The benefits of hyaluronic acid are many and it is a natural substance that we can find in many parts of our body. An example? The fluids of our eyes and joints. It works in part as a "shock absorber" but also as a lubricant for joints and other tissues. 

Furthermore, different variants of hyaluronic acid are used in the field of aesthetics and cosmetics. But also medicine, since hyaluronic acid has a regenerating effect on tissues and tends to reduce swelling.

Hyaluronic acid injections are approved by scientific committees for a variety of uses. These include cataracts, osteoarthritis, but also the treatment of facial wrinkles. People also tend to take hyaluronic acid via supplements, or apply it to the skin in the form of a serum to fight aging. But its effects don't stop there, because hyaluronic acid also works well in contrasting pathologies such as gastroesophageal reflux. There are various benefits.

How hyaluronic acid works: the fields in which it is most effective

Hyaluronic acid has proven its effectiveness in several areas. Primarily, in the treatment of cataracts by injection into the eye during eye surgery. Furthermore, it reduces swelling and inflammation of the oral cavity mucosa, where it is taken in the form of a gel. But that's not all, because hyaluronic acid is widely used in cosmetics and aesthetic medicine, where its injections into facial wrinkles reduce facial wrinkles (or eliminate them, if they are superficial) for over a year. However, it is not clear whether the same effect is also obtained by taking supplements, or by applying specific creams to the face. 

Another very common use is to use it in drops to reduce dry eyes. And, as we said, to inject it into the joints to reduce the effects of osteoarthritis, reducing pain and soreness. Again, it's unclear whether similar results are achieved by taking supplements.

Side effects of hyaluronic acid: do they exist? And what are they?

The side effects of hyaluronic acid exist – even if they are few – and depend on the way it is taken. For example, taken in supplement form it tends to be very safe, although there have been rare reports of allergic reactions. The same can be said when taking acid with creams or serums. However, there are not enough studies to determine its effects during pregnancy and breastfeeding, therefore its use is not recommended in those cases for complete safety. It is also unknown if it is transmitted with milk.

In case of scleroderma of the skin or connective tissue, the application of hyaluronic acid can cause ulcers, therefore its use is also not recommended in this case. There is also not enough information about his interactions.

How much hyaluronic acid to take? The dosage

Hyaluronic acid injections are recommended for various pathologies, but performed by healthcare personnel. Hyaluronic acid is also available in several topical products, including creams, gels, mouthwashes, and eye drops. In supplements, there are no reliable sources on appropriate doses. In general, it must be borne in mind that the dosage is important, therefore it is advisable to follow the instructions of the medical staff or, in the case of supplements, the package leaflet.
