Earex Advance Ear Drops has a dual action formula which softens and removes hard earwax. Used regularly, Earex Advance Ear Drops can also prevent the build up of hardened earwax and reduce the need for syringing. The dual-action formula contains glycerin to gently soften earwax and urea peroxide which releases oxygen to break up and disperse hardened earwax deposits - helping to reduce the need for syringing. The bottle is soft and squeezable to help control the number of drops dispensed for further convenience.
