How it works
Zymox’s LP3 Enzyme System supports the ear’s natural defenses by breaking down microbial structures associated with common ear problems in pets. PLUS Otic adds additional enzymes aimed at disrupting biofilm, helping the solution reach and work on hard-to-address ear gunk. The 1% hydrocortisone provides targeted relief for redness and itch.
