Blephagel cools, cleans, refreshes and soothes eyelids. It is free from preservatives, parabens, alcohol and perfumes and so is suitable for most patients including those with sensitive skin. Innovative Steri-Free® technology means that Blephagel remains sterile for up to 2 months after opening. The inner aluminium layer ensures the tube remains airtight and a hermetic membrane protects against bacterial contamination.
