Texture: It's like a thick moisturiser, so it's not the lightest on the skin, but it spreads easily and since it's so tacky, you have plenty of time to blend it. The texture reminds of Nivea's face sunscreen and it remains a bit tacky on the skin for hours. It blends well and it looks good from the start. I've used all manner of applications and this works with everything, though with a brush some streaks may remain and you have to use your hands to blend it in better. 

Edit: Now I don't find it stays tacky on the skin for a long time, but my skin is drier. 

Coverage and finish: It covers a lot, I'd say it's at minimum a medium coverage formula, but in the quantity most people apply it's medium to full, maybe even full. I apply much less of foundation in general than I read/see people use because I don't need much and I don't like the heavy feeling of foundations. Finish is very dewy on my normal skin and it start to crease fast under my eyes and eyelids, plus it at times even smudges my mascara a bit, so I powder this straight away. I went without powder for my day test where I don't use anything with the foundation nor over it and this got less shiny as it fully set, but not a lot.

Edit: While I still find it more of a glowy foundation, it's not as slippery on my skin as it was then and it doesn't crease. Now it stays put. It's a foundation I like to wear especially when my skin is very dry.

Staying power and wear: I said this looks nice freshly applied, not super natural, yet ok for high coverage. However, it quickly becomes strange. It becomes more obvious and on places the texture of the skin doesn't look nice, though it doesn't become patchy, just kind of clingy.  It wears well though, it can last the day without rubbing off too much, but I find Clinique's Even Better Refresh is better, due to not being so dewy.

Edit: It wears beautifully now. It stay even, there's no clinging, sometimes it can look obvious when I apply it, but it becomes better and more natural with time. That clinginess was a consequence on my use of retinol and it happened with most foundations for months, until I gave it up. 

Shade: Fair is what some other companies would describe as light or fair light, so it's not as pale as it should be. When price for a foundation/CC/BB is so high, coverage described as full and the product is so popular, there should be a lot more shades and undertones. Fair is comparable to Healthy Mix Serum 51, which I believe is most similar to Mac's NC15. The undertone is not strong, but it leans to warm.

Edit: Adding a comparison of Fair and new Fair Ivory. Difference is very small, which is such a shame. I'm still hoping that It Cosmetics does it right and releases a lighter shade. 

Scent: I didn't expect this to have a scent, but it has one of those herbal/natural cosmetics type of scent. It's only noticeable at application.

Packaging: I have a small travel size with 12 ml that comes in a tube with a classic cap and nozzle, while the original comes in a squeeze-like tube with a pump. Mine was deceivingly full, but there's actually not that much product inside as it looks. 

Price and availability: I got it on Cult Beauty for £13.00 (12 ml), while full size costs £31.00 for 32 ml.

I'm not as impressed by it as many reviewers, but I wear it when my skin feels more dry than usual. It feels like a heavy moisturiser that is very slowly sinking it, however, I could get over that part and though it really covers a lot, I don't love how it looks on the skin on its own. It's very shiny, which I suppose should be expected from a product with such high spf, still I can deal with that with a powder, but I don't look how obvious it can look on the skin. While it doesn't sink into pores, it sits strangely on some parts on my face and I prefer other foundations for the job. Those with oily-combination skin might not like it at all, though I can't say for all and overall this formula looks to me as more for dry skin. Still, this has a lot of upsides, in particular the spf with mineral filters and good ingredients, so if you're used to and want high coverage this is worth checking out - I still wear it of course even if it's not my favourite, though to be fair there are a lot of Korean BB/CC creams with great SPF that can do a similar job and are cheaper.

Edit: Now that the problem of it starting to look strange in time is gone, I like this a lot. It got a ton of coverage, so much I don't need a separate concealer, it looks smooth, glowy and on most occasions nicely natural. I'm still not sure about it being very suitable for oily skin, since it is quite a rich formula that suits my dry skin. Too bad It Cosmetics didn't do right with the shades yet that's why I love Missha  M Perfect Cover BB Cream RX SPF 42 PA+++ in shade #17, but I enjoy wearing Your Skin But Better, especially when my skin is drier.  

Have a great day!
