Totally works

I just tried this for the first time and wasn't sure if it would work, but I'm a believer. You only need to use a minimal amount.
Input it on in the evening and voila, I wake up in the morning with a tan.

Lightweight self-tanner

This is a good self-tanner. It's lightweight, provides a good colour in a short amount of time and is a great price. I prefer using it at night to develop the colour, but it can stain your sheets if it rubs off.
