Non-Comedegenic - Say what now? To me, this sounds like my foundation doesn't come with comedians in it...which I am actually quite grateful of! Non-Comedegenic basically means that the products does not contain any kind of oil. This is specifically good for anyone with oily skin, or who is prone to break outs (Perfect for me then). The fact that the product isn't oily, means that it won't block your pores. Blocked pores produce comedomes, or black- and white-heads to you and me, so comedomes are definitely not a good thing!
