How do I stop eyeshadow from creasing?
With an oily skin type your best bet will be powder eyeshadows. But as you said, you've tried them! But you could try layering the eyeshadow with a subtle base colour first to help it last longer. I'd stick to matte, neutral shades because creases will be less noticeable.
I love Bobbi Browns long-wear cream eyeshadows and find them really long-lasting. I am also oily. x
