I need this too...
Ive tried 50 dollar foundation and matched at the counter... not good enough
Ive tried dermablend.... almost good enough coverage, but its thick and noticable
Ive tried concealer sticks and they seem too thick as well
Tried various primer, various razors, shave creams, mousterizers, cheap and pricey foundations, tinted mousterizers
Ive tried orange lipstick, various red makeups, green primer, pink primer... nothing changes it for me, to me they look worse than the shadow...
Im sure Im doing something wrong... so Ill be tuned here...
I dont even think mine is that dark but I see it in any makeup and its frustrating. Im about to dump acid on my face as its driving me insane. lol

I cannot afford laser or electrolysis at the moment...
I get a good shave and I dont really get stubble till the next morning so Im lost on whats happening... I wish you luck and hopefully we both find some good answers here
