Discuss the chemistry and application techniques behind "baking" or "cooking" makeup, particularly in the context of setting powders and concealer.

Baking or cooking makeup is a technique that involves applying a generous amount of translucent setting powder to areas of the face where concealer or foundation has been applied, allowing it to sit for several minutes to “bake” into the skin before dusting off the excess powder. This technique helps to set makeup, minimize creasing, and create a smooth, long-lasting finish. The powder absorbs excess oils and moisture, while the heat from the skin “cooks” the makeup into place. Baking is typically used for areas that tend to crease or become oily, such as the under-eye area and T-zone, and is popular among makeup artists and beauty enthusiasts for achieving a flawless, matte complexion.
