Important factors to consider when picking a concealer include skin type, level of pigmentation and the intended use of the concealer. Those with dry skin benefit from a moisturizing concealer, but those with oily and acne-prone skin may benefit from an oil-free formula that does not clog pores.
The most effective concealers for correcting under-eye circles contain lots of pigment and have a thick, emollient texture. This moisturizes and nourishes the delicate tissues in the eye area, minimizing the look of fine lines and preventing skin damage due to pulling and tugging during application. Under-eye circles have blue undertones, and yellow-based concealers neutralize the blue tones more effectively than those with pink or blue undertones.
The best concealers for concealing blemishes are noncomedogenic and highly pigmented. These often come in a pot and require application with a thin concealer brush. Dot a small amount of concealer directly on each blemish, but keep it off the surrounding skin. Add a second coat if necessary. Wash the brush after every use to rinse away skin oils, pigment and acne bacteria.
The most effective concealers do not migrate during wear. To keep the product in the right spot, dust translucent powder over the concealer and lightly blend it with a large, fluffy powder brush.
