MAC has a wide range of concealers in all different formulas, and a MAC makeup artist can help you find the shade and formula right for you. Elf also makes some really good concealers that are just a few dollars. They literally range in price, from $1 to $3, and are available at Target. I recommend the $3 Maximum Coverage Concealer. Since it’s a liquid, you may need to set it with a powder—try it alone first before adding the extra step.
