1 piece of make up for oily acne skin

[Satorye]

I'm willing to spend up to £30 for some sort of 2in1 powder that won't need reapplying and will stop my face from oiling for 6-8 hours at work...also that won't need tools as I got rid of my make up set...so really looking for 1 piece of make up(max 2)that will last at least 2-3 weeks.
Anyone have idea?

Not makeup but have you tried the body shop tea tree acne skin care? I have oily acne prone skin and after two weeks my skin is so much clearer. I broke out the first week but I'm amazed at the change in my skin.

MAC studio fix powder (it's a powder foundation). Comes with a sponge, very good and long lasting for oily skin, and one compact should last you several months.
