Review on 🌙 MOON Teeth Whitening Pen - Elixir III by Kendall Jenner: Brush for a Dazzling Smile - On-The-Go Whitener, 30+ Uses, Vegan & Refreshing Vanilla Mint Flavor by Kimberly Evans

I've never used a whitening pen or anything like it and I really wanted to love the moon whitening pen because it has natural ingredients, but it's not for me. Although it wasn't touching my gums and there was only a thin layer of product on my teeth (I think it was light, I had a hard time telling how much product was actually on the brush after a few swipes), I felt the product. ...on the teeth and on the gum line. It was a burning sensation/irritation that I didn't want to repeat. I felt the need to rinse my mouth but wanted to try the product. Otherwise I think the product has potential. I would say my teeth are whiter (not necessarily whiter, but they looked bright, shiny and clean after use). I would like to use the product more but the irritation was making me nervous. It was noticeable. However, I will say that I love the sleek, thin packaging of the product - it looks classy.
