Hyaluronan: What is it?

Info Hyaluronic Acid
Hyaluronic acid is a fluid that is produced naturally by our body. Hyaluronic acid (HA) is the key molecule involved in keeping the skin moisturized. It has become a key component in many Anti-aging products! Hyaluronic acid has the ability to retain over 1,000 times its weight in water within the cells of the skin.

HA belongs to the extracellular matrix (ECM) molecules. These are the spaces between cells. The predominant component of the skin ECM is HA (Hyaluronic Acid).

Skin aging is also associated with loss of skin moisture. Human skin aging is a complex biological process. An unpreventable process, which affects the skin in the same pattern as it affects all internal organs is aging. Secondly, the result of exposure to external factors, mainly ultraviolet (UV) irradiation, that is also referred to as photoaging.

In humans, HA is most abundant in the skin, accounting for 50% of the total body, the vitreous of the eye (a gel-like substance that helps the eye maintain a round shape), the umbilical cord, and synovial fluid (fluid found in the cavities of joints), but it is also present in all tissues and fluids of the body, such as skeletal tissues, heart valves, the lung, the aorta, the prostate, etc…

As you can see, Hyaluronic Acid is a very important fluid that is needed by our body.

Layers of the skinThe HA content of the dermis is significantly higher than that of the epidermis, while papillary dermis has much greater levels of HA than reticular dermis.

Functions of HA include the following: hydration, lubrication of joints, a space-filling capacity, and the framework through which cells migrate. HA regulates several aspects of tissue repair, including activation of inflammatory cells to enhance immune response and the response to injury of fibroblasts (Fibroblasts are the most common cells in connective tissue. Their main function is to maintain the structural integrity of the connective tissue by continuously secreting extracellular matrix proteins) and epithelial cells. Epithelial cells are a type of cell that lines the surfaces of your body.

Present in every tissue, it performs many important functions. HA helps deliver nutrients to cells and carry toxins from cells that do not have a blood supply, such as those found in cartilage. HA not only keeps the cartilage that cushions joints strong and flexible but also helps increase supplies of joint-lubricating synovial fluid. Without adequate amounts of HA, the joints will become brittle and deteriorate.

Premature aging of skin is the result of repeated and extended exposure to UV radiation. Approximately 80% of facial skin aging is attributed to UV-exposure. UV radiation skin damage is an extremely rapid event. Skin unprotected from the exposure to the sun by damaging UV rays can cause premature aging. Ultraviolet radiation from the sun can cause skin cells to reduce their production of hyaluronic acid.

Passage of time and repeated exposure to harmful aspects of the environment alter both the epidermal and dermal compartments of the skin. Clinically, chronologically aged skin appears thin, dry, and finely wrinkled. The photoaged skin typically appears leathery, lax, with coarse wrinkles, “broken”-appearing blood vessels (telangiectasia), and uneven pigmentation with brown spots.

Wrinkles and fine lines are initially caused by facial expressions, but starting as early as the age of 20, the body produces one percent less of collagen in the dermis layer every year. By the age of 40, these lines deepen, while eyes and cheeks appear hollower and jowls develop because about 50% of all the HA in the body is located in both the epidermal and subcutaneous skin layers. Above 55 to 60, all the visible aging effects become even more pronounced.

Hyaluronic Acid Serum is a popular choice for boosting HA levels as it can attract moisture to the skin from within the body. However, we recommended that you thoroughly apply the serum until fully absorbed and then seal it in with a moisturizer. This is because Hyaluronic acid if left to sit on the skin, can actually pull moisture out of the skin altogether!

Well-hydrated skin is necessary to reinforce the epidermis and its hydrolipidic barrier, which functions as a shield over the skin: retaining moisture and protecting against bacteria.
