We can all look good provided we have an inch of pancake makeup slathered on, and a 10,000 watt light shining directly on our faces or from the right angle and nowadays, computer graphics. It's all smoke and mirrors, ladies and gents.
I didn't see anyone who looked really bad. One just looked her age. They looked just like we all do, with facial scars and under-eye circles. What was most interesting to me was how they reshaped entire bodies. If you have thighs like normal people, they slimmed you and your face down, if you're so thin you have bony limbs, they fleshed you out, if you have strange contours - frog thighs - then they made you look normal.
Some people look better without makeup. I didn't see Christina Aguilera on the site, but she goes around looking like a geisha with all the shit on her face all the time, but when she's clean scrubbed she looks incredible, young, innocent, freckled, just fresh and amazing.
