This has been around for so long and received so many reviews, there's probably not a whole lot I could add to the conversation, but I'll try, because I love this foundation. And I do mean LOVE - if this was discontinued, I would feel lost, it's such a unique product and it's my everyday foundation.
The first thing to mention is the texture, which probably is the main thing that makes this so unique: It'a a water-based foundation (remember to shake it!), so straight from the bottle, it's very watery and very sheer. I think it's best applied with fingers - it'll make a brush sticky and a sponge seems counterintuitive with an already watery, sheer foundation.
As you work it in, the texture changes; it thickens and becomes tackier, more opaque. It's very buildable, so you can start off with a sheer base, work up the coverage, and add layers as needed. Moving it around and working it is key for coverage - if you just apply this evenly like you would a "regular" foundation, it'll end up very very sheer. It takes a while for it to set, and it often remains tacky:ish in places, so even on my dry skin, I need a blotting or setting powder.
I have never had this look cakey, and it never seems to emphasise dryness, flakes, rough patches or pores. It just kind of glides on and brightens, evens out, adds glow, and provides as much coverage as you choose to build up. (I doubt you could get full coverage out of this, though.) If you have more noticeable blemishes, you will need a concealer on top of this, but for me, any foundation that covers as much as a concealer is too much - I like my foundation to look like skin, but better.
A little goes a long way; a few drops can cover your entire face if you like it sheer, and a few more will add coverage. I get the 120 ml bottle for about 40 euro, but it lasts for a long, long time even if I use it daily, so in that context, I think it's very affordable. I've heard that over time, it can separate or change in texture somehow - I've never had that happen, but if you don't plan on using it often, there is also a 50 ml bottle available.
Looking at the MAC website, there's surprisingly few shades available, but you can probably mix them. I use C1 with white mixed in. I have yellow undertones but I'm prone to redness in some areas, and the C1 evens that out nicely.
There's no SPF in Face & Body, and I think it's supposed to be water proof, or at least water resistant, but let me tell you from experience (unfortunately) that if you cry wearing this, it does come off. Maybe not if it's a regular little wedding cry, but pretty quickly if it's like a when-Mufasa-dies cry or a just-got-broken-up-with-and-I-feel-like-someone-stabbed-my-soul cry.
- Versatile! Buildable from very sheer to a good medium.
- Texture: looks like skin, but really helps even out the look of dryness and enlarged pores.
- Dewy finish that looks nice on dry and/or mature skin.
- Relatively affordable as an everyday foundation because a little goes a long way.
- Best applied with fingers, you don't need to get any tools dirty.
- Never seems to cake, ever.
- Really different texture compared to most foundations, so there's a bit of a learning curve with the application.
- Takes a while to set, and even when it sets, it doesn't completely dry down. (So I don’t really know how you would use it on the body and not have it transfer to your clothes.)
