To counteract blueness and dark circles under the eyes, go for a concealer with a yellow undertone that is one to two shades lighter than the color of the skin itself. If concealer is being used to mask pimples, to even out skin tone or to tone down broken capillaries, ensure that the shade you choose has a yellow undertone (pinkish shades will only accentuate redness) and is a good match for the natural color of your skin.

Always apply your concealer on top of foundation and before you add powder. If you try to do things the other way round, you might wipe the concealer off when applying your foundation. To disguise under-eye darkness, gently pat concealer under the eyes using the index finger. Exert only gentle pressure and blend outwards, taking care not to drag the skin.

To conceal bags under the eyes, put concealer on the shadow beneath the bag, not on the bag itself, otherwise you'll end up highlighting rather than hiding the problem. To cover up broken capillaries or uneven skin tone, you can either massage concealer into the skin or paint it on with a brush and blend with the fingertips. To touch out any blemishes or unsightly-looking spots, paint on concealer with a brush.

Remember to start at the centre of the imperfection and feather outwards.
