As far as the skin care things go, I can't tell you, unfortunately. I know personal fitness well, but I don't know dermatology.
The other stuff is inaccurate, or at least it misconstrues things. Barbells are better than dumbbells for health (in terms of performing functional movements) because they work the entire body rather than singular muscle groups. Barbell deadlifts are incredible for your abdomen, as well as great for your glutes, for example.
Soy products also do not increase estrogen. /fit/ people who tell you this are dudebros who can't into phytoestrogens.
As for "testosterone causing greasy skin, breakouts and repugnant smell", I know people at 120kg who lift very heavy yet have no issues with any of this. This doesn't even happen to every powerlifter on roids. It's not an issue for you. Naturally, you might require skin care products for perfectly smooth skin etc., but make no mistake, tons of women and feminine guys do as well.
