A few months ago in PDN, a photo editor with a major magazine or ad agency said that if they saw ONE MORE image in a photographer's book of a model with plastic skin they were chucking the entire book right out the window. It's easy to overdo it and end up with something that doesn't look natural.
Something that JT pointed out - the lighting doesn't help that model in that image. Any time you have the light scrape across the skin at an angle it will show ANY imperfection. Beauty shots need to be evenly and completely lit to avoid exposing imperfactions. Any model might have been "exposed" in this lighting.
