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.
