Definitely airbrushing, but they also work with pros all day long who know exactly what to do to make their skin flawless.

Also, not all but a lot of celebs wear a lot of makeup. Case in point - Kardashian Klan.

I just checked Amazon and they actually have the best deal on this.

We really can't compare ourselves to the celebrities. They have a team of personal trainers, stylists, pro makeup artists & most importantly their pcitures are being AIRBRUSHED. They look good to begin with and then they're being photoshopped to remove every last line and freckle. If you want your skin to look smoother, have a series of glycolic peels. You can even do them yourself at home at a very reasonable price: try the Brazilian Peel. They sell it at Sephora.
