  The thickest skin (epidermis and dermis) is (apart from foot soles and hand palms) found on the back. All your other intended areas are also quite thick.

 

  The thinnest skin is on the upper and lower eyelids (0.3-0.5 mm). Relatively thin is the skin on the top of the collar bones, in the groin and in the armpits. The neck has usually thinner skin than the face. The face doesn't have the same thickness either. The centre of the forehead is thicker than the sides, the chin is thicker than the cheeks etc. It can vary with age and it varies individually as well.

 

  A 2 mm roller doesn't penetrate the full 2 mm into the skin. Males have usually thicker skin as you mentioned. If you were a woman, I'd recommend using a 1.5 mm roller instead. You can control the penetration of the needles by putting more or less pressure on the roller.

 

Getting pinpoint bleeding is normal and OK.
