Although scientists have yet to demonstrate explicitly that these substances cause harm, insufficient evidence supports their use, and the long-term effects are unknown. Even safe antiseptics, such as isopropyl alcohol, can promote cytotoxicity in the wound over time, eroding good cells and slowing healing, according to recent research. Because of their potency, specialists only advocate using antiseptics when required or when there is a genuine risk of infection.
