To use this foundation, start by cleansing and moisturizing your face. Then, take a small amount of the foundation on a makeup brush or sponge. Apply it evenly on your face, starting from the center and moving outwards. You can build up the coverage as needed. If you have oily skin, you may want to set it with a powder for a longer - lasting effect. Store the foundation in a cool, dry place, away from direct sunlight. Make sure to keep the cap tightly closed to prevent it from drying out. Don't share your foundation with others to avoid the spread of bacteria.
