humectant
This term is primarily used in technical, dermatological, and food science contexts to describe agents that attract water from the air or deeper layers of the skin. It carries a clinical and functional connotation, focusing on the chemical ability to bind moisture rather than the general feeling of being moisturized.
In a commercial context, it is frequently found on ingredient lists for skincare and pharmaceuticals. While a moisturizer might be a broad category of product, a humectant is the specific active ingredient responsible for the hygroscopic effect.
