Makeup Airbrushes

What is the big deal about airbrushed Makeup?
So, I got my Makeup airbrushed twice at a salon, and I really don’t get how it’s better? It didn’t cover ANYTHING, my skin looked the same. She had to keep applying more, and I ended up looking like I had a bunch of Makeup caked on my face. And my skin isn’t bad. I have no acne problems, just some redness on my face.
And once I got it airbrushed at a salon, the otehr time was at Sephora. So it wasn’t the equipment they used.
airbrushed Makeup is as flawless as cosmetics can get. if done the right way no will will be able to notice because there is no indication of where it begins and where it end. not to mention is has this beautiful glow.
