Tips for Hiding Beard Shadow? (New to Makeup)

Hi everyone! I'm new to makeup and just recently started crossdressing. My question is: how can I get rid of the gray tone from my shaven beard? Any tips? I've been using foundation and powder on top, but I can still see the gray in some pictures. Also, the texture feels a bit off since that part of my face isn't as smooth as the rest. Any tips or advice for a newbie girlie pop?
