This has really gone way off this entire thread.
Again, all or almost poskim are not against not growing a beard. Using powder or cream is muttar as well as tweezers. There is a debate regarding using an electric shaver, some poskim matir some oser. Recently there has been an effort in E”Y to come up with an electric shaver, which is kosher based upon all the shitas. The shaver apparently already exists for quite some time now, and got big publicity in the newspapers.
Regarding Kabbalah, there is as well a debate. Some are of the opinion one should not even touch his beard. Some say one most grow his beard, and some including a present day Godel say one should not grow a beard.
A final debate is based upon tzuros hayid. The Chassidic as well as the previous generation Sephardic were clearly against shaving. The Litvishe-Yeshiviish were in favor for bochurim. That is to the exceptions of some, like the Chazin-Ish and his following, Reb Chayim Kanievsky etc.
