HEALTH BENEFITS OF HYALURONIC ACID include:
Anti-ageing/hair follicles, nourishing deep layers of the scalp/skin ageing/scars/bones and cartilage/atopic dermatitis/eyes/gum disease/anti-oxidant
Hyaluronic Acid in Bones and Cartilage
Both of these structures provide a resilient rigidity to the structure of the human body. HA is especially found in various forms of cartilage but none more than the hyaline cartilage. As you've probably guessed it, hyaline is short for hyaluronic acid. Hyaline cartilage covers the ends of the long bones where articulation (bending) occurs and provides a cushioning effect for the bones. The hyaline cartilage has been called the "gristle cartilage" because its resistance to wear and tear. Hyaline cartilage also supports the tip of the nose, connects the ribs to the sternum and forms most of the larynx and supporting cartilage of the trachea and bronchial tubes in the lungs.
Hyaluronic Acid in Synovial fluid
Our joints (like the elbows and knees) are surrounded by a membrane called the synovial membrane which forms a capsule around the ends of the two articulating bones. This membrane secretes a liquid called the synovial fluid. Synovial fluid is a viscous fluid with the consistency of motor oil. It has many functions, but none more than providing the elastic shock absorbing properties of the joint. Its second most important function in the joint is to carry nutrients to the cartilage and to also remove waste from the joint capsule.
Hyaluronic Acid in Tendons and Ligaments/Connective tissue
Connective tissue is found everywhere in the body. It does much more than connect body parts; it has many forms and functions. Its major functions include binding, support, protection, and insulation. One such example of connective tissue is the cordlike structures that connect muscle to bone (tendons) and bone to bone (ligaments). In all connective tissue there are three structural elements. They are ground substance (hyaluronic acid), stretchy fibers (collagen and elastin) and a fundamental cell type. Whereas all other primary tissues in the body are composed mainly of living cells, connective tissues are composed largely of a nonliving ground substance, the hyaluronic acid, which separates and cushions the living cells of the connective tissue. The separation and cushioning allow the tissue to bear weight, withstand great tension and endure abuse that no other body tissue could. All of this is made possible because of the presence of the HA and its ability to form the gelatinous ground substance fluid.
Hyaluronic Acid in Scalp Tissue and Hair Follicles
Structurally the scalp is identical to the skin tissue located throughout the body except it also contains about 100,000 hair follicles that give rise to hair. Actually the hair and the hair follicle are a derivative of skin tissue. There are two distinctive skin layers, one, the epidermis (outer layer) which gives rise to the protective shield of the body and the other, the dermal layer (deep layer) which makes up the bulk of the skin and is where the hair follicle is located. This dermal layer is composed of connective tissue and the connective tissue, with its gelatinous fluid like characteristics provides support, nourishes and hydrates the deep layers of the scalp. The result is healthy lustrous hair and a moisturized scalp. Again, all of this is made possible because of the presence of HA in the scalp.
Hyaluronic Acid in the skin
The skin is the largest organ in the body comprising about 15% of the body weight. Roughly 50% of the Hyaluronic Acid in our body is found in the skin. HA and Collagen are vital to maintaining the skin’s layers and structure. It is the collagen that gives the skin its firmness but it is the HA that nourishes and hydrates the collagen. Imagine the collagen as the stretchy fibers that restore the skin back to shape when stretched. Collagen is like a rubber band but stretch that rubber band a million times, like what we do with our skin and without any moisture. Eventually that rubber band gets overstretched (saggy) and dried out and will most likely break. This is much the same way the collagen in our skin reacts leaving our skin in need of moisture. Now imagine that same rubber band stretched a million times while under water the whole time. Chances of that rubber band drying out and breaking are minimal. Consider the Hyaluronic Acid as the water that keeps the collagen moist and elastic. Collagen is continuously surrounded and nourished by the gelatinous HA substance. Young skin is smooth and highly elastic because it contains high concentrations of Hyaluronic Acid, which helps skin stay healthy. As we grow older, the body loses its ability to maintain this same concentration in the skin. With decreasing levels of HA in the skin, so goes the ability of the skin to hold water. The result, the skin becomes drier and loses its ability to maintain it's hydration. Hyaluronic acid acts as a space filler by binding to water and thus keeping the skin wrinkle-free.
