Halo Smile claims to give you a whiter smile instantly, which Leslie describes as being similar to nail polish for your teeth. It’s temporary and you can brush it off when you normally brush your teeth. Paola tried the product and shares that there is a learning curve. She said that after several attempts she got to a place where she felt okay with her teeth, but feels her teeth still look streaky, saying its best for pictures because up close you can really tell. Leslie shares that it’s also dentist approved.
