to use concealer, pick one that is 1-2 shades lighter than your skin tone. to use it, dab it on to trouble spots (such as acne, redness, or dark circles under your eyes) and either blend it lightly with a blending brush (you can get one at your local pharmacy in the cosmetics section) or you can use your ring finger to pat it until it blends into your skin.
i hope this helps, good luck :)

Mary Kay markets a very wonderful formula of concealer for your situation that does not flake. Another good option would be to use Maybelline brand concealer.
You can use a concealer to hide the contusion. Pat the skin with the contusion with the concealer and gently blend in the concealer with the surrounding skin to hide the bruise.
First cover up under eye circles by using a concealer brush or your fingertips to dab concealer under your eyes. Apply the concealers under your eyes and blend the concealer in around the edges. Simply dab the concealer with the tips of your finger or brush in order to blend it. Next, apply the concealer to acne and spots. Dab your concealer onto the top of each mark, and then blend softly outwards to your skin. Use a thin layer of concealer to avoid having a caked-on look. If you have acne, avoid using your fingers to blend the concealer because using your finger can spread bacteria. Lastly, you have to set your concealer. Use a loose or compact powder foundation to set your concealer, so it does not easily wipe off.
Concealer is sort of priming the face. If you have circles under your eyes or a blemish you put the concealer on them, blend a little and then, apply foundation. I use MAC concealer and a q-tip to smooth it out.
Concealer is way too heavy to put over your whole face. I would say no, don't use it as primer.
i personally use both.
Cover it up with concealer and then apply pressed powder to set it(;
Use concealer or foundation
Concealer then foundation
try Maybeline's concealer
It really depends on what type of foundation you're using. If you're using liquid, apply concealer after. If using cream, the order is optional. If using powder, concealer goes on first.
