Hi,
I'm a performer &dancer (obviously...why else would i be here :-P)
and I am currently performing in an extremely active outdoor daytime show/parade called "Celebrate! A Street Party" at the Disneyland Resort here in California.
Because of the effort and sweat involved with this show (it consists of 3 ten minute mini-shows that encompass a variety of high-energy dance styles, in the sometimes 90 degree-plus California weather) I've noticed that my face looks absolutely HORRENDOUS after I finish the show.My eyeshadow stays wonderfully pigmented, but my skin looks terrible. The problem with this is that it is not a "far away" stage show. We perform out on the street literally face to face with our guests, and even invite them to dance with us on the street at certain points of the show. Being so close to them it makes me feel very self-conscious about how my makeup looks knowing people can see it so closely (and i'd never want to ruin the "disney magic" for them by looking so shaby); but obviously I have to wear a fair amount of makeup...it being a show and all.
and to top it all off, we perform two parades of this a day.
I've been performing for years and even work as a general makeup artist from time to time..but I still can't figure out what's going on.
My foundation is becoming splotchy, cakey, poreousy, and creasy. I've never had this problem before. I don't even sweat "a lot" compared to the other performers due to my natural lack of sweatiness when dancing.
I've been experimenting with different combos of makeup and primer and it always consists of sunscreen/spf, moisturizer, primer, foundation, and a powder to set it (either pressed foundation or translucent). Sometimes I'll set it with a little Fix+ spray as well if my skin is already feeling cakey and powdery.
It's very strange, i've never had to worry about this before.
I've tried MAC, Benefit, and even Ben Nye.

I've been thinking about trying Ben Nye's Color Cake with their translucent powder and final seal. But I'm worried about looking too "cakey" , powdery, and unnatural out on the street. Does the Color Cake have that effect?
I have Ben Nye's cream foundation as well that I'm willing to try, but I worry that it won't be resistant enough.
Do you think this combo will do the trick?
I also may want to try a new concealer for my undereyes and "side nose" areas (i don't know what the correct term is for that... but the discolored side nostril areas i sometimes get) My Benefit 'Erase Paste" works wonderfully, but sometimes gets so cakey and creasey after performing
(which is why I can't use the potted MAC concealer as well) is there any good Ben Nye concealer that won't look so cakey and keep a smooth natural appearance?

any suggestions? I'd really appreciate any input.
I'd generally like to stick with Ben Nye or MAC (maybe even Benefit) since Drugstore makeup isn't resistant enough for me outside of everyday use.

Thank you for taking the time to read my essay here :-P
But after today's literal "melt-down" performance on my face...i HAD to do something.
