Baking in makeup refers to the technique of applying concealer and loose powder to specific areas of the face, such as under the eyes, to achieve a crease-free, flawless, and long-lasting finish. This method is popular for creating a matte look and is known for its ability to set makeup and prevent creasing over time. The process typically involves applying concealer, followed by a generous amount of loose translucent powder, allowing it to set for a few minutes, and then dusting off the excess powder for a smooth and creaseless finish. Baking can be particularly beneficial for special occasions or performances where makeup longevity is essential, as it helps to absorb excess oil and maintain a budge-proof look.
