Review on Venus Visage Teeth Whitening Pen: 2 Pens for 20+ Uses, Effective & Painless, Sensitivity-Free, Travel-Friendly and Easy to Use for a Beautiful White Smile with Natural Mint Flavor by Amy Gregoire

UPDATE (06/02/2021): The whitening effect lasted 3-4 weeks after stopping the application, so if you are looking for a quick solution (e.g. for a photo shoot, meeting etc.) this will do the job perfectly . However, if you're looking for more permanent effects, you should look elsewhere. Also, my pen broke after about 10-12 uses (the twist mechanism kept clicking as it twisted instead of pushing the gel out). So the quality was a bit disappointing but the support team sent me a replacement which I haven't used yet. So I might just get a faulty pin. I gave away the second pen from the packaging, so I can't say anything about the quality of the second pen. ORIGINAL REVIEW (4/20/2021): I was hoping this pen would be easier to use than the Crest I whitening strips. It has been used for years as this pen requires you to keep your mouth open for 30 seconds. However, I didn't expect it to show results so quickly. I noticed my teeth were whiter after just a few days of use! It is recommended to use bleach twice a day. I've only used it once a day and I've still seen very noticeable results. I've been using it for almost a week now and I can see my teeth getting whiter and whiter. I have read that the effects of this bleach only last a few months while the effects of the strips last 6 months. So I'll try to update my review as soon as I know, but so far so good!
