Photoshop Elements 3+
GIMP 2.2.6+ (Not 100% functional)
Description: Made for painting realistic skin textures. Great for digital painters, obviously, but also can be used to create textures and for photo skin retouching by anyone. These will also smooth out blemishes and such on skin and make it look professionally airbrushed. Included as well: freckles and facial hair (stubble) brushes.
I highly recommend you check out my tutorial for using these below! (It's made in/for Photoshop, but the concepts will apply for GIMP, as well.)
These are the brushes I use for my own digital painting, when painting skin. (slshimerdla)
