Hiding Beard Shadow

From estrogen.fyi

Hiding beard shadow requires the use of concealer and color corrector with a special technique.

Beard shadow is more than just a darker area of skin; it usually appears with a blueish or greenish hue based on skin undertone. You need to use a complementary color corrector with a tone which can neutralize the hue of the beard shadow. Then, apply concealer on top of that in repeating layers to achieve a more uniform look.

After this you can still use foundation and rest of your makeup as you normally would.
