Hyaluronan

Meaning

Hyaluronan, also known as hyaluronic acid, is a high-molecular-weight glycosaminoglycan, a linear polysaccharide that is a principal component of the extracellular matrix throughout the human body. It is renowned for its exceptional capacity to bind and retain water molecules, which provides structural integrity, hydration, and turgor to the skin, and acts as a lubricating and shock-absorbing component in synovial fluid and cartilage. Its concentration in dermal tissue is a major determinant of skin youthfulness and elasticity.
