You shouldn't have to think about your smile.

Not when you're laughing.
Not when someone takes a photo.
Not halfway through a date.

But once you notice the yellow, you can't unsee it.

So you fix it.
Then think about fixing it again.

Kigume is 30 seconds.
Purple helps cancel the yellow.
Swish. Spit. Forget.

Coffee still tastes like coffee.
Your morning still takes the same amount of time.

The only thing that changes is the thing you stopped wanting to notice.
