This paper describes a lip filling technique that administers hyaluronic acid using microcannulas. This technique considerably reduces the number of punctures compared to the conventional method, which uses needles. In addition, the microcannula’s blunt tip reduces the risks of intravascular injection of the substance and of disrupting key structures such as vessels and nerves. The results obtained by the authors confirm the less frequent occurrence of adverse effects and a high degree of physician and patient satisfaction.

We present a case of delayed-type hypersensitivity to hyaluronic acid (HA)-based filler on the face following the Pfizer booster in a Moderna-vaccinated individual. It is the first known case of treatment of the delayed-type hypersensitivity reaction with hyaluronidase following Covid vaccination. Hyaluronidase is a viable option to treat this reaction, particularly for patients who may not benefit from systemic treatment options. With an anticipated fourth round of vaccine boosters on the horizon, there may be an increased incidence of cutaneous adverse events, including the reaction discussed.
