COLOR MATCHING: I ordered "Shell" because I'm pale with yellow undertones. Pretty damn good color matching! Like the best I've ever tried. Very pleasantly surprised. I actually used the Youngblood website to reference the foundation colors. So, if you're not sure, I suggest going there. Revlon 150 Buff has been the next closest color match, for reference. So if you've used that, you'll really like Shell. COVERAGE: It is a very light formula, like a thin spread.. so if you have a serious break out, maybe try using a concealer? I haven't tried using a concealer yet. I just apply a little more foundation in those areas and let it dry. I'm coming out of a break-out, so I don't really have a lot of raised acne or extremely irritated skin right now. Definitely have red patches though. Once I apply the Youngblood mineral powder on top, it looks perfectly fine. I also use the Youngblood contour powder kit. Even after all that, I don't feel like I'm wearing a mask. That is to say, my skin can actually breath a little more. I've read from some other customers that the authentic one is thicker, and this one has been watered down. I really can't verify or deny that claim. APPLICATION: I tried using a foundation brush, but it was kinda streaky. I had much better results with my fingers and a beauty blender. I would recommend a beauty blender. Like I said, it is on the thinner side, so it favors more of a natural look, which is honestly great. However, if you also wanted to do a full face, you absolutely can. You can build up the product. Use your powder. Contour. Highlight. LONGEVITY: My skin is suuuuper oily, so if I'm not using a matte-specific formula, I have to use a matte primer or matte setting spray. SKIN REACTION: I was kind of amazed to see how "chill" my skin was after washing it off. I've used Revlon and CoverGirl on and off (periods of wearing or not wearing make up) for a couple years now, and every time I've washed my face I could see how angry, inflamed, and irritated my skin was after doing so - even causing same-day breakouts. Needless to say, putting on makeup became a necessity and torture. After washing the Youngblood Foundation off, my skin actually looked smoother! And it was not inflamed. Like... what? How have gone this long without trying mineral foundation? SUMMARY: I bought these products as a first-time buyer after researching different brands, and reading customer reviews. I was prepared to be extremely disappointed because you really never know.. but I've experienced quite the opposite. Yay! The ONLY other product I swear by is Lush's Color Supplement liquid/creme pot in Light Yellow. That has never ever caused breakouts and also matches my skin perfectly. So, I'm hoping this line of products will be equally promising. I haven't used it long enough to be sure, but I have a good feeling. Feeling good enough to write a premature review. You get way more product in here than you would in a lush pot. Treat yo self grl.
