Between hormones and laser treatments I'm at the point where my beard shadow is pretty minimal and I no longer require a full layer of concealer foundation to hide it, but there's still a few bits of shadow on my upper lip and chin that kill any attempts at passing without makeup. I want to figure out a way to hide the shadow in these spots without having to go to the effort of doing a full face of foundation, but if I try and apply it to just the shadowy areas I find that it always mismatches the rest of my skintone

Is the problem that my foundation is just the wrong shade for my skin? Or is there something else I can do to hide just these areas and otherwise look makeup-free?
