What is the primary function of a cleanser in a skincare routine?

• A. Removes natural moisturizing factors
• B. Cleanses without removing natural moisturizing factors
• C. Exfoliates the skin
• D. Provides long-lasting hydration

Answer: (B)

The main idea is that a cleanser is meant to clean without stripping the skin’s moisture. It should remove dirt, oil, makeup, and impurities from the surface while keeping the skin’s natural moisturizing factors intact. Those factors help the stratum corneum hold onto water, so preserving them supports the skin’s barrier and prevents excess dryness. Gentle cleansers use mild surfactants and a balanced pH to achieve cleansing without removing what the skin needs to stay hydrated. Exfoliation is a separate function performed by exfoliants, not the cleanser’s primary role. Hydration beyond basic cleansing comes mainly from moisturizers and humectants applied after cleansing, not from the cleanser itself.
