Latest beard dyes: what’s the best?

I’m been spammed on social media recently with ads for different brush in beard dyes.

I currently use Grizzly Mountain. It works well but it’s messy and time consuming (although I only use it every 10-14 days).

I can’t use Just For Men beard dye as it burns my skin. I gave it a go again 1.5 years ago and my chin was red raw and blistered (again!).

So what are some of the new permanent beard dyes that you recommend?
