A:AnswerYes, all Panasonic Shavers for Men have a pop up trimmer. The trimmer is activated by pushing the button with your thumb. It locks in place so you can shave in both directions without the trimmer collapsing.
A:AnswerYes, you can use shaving cream with this shaver. I prefer shaving gel though because you can thin it with water to make it last a bit longer (not dry out).
A:AnswerThe blades on the Panasonic Arc 3 don't have a height adjustment. Using this shaver will give you a clean shave, no beard. If you are interested in products with height adjustment of the blades, I would recommend a Wahl or similar brand beard trimmer.
