Concealers make it possible for you to hide minor flaws in your skin and life-style excesses such as broken capillaries and dark circles around your eyes.
Concealers are of a denser composition than regular foundations and are generally available in sticks, tubes, pots, and creams. Concealers can be used to cover blemishes, dark spots, rosy areas, marks, veins, freckles or under eye circles.
How to Apply Concealer
Your concealer should be one shade lighter than your foundation as using one that is too light or too pink will emphasize the dark areas e.g. around the eyes instead of concealing them. Choose a colour with natural undertones if you are fair skinned and yellowish if your skin is medium to olive toned. As with foundations, avoid pinks.
Concealer should be applied with a small fine tipped brush for an accurate application ... blending is the key.
Finally you should set your concealer with a sheer, translucent powder to prevent creasing.
