To me this just sounds like a marketing fad, like mineral powder was a few years ago. The idea that a product can do everything in one step sounds nice in theory, but probably isn't realistic in practice. For one thing, I do not wear the same amount of makeup as I do sunscreen or moisturizer. So if I'm only putting on enough to even out my skin, I won't be putting on enough to moisturize or protect my skin. But if I apply more, it would look and feel way too heavy. This is just a supposition, but I'm guessing these products are, at best, able to do one or two things well. Unfortunately my go-to product has been discontinued and replaced with a BB cream. I hoped it was just their old stuff repackaged, but it comes in fewer shades and the coverage and staying power isn't as good. It just seems to try and do too many things and fails at all of them. So what's the consensus? Here's the ingredient list for the BB cream that replaced my beloved tinted moisturizer:
