how do you use liquid concealer if youre not going to use foundation?if you can send me links to videos or tutorials or just tell me yourself that would be awesome!

Make sure the concealer matches your skin tone, and apply it with a small brush to your trouble spots. Brush the concealer on and into the spot, using just the tiniest bit of product. Then lightly blend it out into the rest of your skin. It's best to follow the concealer with a pressed or loose powder that matches your skin tone just to make sure everything is blended. Apply it with a big, fluffy brush. You only need a little bit.
