The sprayer streamlines the dosing of the substance contained in the ampoule and makes the application incredibly easy. Be sure to cleanse your skin before using an ampoule. USE: Open the ampoule with the ampoule opener as usual. Carefully insert the ampoule into the sprayer. Spray 1-2 times (or more as needed), about 30cm away from the face with your eyes closed. Ampoules should be consumed within a day. After that, remove the ampoule from the sprayer and rinse under hot water to clean it.
