TO THE KNOWLEDGEABLE KNOW HOWS!! How to slim/contour a round face?

My question is anywho knows how to make your face more slimmer/tighter??? Let me explain...I've always wondered how better I would look if my face wasn't round. I'm not overweight, so its not a matter of exercising or changing diets to make it happen. Its actually just genetics, and most people probably wouldn't even recognize it. But I do! lol...and I mostly like my full face (cheek region) especially when I'm smiling. But when my face is relaxed, my high cheekbones serve no purpose because they hidden by my full cheeks. So I'm wanting to know how I could make me face more slimmer or tighter to acheive that "sucked in cheeks look"kinda semi Victoria Beckhams waif look to make my face thinner and where my cheekbones are able to "pop"......surely I can't be the only women to think about this lol Am open to all kinds of suggestions from products, procedures, facial creams.
