NO PRESERVATIVES OR PHOSPHATES
Preservatives are chemical substances used to guarantee the sterility of the product during its time of use. Preservatives are products capable of destroying or inhibiting the growth of microorganisms, and despite their use at very low concentrations, they cause cellular toxicity. Occasionally, they can damage the cells of the ocular surface, cause instability in the tear film, and reduce the tear breakup time. This effect is just the opposite of what you want to achieve with the application of artificial tears.
In MONOFRESH, thanks to the container in the form of a single dose it is not necessary to use preservatives, since its instantaneous use for later discarding the open unit does not require its presence.
