“it works in terms of whitening but the effect wears out fairly quickly (so it's good if you have an event or you want a quick touch up)
also and differently from other stripes, they melt in your mouth but as you close your lips they stick a bit everywhere”
“Good idea, terrible execution.
Strips are invisible, yes, but they are also extremely sticky and because of this, the strips stick to your inner lips, gums after you put them on. Basically anywhere but your teeth.
Used on two nights. Gave up after.
Disappointed - especially since I really like Zenyum brushes!”
