The test evaluates the ability of a cosmetic product to reduce skin shininess and provide a matte finish.
The test involves using the Visioface Instruments to capture images of the skin under parallel-polarized light on each visit. The images are analyzed to evaluate skin shininess, with the decrease in shininess corresponding to the mattifying effect of the product.
The test is useful in determining the effectiveness of a product in reducing skin oiliness and providing a matte appearance to the skin. The test can aid in the development of products targeted towards people with oily or combination skin, as well as color cosmetic products.
