Using this liquid foundation is a breeze. First, shake the bottle well to blend the formula evenly. Then, squeeze a small amount onto the back of your hand. Use a makeup brush, sponge, or your fingers to apply it gently to your face, starting from the center and working outwards for a smooth finish. When it comes to storage, keep it in a cool and dry place, away from direct sunlight. Avoid freezing the product as it may affect its quality. Also, make sure to close the bottle tightly after each use to prevent the foundation from drying out. If you have sensitive skin, it's a good idea to do a patch test on your wrist before applying it to your face. This way, you can enjoy a long - lasting, flawless makeup look with this great liquid foundation.
