Hyaluronidase is widely used in medical and cosmetic applications due to its ability to break down hyaluronic acid, a substance found in connective tissues. In medicine, it is often employed as an adjuvant to enhance the absorption and dispersion of other injected drugs, such as local anesthetics or fluids, by reducing tissue resistance. This makes procedures like subcutaneous fluid administration or ophthalmic surgeries more efficient. In cosmetic treatments, hyaluronidase is used to dissolve hyaluronic acid-based fillers, correcting overfilled areas or addressing complications like lumps or asymmetry. Additionally, it plays a role in fertility treatments by facilitating the penetration of sperm through the cumulus oophorus during in vitro fertilization (IVF). Its versatility in breaking down hyaluronic acid makes it a valuable tool in both therapeutic and aesthetic contexts.
