Top 5 reasons I love HiSmile for my fast paced life.
1. The gel is easy to apply.
2. Once I've applied my base foundation I let the whitening do it's magic, while applying my eye makeup.
3. The blue light lets you know it's on and still working it's magic whitening powers.
4. My teeth did not feel sensitive afterwards.
5. You'll here a beep sound once you've finished all of your 10 minutes.
It's great that I don't have to keep an eye on the clock to make sure I'm not over or under the 10 minutes for keeping it on.
