Hyaluronan or hyaluronic acid (HA) is a naturally present in the human body and plays a vital role in lubricating joints and in the proper functioning of connective tissues found in areas such as the heart valves, and the eyes.
It is also thought to be an anti aging substance and has been featured a lot in the media and scientific circles due to its potential role in the longevity of the residents of a village somewhere in Japan where the natural diet are known to stimulate the body to naturally produce adequate amounts of HA which sorts of counteract the decline in the body’s production as aging advances.
This substance, as a result, is now being used in anti aging products that claim to deal with a lot of aging issues, particularly skin aging issues, although there are valid concerns as to its efficacy when administered as a topical product (See related article about the Hyaluronic acid serum).
But what are the potential side effects of this substance?
HA is not a very well-studied substance right now but there are reports that indicate its potential side effects when administered via injection to treat joints with osteoarthritis.
While it is reported to be generally safe, it can sometimes cause irritation, redness and pain in the area where the substance is injected. When used in eye surgeries, it may cause increase in pressure inside the eyes. Allergic reaction is also considered a rare event. Injecting during pregnancy is also considered possibly safe. However, they do not allow use of HA if you plan on breastfeeding your baby.
Not much is known when administered as an oral supplement or as a topical application so it is best not to use any hyaluronic acid product during pregnancy.
To learn more, it is best to consult your doctor before using any anti aging product; most especially if you are pregnant or has other health issues.
