What is Hyaluronic Acid?

Hyaluronic acid, or hyaluronan, is a naturally occurring substance in the human body. It is a type of glycosaminoglycan, a key component of connective tissues, and acts as a cushion and lubricant in the joints and other areas of the body.

This versatile molecule can retain moisture, making it crucial for skin hydration and joint health. With its unique chemistry and physicochemical properties, hyaluronic acid is vital in maintaining overall skin health and resilience.

Chemistry and physicochemical properties

Hyaluronic acid is like a giant sponge in your body that holds onto water. It’s a long chain of sugars that our bodies make naturally, and it can be very stretchy and slippery, which helps keep your skin soft and your joints moving easily.

Scientists call this special sugar a high-molecular-weight polysaccharide because it has lots of parts linked together.

The weight of these chains matters a lot! When hyaluronic acid has a high molecular weight, it acts like a thick jelly and cushion joints or give skin a plump look. If the weight is lower, it’s more liquid-like and can go deeper into your skin to help heal wounds or make dry eyes feel better.

This magic stuff even changes how cells talk to each other based on size! So whether you put it on as cream, take supplements, or get an injection, the kind of hyaluronic acid you use makes a big difference in your health.

Tissue and cell distribution

Hyaluronic acid is a natural substance found all through the body. It’s really important for keeping tissues and cells healthy and working right. Most of it hangs out in the skin, eyes, and joints.

Special cells called mesenchymal make a lot of hyaluronic acid, but other cells pitch in too.

This gooey stuff plays a big role where it lives. Inside the layers of your skin, hyaluronic acid holds onto water like a sponge to keep things moist and plump. In your eyes, it helps everything stay clear so you can see well.

And in your joints, it works as a cushion so that they move smoothly without any pain.

Biosynthesis and degradation

Hyaluronic acid plays a major role in every part of the body. Cells make and break down this vital substance all the time. This process keeps skin moist, eyes lubricated, and joints moving smoothly.

Enzymes in the body help build hyaluronic acid by building its building blocks. These same enzymes can also take it apart when it’s old or damaged.

The balance between making and breaking down is crucial for health. If cells make too much, tissues might get too puffy. If they don’t make enough, dryness or stiffness can happen in the skin and joints.

Changes in this balance are linked with signs of aging, like wrinkles.

Some treatments use forms of hyaluronic acid that our bodies don’t break down as quickly. These long-lasting versions fill wrinkles or support healing in places like knees where cushioning has worn away.
