The BB cream has medium to full cover, depending on the amount you use and way of application, but it doesnt cover very dark marks so you might have to add extra concealer on top of it. it has SPF 42 which i think is perfect to be used in the morning.
I use shade 27 and it is a tad bit darker than my skintone but i can still get away with it, it would be perfect if it was a bit lighter, i can compare the shade a bit with MAC NC 35, but this BB cream is neutral, its not yellow nor pink based which will suit most skintones.
It does last long hours, i can wear it from morning till evening and i still have the full cover effect but the thing i dont like about it that it doesnt dry, i can still feel it a bit wet on my face whether i set it with powder or not, but it doesnt bother me alot because i have used much worse products.
I love to use it in the morning, some girls might think that it is too much (coverage wise) for the morning but i love it, it give me this dewy, bright glowy skin effect early morning instead of plain dull skin.
Before i used to think Missha BB cream no.27 is a bit dark on me until i tried no.23 this shade really shocked me cuz it is grey! Obviously it doesnt match my skintone. Now i know no.27 is my best match. I can control the shade by adding cream highlight or i can mix it with no.23.
I have tried different applications like brushes, beauty blender and Real Techniques which all work but i prefer to use Real Techniques because it blends it smoothly and wont look caky, be careful not to use too much product as it will look like mud on your face.
It is a great product and i will definitely repurchase it but i give it 5 stars simply because the product doesnt completely dry on skin.
