Selecting the perfect shade of foundation and concealer may be challenging for all women, but ladies with dark skin may find this process even more difficult. Instead of creating a flawless complexion, skin can appear ashy and gray.

Luckily, StyleList.com reports that due to advancements in cosmetic formulas, foundations are no longer made with titanium oxide, the element usually responsible for making dark skin look ashy. But even with this ingredient gone, how are women of color supposed to locate the right shade of foundation?

According to celebrity makeup artist Sam Fine, finding the perfect concealer is doable, but it may involve trial and error. Instead of purchasing one shade, Fine suggests buying three different tones to see which formula matches skin best.

While trying out multiple products, however, women shouldn’t be set on finding one ideal shade of foundation. “Don’t be afraid to use two brands or two formulas because that’s what makeup artist do,” he told the website.

Fine added that women with dark skin need to remember to shop for different shades depending upon the season. “The foundation that you use in the winter is not going to look as warm and beautiful on you once you get a little color in the summer,” he told the news source. “So, it’s important to switch it up.”
