To use this MaqPro High - Definition Liquid Foundation, first, shake the bottle well. You can apply it to your face or body using a makeup brush, sponge, or your fingertips. Start from the center of your face or the area you want to cover and blend outwards. When using on the body, make sure to spread it evenly. Remember, this foundation is sensitive to heat and frost, so store it in a cool and dry place. Keep the bottle tightly closed when not in use to maintain its quality. Also, since it's a liquid foundation, avoid getting it in your eyes. If it does, rinse thoroughly with water.
