At first,I really like the fact that some Korean foundation now come with more shades and include undertones, that why this foundation got my attention. I read a lot a comments saying this is "Estee Lauder- double wear foundation" but it isn't! The coverage compare to the E.L. is (3.5/5 ~ I have pretty much good skin I would say, I only have freckles and they kinda cover them, but still some still pick through), but the finish of it, it's just amazing that makes me wanna wear it almost every day (when I want more coverage though, lol). But, I wore it pretty much 10-13 hrs just to try if it's good as it claims to be, and guuuurl, it's Soo good! It faded pretty good, of course, you have to powder every 5 to 6 hrs depends on your skin type (I'm have normal skin with some dry areas during winter but, during summer or spring time I'm more like oil combination & now the weather is changing and getting humid & hotter).
In terms of colors, I first picked v04 but it's dark for me, may be if I get tanned during summer, I will be able to wear it (during summer I'm NC30). So later on, I picked v03 which it's pretty a good much (I'm nc25 right now).
Hope that helps anyone, because for me it was really hard to find my shade :(. Anyways, I really like it.
