Yes, I think you can compare it to applying make-up. You apply a little here and there and then carefully blend the colours together so there are no harsh lines. I don't use make-up myself, so I can't tell you how it works, but it's definitely similar, so if you do use it, I'm sure you're very good at it. The only difference is that with pastel chalk you have to rub very hard, but that also depends on the type of paper you use. A sponge or cotton buds over a piece of paper can also help to spread it more easily, and of course the number of layers you use.
