Yeah its hard to tell because your hand is sort of in the way. I think I can see VERY minor recession in your second picture. How old are you though? , this could just be your hairline maturing a bit. If you have a picture handy from say a year ago it would be useful to do a comparison with. Just to verify, that area next to your sideburns you shaved correct? But yeah going to a derm is a good idea and also take pictures over the next like year, I think basically everyone should take pictures and have a little file on their computer somewhere just to keep track of their hair.
