Emollients are comprised of which type of molecules?

• A. Lipids
• B. Proteins
• C. Carbohydrates
• D. Nucleic acids

Answer: (A)

Emollients work primarily because they are lipid-based molecules that form an occlusive film on the skin. This lipid layer smooths and lubricates the surface, helps restore the skin’s natural barrier, and reduces water loss. Lipids include components like triglycerides, fatty acids, ceramides, cholesterol esters, and related oily substances that coat the skin and fill in gaps between cells. While proteins and carbohydrates are important for skin structure and function, they aren’t the main constituents of typical emollients, and nucleic acids aren’t involved in moisturization. So the best description is that emollients are composed of lipids.
