For many women, the most favorable facial profile is V-shaped or a slim oval; narrowing from the cheeks down to the chin to resemble a “V.” This shape is interpreted to be more attractive, feminine and younger. Aesthetic and invasive treatments to achieve this look have become increasingly popular. There are also non-surgical options to achieve this effect such as the use of onabotulinumtoxinA, face rollers, heat masks and other topical skin care products for slimming and firming the face. These non-surgical treatments gradually change the face, resulting in a thinner look. Another option, explored here, is to provide a slimmer appearance without physical change—i.e., the use of makeup to create the illusion of a thinner, V-line face. Described here is a facial powder formulated with layered color-travel pigments to provide such an effect, and evaluations to determine its efficacy.
Studies have shown that color-travel pigments provide angle-dependent optical effects that can be beneficial for cosmetics, such as to contour the face. For the present study, a facial powder was formulated with layered color-travel pigments composed of mica coated with titanium dioxide, iron oxides and silica. These multi-layered pigments reflect light at specular and diffusion angles to impart a color-flop effect of brightness and darkness, respectively. Figure 1 shows a schematic of the pigments with these light reflection effects.
In relation, facial powder is one of the most fundamental and commonly used makeup products. It is easy to use and its effects to improve appearance are instant, immediately covering one’s complexion and imperfections, absorbing grease and oil, and giving a smooth, matte finish to the face. Facial powder was therefore chosen as the best vehicle to employ the described color-travel pigments. Following are assessments of the pigments themselves and the facial powder containing them, to determine their ability to highlight and shade some facial areas, and impart a more V-shaped look.
