Yes - I think they all have a small amount of self tanning chemical in them. I have tried a couple sold in tanning bed shops and they both seemed to make the tan deeper quicker. Some after sun lotions also have a small amount of self tanning chemical in them and they also work very well to deepen a tan without it looking fake or orange - they contain a smaller amount of the chemical than a self tan cream/lotion does so it's a more subtle effect.
