In my recent research on effective treatments for corns and calluses, I discovered the impressive role of benzalkonium chloride and zinc oxide. These two active ingredients have shown promising results in not only soothing the discomfort but also promoting the healing process. Benzalkonium chloride acts as an antiseptic, reducing the risk of infection, while zinc oxide provides a protective barrier on the skin. Together, they create a powerful combination that helps to soften and break down the tough skin associated with corns and calluses. If you're struggling with these pesky skin issues, you might want to consider giving benzalkonium chloride/zinc oxide a try!
