Professional mode: After you apply chemical sunscreen on your skin, the sunscreen will absorb the UV radiation scattered on the skin. When the ultra spectrum camera captures a small amount of UV ray reflection in an area, the area in the image is displayed in black. After this mode is enabled, the areas where the sunscreen is evenly applied are displayed in a dark color.

Color mode: The artificial intelligence algorithm is used to integrate the sunscreen test result in professional mode into the color image. After this mode is enabled, the areas where the sunscreen is evenly applied are displayed in color, and other areas are displayed in the regular skin color.
