Which of the following is an important step in skin cleansing?

Properly removing all make-up is a crucial step in skin cleansing because it ensures that the skin is free from impurities, pollutants, and cosmetics that can clog pores and lead to various skin issues such as acne, irritation, and premature aging. When make-up is not thoroughly removed, residual products can interfere with the skin's natural functions and inhibit the efficacy of subsequent skincare treatments.

Effective cleansing involves not just removing visible dirt but also eliminating all traces of make-up to allow the skin to breathe and regenerate. Following this practice helps in achieving a clear and healthy complexion, setting the foundation for other skincare rituals such as toning and moisturizing.

Other options present less critical or incorrect approaches to skin cleansing. For instance, neglecting product selection may lead to using inappropriate or harsh products that can damage the skin. While quality moisturizers are essential for hydrating the skin, their application is not part of the cleansing process itself. Massaging with oil can be beneficial, but it does not take the place of properly removing make-up and impurities from the skin's surface.
