I read that "no tricks" were used in the shots, but then I read that 200 frames were used for each one. I'm sorry, but layering 200 images in Photoshop would be considered a trick in most people's definition. It doesn't diminish the work at all. And I'm sure you could find a lot of young men willing to play with the blending brushes while they work over these images at 100% on a big quality monitor.
Christilou, I have added a NSFW (not safe for work) tag in your post, too...... since they are pretty much naked.
