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 Christopher Jones

I've been using this pen to whiten my teeth for a few 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 regular kits, it's no surprise that a pen like this wouldn't make a big difference. I don't want to be completely devalued. Pen as my enamel can also be a problem. For now I'm guessing a stick like this is fine to use between regular whitening/whitening treatments for maintenance, but don't expect it to perform the same as the trays you use with whitening gel as it can't is. 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.
