What qualities should a skin cleanser possess?

A skin cleanser should effectively cleanse the skin while ensuring that it does not cause irritation. This is crucial because the primary function of a cleanser is to remove dirt, oil, makeup, and impurities from the skin's surface. If a cleanser is harsh or irritating, it can disrupt the skin barrier, leading to issues such as redness, dryness, or breakouts. A good cleanser should maintain the skin's hydration levels and pH balance while doing its job, which is why a gentle formulation is often recommended.

In contrast, while hydration is beneficial and desirable in skin products, deeply hydrating is not a primary characteristic of a cleanser; rather, this property is typically associated with moisturizers. As for scent, while many people may enjoy a scented cleanser, it is not a quality that is essential for effective cleansing and can sometimes cause irritation, particularly for sensitive skin. Lastly, cleansing should promote long-term skin health rather than focusing on instant results, which can be misleading, as proper cleansing contributes to the overall condition of the skin over time.
