Abstract
Benign pigmented lesions are among the most common dermatologic diagnoses that patients seek treatments for. Treatment modalities range from cryotherapy to light and laser-based technologies. These treatments have been shown to be effective, yet may lead to dyschromia or significant downtime. Therefore, we report the first clinical experience with a novel Dermal Cooling System that provides localized and controlled freezing to benign pigmented lesions. Twenty patients seeking treatment for benign pigmented lesions were treated with the Dermal Cooling System at the laser and cosmetic dermatology clinic at the University of California, San Diego. Photographs were captured at baseline and follow-up visits. Two blinded investigators reviewed and graded the photographs. Most patients experienced improvement after 1 month following the first treatment. Macular or slightly raised lesions responded best. Treatment side effects were transient, lasted a maximum of 3 days, and included erythema, swelling, itching, and darkening. There was no observed long-term dyschromia. The novel Dermal Cooling System shows promise in the treatment of flat to slightly raised benign pigmented lesions with little-to-no downtime. Further clinical experience is necessary to continue to optimize treatment parameters. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.
