I haven't tried the Too Faced Peach Foundation, but I gave the Peachy Primer a try just to test it out. It is pretty good. It's not perfect, but nothing ever is. I think it is worth a try. It is one of the best I've used, just not THE best. I don't think us oily girls will ever be able to get rid of it completely anyway. My only advice really is, even though you're oily make sure you find a good moisturiser to balance your skin when using such mattifying make up products. ☆
