Which statement best describes emollients?

• A. Protect injured or exposed skin surface and permit healing
• B. Soften the skin or soothe irritation
• C. Reduce friction between surfaces
• D. Prevent moisture evaporation

Answer: (B)

Emollients are substances applied to the skin to soften and smooth it. Their primary action is to fill gaps between skin cells and support the lipid barrier, helping the skin feel less rough and irritated and improving comfort and hydration. That direct effect—softening the skin and soothing irritation—is why this description is the best fit. Some emollients also form a barrier that reduces water loss from the skin, but that is a secondary effect and not the defining description. Choices that emphasize protecting injured skin or merely reducing friction don’t capture the main purpose of emollients as clearly.
