Which skin type is most likely to benefit from moisturizers that help retain moisture?

• A. Dry skin
• B. Oily skin
• C. Aging skin
• D. Combination skin

Answer: (A)

Moisturizers that help retain moisture are most beneficial for dry skin because its barrier is often compromised and water loss is higher. These products work by attracting water into the skin with humectants (like glycerin or hyaluronic acid) and by forming a protective layer on the surface to seal in that moisture with occlusives (like petrolatum or dimethicone). The result is better hydration, smoother texture, and less flakiness where the skin is naturally drier.

Oily skin tends to respond better to lighter, non-occlusive hydrators that don’t feel heavy or greasy, and aging skin can be dry as well but dry skin is the classic case that clearly benefits from moisture-retaining formulas.
