Younger facial appearance is attributable to a smooth skin surface over the entire face, while an older facial impression is due to wavy shadows under the eyes and/or around the mouth that appear as irregular or noticeable contours. Kao researchers concluded that contours and shadowing were major factors contributing to observers' impressions of a person's age.
The newly developed "Face Lamp Powder" allows more light to be absorbed by the inner skin in comparison with the Kao's existing powders. More light penetrates and disperses with "Face Lamp Powder"; the skin surface becomes more luminous and reflects light in all directions over its surface. The face looks more brilliant from deep within the layers, and wavy shadows on the surface, which accentuate facial maturing, disappear. SOFINA Primavista users naturally convey a youthful appearance.
