Still not close
I use the sample for and then I bought a 12 pack and I've been using the 12 and I still don't see much difference.. I don't know how long this takes but I'm not quite impressed yet
Hi there, Joanne!
Thanks so much for the review. I'm so sorry to hear you haven't noticed much of a difference after using the whitening strips! They work to whiten teeth through prolonged exposure to hydrogen peroxide, so we recommend leaving them on for a full 30 minutes. For best results, we typically recommend starting with 12 consecutive treatments and then one treatment a week after that.
