I never met a posek who allowed shaving. You think the chofetz chayim wrote seforim for fun?
If you accept his Mishna Beruro, you must accept his Kuntres Tiferes Odom, unless it is like the reform / mesorti movement who choose which halochos to keep and which to trash.

He wrote:[5] [removal of the beard with] depilatory cream… I find this matter very painful…I am accustomed to this being prohibited since the earlier generations, and [the prohibition] was very severe…[Jews] have learned it from the non-Jews during their exile…Although this sickness has spread even among the bnei Torah, the issue has not changed as a result of this, and therefore my soul boils [with rage]
