Facial cleanser, also known as face wash or cleanser, is a skincare product used to cleanse facial skin. Its main function is to remove dirt, excess oil, and makeup residue from the skin's surface. Commercially available products are mainly divided into amino acid-based and soap-based types based on their core cleansing agents. The former is gentle and skin-friendly, while the latter has stronger cleansing power.
When choosing a cleanser, it's essential to consider your individual skin type. For example, oily skin types should choose oil-controlling cleansers, while dry and sensitive skin types should use moisturizing and repairing cleansers. It's generally recommended to use it 1-2 times daily to avoid over-cleansing and damaging the skin barrier. High-quality products are usually slightly acidic, better suited to the skin's natural environment, and should be moisturized promptly after use.
