When applying BB cream

Sometimes it's fine, but

There are days when things pile up like dirt.

Why is that?

If you get stuck like sometimes, if you have time, try again

It would be good to wash your face and start over from the basics.

It's really frustrating when you don't have time.

Especially when I go to work, while applying BB cream

I do press firmly with the back of my hand, but

I don't know why it's lagging.

If I knew the reason, I would try to fix it before applying BB cream...
