Hyaluronidase in Dermatology: Uses Beyond Hyaluronic Acid Fillers.

Hyaluronidase is mostly widely recognized for its off-label use in correction of complications of hyaluronic acid fillers. However, its utility in other aspects of dermatology is less widely acknowledged. We describe the varied uses of hyaluronidase in dermatology and the underlying evidence base for its dermatological indications. This includes its uses in enhancing drug delivery (for local anesthesia, keloid and hypertrophic scars, and for Kaposi’s sarcoma), in the treatment of disorders associated with mucin deposition (myxedema, scleroderma, scleredema, and cutis verticis gyrata) and its potential uses in surgery (as a pre-operative adjuvant in dermatofibrosarcoma protuberans, for periorbital edema, and for hematomas). In select circumstances, hyaluronidase might be more efficacious than more established treatments with fewer adverse effects. We propose hyaluronidase as the latest addition to our global dermatological armamentarium and implore dermatologists to consider its use to enhance their practice.
