Just a quick chime in...Back when I was transitioning, I wish they had IT cosmetics! They're got a nice red-neutralizer for any blemish/irritation issues, and their byebye under eye works magic for covering as your final concealer....it clings to skin and looks like skin, not concealer.
To cover shadow, I recommend an old stand by from ben nye...try that as a base layer, and blend with a brush like the one that comes with the IT cosmetics red neutralizer... Then use the IT bye-bye on top of the ben nye(that rhymes lol)...and gently stipple your foundation of choice overtop...be sure to blend the edges well.
Please please avoid eletrolysis if you can!! I regret ever ever having done it!!! I had holes for several years from where I had it done, and then white splotches. It took years and treatments to reverse the damage...All I needed was to have a couple of sessions with an alexandrite or ruby laser and I was gold. I hate electrolysis and think they should all be outlawed! There's enough laser technology out there that nobody should ever have to have holes in their face to get rid of unwanted hair.
