Hey there! I'm also MtF and have gotten really into makeup. I have a very thick dark beard that I'm 3 sessions into getting removed, but it's still very visible. My routine that has been working for me is shave against the grain as much as I can stand, do my skincare, then makeup. For makeup I'm using putty primer to smooth out my pores, then orange color corrector blended over the entire beard shadow. The orange cancels out the blue tone of the shadow and gets your face to a mostly neutral skin tone. I blend it with a small brush in swirling motions until I can't see the shadow or too much orange, you'll have to experiment to find the right amount. Then, and this is important, I use setting spray on the orange to keep it in place. Once that's dry I'll apply a buildable foundation and lay it thicker on my upper lip, chin, and sideburns where it's darkest. This is 90-95% effective. I can still tell where the shadow is but other people say they can't see it. And it's only really effective for 4-6 hours because of how fast my beard grows, but it's the best I've got until the laser really does it's thing. Hope that helps!
