The stinging bit starts to go away after a while for the most part. After using it for several months, it pretty much feels like putting water on my face at this point.
The liquid version, for me anyway, stung like that for 30+ minutes after every single application. I'm sure that lessens with time as well, but.... 0/10 would not do again.
If I remember, I'll post some more shots later today. I ended up getting a good quality boar bristle brush, beard oil/shampoo and trimming a lot to shape it up. The whole thing is looking much more cohesive, tame and just more wearable in general now. Though it's still nowhere near as full or dense as I ultimately want it to be, I finally feel comfortable with saying I have a beard now.
