Review on 🦷 Ecco Pure Teeth Whitening Pen - 1-Pack Gel Pen Kit with 35% Carbamide Peroxide - Achieve a Pearl Smile, as White as Snow by Jacqueline Mclaurin

I have been using this pen for teeth whitening for several weeks. I can't say he did anything to whiten my teeth. Maybe my teeth are more difficult to whiten, but given the whitening process with traditional kits, it's no wonder a pen like this wouldn't make a huge difference. I don't want to completely discount the pen as my enamel can also be an issue. For now I guess a stick like this is fine to use between regular whitening/whitening treatments but don't expect it to work the same way as the bowls you use with whitening gel. Because she can't. I'll keep putting the pin to my teeth until it's empty, but don't expect much of a difference between now and then. This can have a bigger impact if your enamel is different from mine. Try it out and draw your own conclusions.
