If you have red undertones, you know that it's not always easy to find foundation that matches your skin tone. The good news is that there are many options out there for people with red undertones. One of the best is concealer. Concealer can be used to cover up dark spots, blemishes, and other flaws in your skin. It can also be used to create a more even look by applying it to the area where there is a difference in color between your skin and the surrounding area.
