Hmm... I've tried the milk of magnesia thing as a mask to try and cut down on my oily skin and it didn't seem to do much.. I only tried to do it under my makeup a couple of times, because It seemed like a big pain in the butt and I'm very time limited, but I'm not sure it did much there either.
Yeah, I'm one of those people who are scared to try products too, because I'm afraid they'll break me out. Lol. and I have OILY skin. On hot summer days I have to stay out of the heat as much as possible and powder like crazy if I do wear makeup. Sometimes I'm just so tired of the oil and sweating that I won't apply makeup until it cools down. I usually have no other choice but to reapply my makeup by the time the sun starts to set if I want to go out with friends because my face looks Soo cakey. Argh.
I should try the hairspray thing... and I actually have a makeup sealant by Kryolan that I bought for facepainting, but I don't use it much because I'm always afraid that I'll accidentally get some in my eyes, cuz it STINGS LIKE THE DEVIL. lol. Then again, I'm desperate enough to try anything with how much I wear makeup, lol.
