This ad uses minimal Photoshop treatment and I dig that. How can you tell? The first giveaway is her teeth. They’re natural looking, not like those freakish, glistening, blinding white teeth you see in most ads.
Next, look at all the freckles, moles and other “imperfections” you can see on her face and shoulder. That’s not stuff you typically see in skin care ads. Finally, the fine wrinkles under her eyes and at the corner of her mouth have not been erased.
As a comparison, take a look at my unbustable ad next to a typical ad. It’s not until you consider how real skin actually looks that you realize how over-Photoshopped most images in media are.
