Nanina, here is what I have been using that I've found works for my beard (I've tried a few things, these were the winners), all bought very cheap off amazon or
walmart.com:
1) LA Girl Pro Conceal Orange - Make sure to rub it against the grain to really get it covering the remaining stubble.
2) Rimmel Stay Matte Liquid Mousse Foundation - slightly darker than your skin tone, use to blend over the orange. Doesn't take much, will wind up with a sort of inflamed reddish look around the area the concealer and foundation is. I use the blending sponge on this, brushes just don't work with the thickness of the mousse.
3) off brand Loose Mineral Powder Foundation - Your real skin tone. I bought a set of loose mineral makeup off of amazon for like 30 bucks, I only use the foundation and setting powder though so probably better to buy individually. Use brush to pat it on around the beard area. You can go a little heavy on this and brush off excess later, but be careful if it packs too much because you will get that overly made up look. This is what will cover up the redness and be your "actual" foundation.
4) off brand Loose Setting Powder - I only bother with this if I am going to wear it for a while. This is basically translucent version of the foundation powder I believe. My pack also came with a setting mist I spray over my face if Im bothering with the setting powder, I really don't know what is in it.
I also have a blush and an eye shadow palette but I suck with them so won't comment. Lipstick is simple enough, but of the ones I've tried I'm happiest with Revlon "Love That Red".
For foundation shade, I've had to play a guessing game. My powder has strange off brand labeling and is just listed as "fair", of the Rimmel mousses my actual skin tone is around porcelain because I'm super pale, but I've been getting by with a light ivory. Reviews seem to say the rimmel stay matte foundation is really hit or miss depending on the individual, works for me though.
