super easy to use and stuck to my face no problem. I had a pimple that was close but not ready to pop so i used a star on it. the next morning it was ready to be popped easily. used another star on the spot after popping and cleaning it. besides some redness that spot was basically gone and i just needed it to heal up. I really like the packaging of this. super easy to use and there is a mirror to make it easier for on the go if needed. i was able to just sit in bed and apply the star wherever needed. also i cant wait to throw in other refills that i bought and use this compact to hold it all when i travel.
