Lacarrubba F, et al. – This research evaluated the efficacy of a novel aqueous solution containing nitric acid, zinc and copper salts, and organic acids (acetic, lactic, and oxalic acid) for the treatment of seborrheic keratoses (SK). Patients with complete clearance did not exhibit relapses at a 6–month follow–up (T2). Hence, this novel solution could serve as a promising alternative option for SKs, particularly in patients not keen or eligible to undergo invasive tissue–destructive procedures.
