Review on 🦷 Proven Results: Professional Effects Teeth Whitening Strips - 20 Treatments and 40 Strips Kit, Eliminate Coffee, Tea & Tobacco Stains, Gentle on Sensitive Teeth by Heidi Nelson

I've been using these strips for about a week and my teeth are already a lot whiter and brighter. Unlike other popular brands I've used, these strips are easy to apply and don't slip off your teeth. There is a difference in the amount of whitening gel on these strips which can contribute to the effectiveness of the product. It is best to brush your teeth after use to remove the gel. Your teeth will really shine (in a good way). The kit includes a color chart to help you evaluate the results. I highly recommend this product - it really works!
