Ah, thanks, Marina. I think it's quite likely I was using too much - I have uneven skintone and tend to go for at least medium coverage foundations, especially since I scalded my face last year and it's still patchy on one side. Maybe I should give B&B another chance. To be honest, I was put off all powder (or baked cream, it's all the same to me!) foundations and I haven't used any of my bareMinerals since either. However, I have still got the pots and compacts so I may try again and be sure to let the base dry completely, then check my face through the day in different lights, maybe one day when I'm not going anywhere special, just in case.
You can still use your BM. Just add some to your moisturiser to make your own tinted moisturiser. I've had to use it like that for years as the finish is awful on my skin used dry.
I don't know what to do with my LG B&B, though. Suppose we could always use it on our legs or something.
