How to open a Dr. Temt ampoule?

A white ring can be found in the neck of the ampoule, which is the breaking point. Make sure you’re holding the ampoule upright, if there is liquid above the neck gently tap with your finger to get all the liquid to the bottom part of the ampoule. Hold the ampoule with both hands, hold the bottom of the ampoule firmly. Next protect your hands from broken glass by using a tissue, gauze, or towel when opening the ampoule, place this around the neck of the ampoule with one thumb against it, away from you and with light even pressure snap it open. The ampoule is ready to be used.
