The gentle, petrolatum-based ointment provides instant, continuous protection against a broad spectrum of harmful fungi, bacteria, and viruses – including influenza, MRSA, staph, and many other infectious viruses.
Applied 2-3 times a day in the nose, a common entry point for many infectious organisms, Certainty SmartShield traps and kills airborne pathogens, helping reduce the risk of getting or spreading an infection.
Harsh on pathogens,
gentle on you.
Certainty SmartShield’s innovative extended-release formula delivers potent medication in a petrolatum-based ointment, similar to petroleum jelly.
It’s more effective than liquid antiseptics (like iodine or alcohol) at stopping staph, MRSA, and human coronaviruses , but extremely gentle – even on open wounds and nasal passages
A little dab starts working in seconds, without irritation or tissue damage. The petrolatum in the ointment works as a barrier, physically trapping pathogens that lead to infection and illness. The extended-release antiseptic ingredients work to eradicate organisms and help prevent them from replicating, providing protection that lasts for hours.
A 2020 study using human coronavirus showed Certainty SmartShield reduces viral load by 98% within two hours after application with zero damage to healthy cells.
