seems like everyone here has tried and has an opinion about mac studio fix, but what about studio tech? i really like it, it's what i wear if i'm in a hurry and don't have enough time to get my armani liquid makeup just right. it has great coverage, it stays on all day, and it doesn't irritate my skin at all. if you have a heavy hand, it's easy to make yourself look too 'made-up,' but a little moderation goes a long way, as we all know! thoughts? experiences? tips?
