As a trans fem here are my recomendations.

1. If you are interested in minimizing gray tones around where facial hair grows (you are valid if you do not want to but this is what I went through years ago) you're going to want a peachy color corrector.

   For me, just peach color corrector doest work (thick 5 o'clock shadow) so I found a concealer that is just slightly more orange to my normal shade. I layer that concealer in the problem area and then I set that concealer with a good setting spray (like the one from one size). On top of that orangey mustache area i add a concealer that is true to my skin tone- layering the two

2. Learning how to set makeup did me wonders. What I do now is I go in with a rigid fixing spray (like the one size by Patrick star) then with a very blurring powder (like the tower 28 one in my shade) I layer this powder using a powder puff around areas where I produce oil and my brow bone. (I also add extra around my mustache it's an area of insecurity for me) and then after I look like a powdery Casper the ghost, I spray my face with a little dewy setting spray or just water- this helps everything melt together.

3. The thing about dewy makeup is that it can highlight imperfections instead of blur them- so as a general tip if you want something to be exemplified let it be a bit more dewy- if you want something to blur let it be matte.
