Bioavailability
Bioavailability is a key concept in cosmetics that describes how well a product's ingredients can be absorbed and used by the skin or body. Think of it like how effectively a plant can absorb water - some forms of water are easier for the plant to use than others. In cosmetics, making ingredients more bioavailable means ensuring they can actually deliver their promised benefits rather than just sitting on the surface. When reading resumes or job descriptions, you might see this term used when candidates talk about improving product effectiveness or developing better delivery systems for skincare ingredients.
