Collagen is known for its ability to make our skin smooth, supple, and elastic. But what other words can we use to describe this essential protein that is responsible for so many of our bodily functions? Some synonyms for "collagenic" include connective tissue, fibrous tissue, and proteinaceous substance. Another option is to use the term "dermal," which specifically refers to the layer of skin that contains collagen. Other related terms include elastin, which is another protein that helps give skin its elasticity, and hyaluronic acid, which is a substance found in connective tissue that helps keep skin hydrated. By using these different synonyms, we can better describe the many functions and properties of collagen in the body.
