Hyaluronic Acid Fillers

    Hyaluronic Acid fillers (HAs)

    The most common fillers used today are in the group known as hyaluronic acid, or HA products.

    In 1934, medical researchers Karl Meyer and John Palmer, scientists at Columbia University, found that one of the chief functions of hyaluronic acid is maintaining skin volume and hydration, along with other body maintenance functions and tasks. Hyaluronic acid later found uses in the baking and food industry in the 1940s and, by the 1990s, found its way into the medical field for use in joint pain, treating wounds, ye surgery and, finally, in 1996, for facial tissue augmentation in Europe.

    These fillers work well because hyaluronic acid can absorb up to 1,000 times its own weight in water, thereby adding new volume under the surface of sagging skin. Older faces take on a more youthful appearance because hyaluronic acid is known to bind with collagen, the material that supports human facial skin, and elastin to move more basic nutrients into the skin.

    All hyaluronic acid filler products are eventually absorbed by the body, usually within six to ten months, necessitating the patient to return for repeat injections to maintain the effects. HA products are also used by physicians to augment lips. HA’s are the preferred choice for first time patients as their results are predictable, they are well tolerated and are the only filler that can be reversed if necessary with the use of an enzyme called hyaluronidase.

    None of the products have been tested in or approved for use in pregnant females, lactating females or children. Due to this it is generally accepted that none of the injectables should be used in patients that fall into these catagories.
