A method and/or composition for monitoring electrical signals from a patient through a biomedical electrode or delivering an effective amount of electrical stimulation to said patient without causing erythema which comprises providing an antioxidant to the skin of said patient via solution, lotion, or gel prior to adhering said biomedical electrode thereto or incorporating in the hydrogel conductive adhesive of the electrode for antioxidant activity during electrical contact. Chemical precursors of some antioxidants are utilized for the manufacture and stable incorporation into hydrogel conductive adhesives to avoid interference with the preparation of the conductive adhesive by free radical polymerization.
