[Analysis Case] Observation of Puff Surface Shape
Observation of the puff surface using a digital microscope.
The surface shape of foundation puffs and the adhesion of cosmetics were evaluated using a digital microscope. The digital microscope has a greater depth of field compared to optical microscopes, allowing for accurate observation of large uneven objects that could not be focused on with a microscope. The observation results of commercially available foreign puffs are shown in Figures 1 to 4. The surface shape of the puffs and the adherence of the foundation can be confirmed. Additionally, as shown in Figure 5, it is also possible to directly observe the surface of the hand.
