It does indeed warm my skin tone and provide a nice hint of all-over color without leaving any lines of demarcation or appearing too obvious. The texture is a light mousse that blends easily and feels good on the skin, leaving no greasy after feel, which is mucho important to me. It also did quite well as a primer, making it easy to blend the BB cream I'm currently using and even prolonging it's wear. I did not have as much of an issue with the BB cream settling into my pores.
I've got extremely oily skin and I think it did help a bit with oil control. I was concerned about its shimmer, but found that after applying my BB cream there was no obvious shimmer bits visible, but instead a nice glowing/highlighting effect, which is more apparent in the sun.
I like the packaging and find that one pump dispenses just the right amount for full facial coverage. I'm also a bit fascinated with how those coils look, for some reason.
stila one step bronze retails for $36, which at first glance seems a bit steep. Given it's multitasking qualities, however, the price does seem somewhat more justifiable. I doubt I would have investigated this product if it had not been part of my June Birchbox, but I've got to say it's now going to be my go to primer for the summer!
Disclosure: stila one step bronze was part of my June Birchbox, which I subscribe to for $10/mo.
