Hyaluronidase is widely used in medical and cosmetic fields due to its ability to break down hyaluronic acid. In medicine, it is employed to enhance the absorption and dispersion of injected drugs, such as local anesthetics, improving their effectiveness and reducing discomfort. It is also used in ophthalmic surgeries to facilitate the spread of anesthesia and in treatments for conditions like hyaluronidase deficiency or to reverse the effects of hyaluronic acid fillers in case of complications. In cosmetic procedures, it helps dissolve hyaluronic acid-based dermal fillers, allowing for adjustments or corrections. Additionally, it aids in subcutaneous fluid administration by improving the absorption of fluids in cases of dehydration or hypodermoclysis.
