Clinical Experience With 40% Hydrogen Peroxide Topical Solution for the Treatment of Seborrheic Keratosis.

Despite reassurances about the benign nature of seborrheic keratoses (SKs), patients often request treatment due to cosmetic concerns or for symptomatic relief when SKs become irritated or pruritic. Treatment options include cryotherapy, surgical techniques, and topical therapies. In this study, we present two patients with SKs located on their face and neck who received in-office treatment with 40% Hydrogen Peroxide Topical Solution (Eskata™, HP40), a new FDA-approved topical therapy that has demonstrated efficacy in phase 3 trials. Compared to non-topical, more invasive techniques, HP40 may lead to less pigmentary changes, and may be more efficacious for SKs on the face and neck. Both patients received two treatment courses of HP40, which resulted in positive therapeutic outcomes, including the absence of scarring and pigmentary changes. In addition to the case presentations, we will discuss considerations for appropriate administration of HP40 to maximize clinical outcomes. J Drugs Dermatol. 2019;18(7 Suppl):s173-177.
