As someone constantly looking for consistent, non-fail foundations, this one hits the mark very nicely.
I know that this foundation has been recently reformulated, and I haven't tried that version; I got an "older" version of this foundation on sale. Immediately, I gravitated towards the lightest shade. I'm as light as one can get in the winter, so it's quite the lottery game to constantly have to find foundations that actually match my winter face. The shade 405 in the 1 category seemed promising, so I picked it up and began to use it as a replacement, once I've run out of my previous winter foundation.
The color is excellent; I do not have any oxidizing problems with this foundation. That's a huge plus for me. The fair color that was inside the bottle was pretty much what ended up being on my face. A+. Unfortunately, there really is no system in the older version of the line for undertones; this particular one, as most pale foundations do, happened to have a neutral/cool shade. I happen to be warm-toned. Personally, I didn't mind, since my skin is so light it's hard to tell, but if that's something that is an issue for you, then you may want to seek alternatives.
TruBlend has a very thin texture. It's not so liquidy that it never dries, yet its consistency is on the thinner side. I enjoyed that, because a little goes a much longer way this way. In this case, the coverage is light-medium. It's not completely sheer, and it will cover minor breakouts along with evening your skintone. I particularly liked its finish; it feels very natural on the skin, not heavy or like it clogs my pores. My skin could breathe, per sé, in this foundation.
Its staying power is also impeccable! I keep my face makeup on anywhere from 12 to 20 hours per day, and this foundation stays with me through the whole day. I've even woken up from naps with perfect face makeup. For a product which doesn't claim to be longwearing, with some powder it is easily capable of withstanding any daily travails.
The pump bottle is always very much appreciated for liquid foundations. Also, its drugstore price tag of like $6-$7 is hard to beat! I got the outdated version on sale, and I'm not sure if that's still circulating or not, but you can get the previous formula (the one I just reviewed) for no more than $4. Covergirl has been a hit or miss line for me, but this one was definitely a hit. I wasn't expecting much, but it turned out to be a pleasant surprise. I highly recommend.
