Crest 3D White Professional Effects Whitestrips

Hey guys so lately I've been trying out a teeth whitening product, the Crest 3D White whitestrips and i wanted to share my thoughts about this product. This product is enamel safe and it comes with 20 whitening treatments, each with upper and lower strip. so what you do is apply the gel side strips to your top and lower teeth, used for 30 minutes, for 20 days and you'll see results in 3 days. Now for me after the third day of using the whitening strips my teeth became sensitive, so i stop using them. When i started using them again i only used them twice a week and by doing this my teeth sensitivity didn't persist. I'm not saying that this is what you should do if you have the same problem as i did but this is what worked for my teeth. Another thing i notice was that after removing the strips you can kinda feel the whitening gel on your teeth but i usually just spit it out. So after a week or so some whitening occur but nothing dramatic. After the second week i definitely notice more whitening happening. with that being said i would totally recommend these whitening strips. This product works but not only that this product got a Good Housekeeping seal which that's a plus for me. and remember "if you're not whitening, you're yellowing." in another note this product was complimentary from influenster.
