Is there a more science-y looking primer than Stila One Step" Seriously, I don’t think so. It’s got that double helix-looking DNA thing swirling around in the bottle, which is kind of cool.
Stila’s moisturizing primer
So, Stila has a bunch of different face primers. I know there’s one for illuminating and one for color correcting, but One Step is their moisturizing, smoothing water-based primer.
The clear liquid surrounding the helix is a combination of water and other moisturizing ingredients. The primer contains a mix of vitamins and 15 botanicals, buuuuuut the plant extracts are mostly all down near the bottom of the ingredient list, which is just something to keep in mind.
I’m not completely sold on this primer’s hydrating power… I have combination skin, and I don’t really feel like this primer does much for my dry spots. (Side note: If you want straight-up hydration, check out MAC Natural Radiance.)
