You know what, if that's what you want, then yes, I can. I'm tired of people saying that photographers shouldn't be airbrushing their photos, as it hinders authenticity. I'm here to say that if my client wants to be airbrushed, then hell, they're going to be airbrushed.
If you're not feeling your best self, but still picked yourself up and dragged yourself to the studio for a shoot, and if it would make you feel more comfortable for me to airbrush your skin to digitally heal your stress breakout, then sure!
Some photos are airbrushed by default, anyways, because some things like shadows, texture, or shininess can distract from the main focus of the photo.
I have included a clause in the photography contract that mentions this, too.
