indicates better cleansing. The actual cleansing power depends on the formulation's surfactants, not the amount of foam produced [13] Identifying Cleansing Ingredients - To identify soap-based cleansers, look for fatty acids and strong alkalis in the ingredient list, such as sodium or potassium salts of fatty acids [4][5][6] - SLS (Sodium Lauryl Sulfate) and SLES (Sodium Laureth Sulfate) are strong surfactants that can lead to increased moisture loss and skin barrier damage, making them unsuitable for sensitive skin types [7][8] - Amino acid surfactants can be identified by their naming convention, typically including a fatty acid, an amino acid, and sodium or potassium [12] Recommended Cleansing Practices - According to the "Chinese Skin Cleansing Guidelines," it is recommended to cleanse the face twice daily, using appropriate products based on individual skin conditions [16] - The water temperature for cleansing should be warm to avoid damaging the skin barrier, and post-cleansing care should include moisturizers tailored to skin type [17]
