Researchers believe that they have found a solution for makeup for darker skin tones.
In recent years, the market has been designed for people with darker skin tones, and some brands offer a wide range of tones to consumers.
Now, researchers say they have found a way to create red tones in makeup for darker skin, finding the addition of ultramarine blue, reduces the ash or gray appearance that these products can create.
Gabriella Baki, Associate Professor of Toledo University, said that while some companies have already used their additives in their products, their use is not common.
Uz We hope that our research should give new information about why it should be added, ”he said.
The team says that the ashy skin color, which can be caused by makeup foundations for darker skin, is typically dependent on these products containing larger amounts of black iron oxide.
“Ultramarine blue creates more red and blond tones that are different from black iron oxide, Bak said Baki. “By creating warmer tones, the basic looks more like skin. Baki added that it creates less opaque color, which helps to reduce what is known as “gray casting ..
The new work, which has not yet been published but will be presented at the Spring Meeting of the American Chemical Association (ACS), reveals how the team looks at the effect of incorporating ultramarine blue by creating 20 dust foundations in both darker and lighter tones.
The researchers used a spectrophotometer using the color of dust and visually evaluated them both on private paper and when applied to the internal forearms of the participants.
Baki added that ultramarin helps the creation of different sub -shades, both darker and lighter foundations, but it may be a transformative for the first one because it reduces gray casting.
“Based on our research, we recommend that you combine black iron oxide and ultramarine blue. However, ultramarine blue can be used as a dark pigment.
“For a very dark skin color, ultramarine blue may not be enough to match the skin tone value of consumers, because it creates lighter foundations compared to black iron oxide at the same percentage. If a dark color needs to be created, combining black and blue can only provide a skin -like color than black iron oxide.”
The study provides examples of how to create more inclusive basic lines for consumers. “Ultramarine blue should be added to the foundations of all shades to expand the sub -shades for the same shade and to create more skin -like basic tones,” he said.
