I love using Studio Tech, but sometimes my skin reacts negatively. Other times, I don't see any breakouts after using it. It really depends on how my skin wants to behave at the time. LOL But, I find that it looks really nice in photographs. Even when it does get warm, the "glow" (as I like to call it) that develops can be tamed with a little powder...no biggie. I think Studio Tech is a good product for a night out when you know you will take some photos or just a photo shoot. Personally, I wouldn't tell anyone to count on it if you plan on sweating a lot or hanging out in the sun. I love it at night time when you can also play with more color. It gives you that nice smooth canvas if you are able to set it well with a loose powder. BTW, I have kinda oily skin too. It's not horrible, but I definitely need my powder to keep it at bay.
Try everything -- that's my best advice. You'll never truly know what works and what you like unless you do. And even if you buy something and find that you don't like it much for yourself...you know that you will always be able to use it on a client (and it may work perfectly for her). Just experiment and have fun.
Like I said, I love Studio Tech when my skin is acting right for me. And I think it looks nice in photos...but don't count on it to just last and last and last if you're doing too much. :0)
