Using this foundation is easy. First, clean and moisturize your face. Then, squeeze a small amount of the foundation onto your fingertips or a makeup sponge. Apply it evenly to your face, starting from the center and moving outwards. For a more natural look, blend it well into your hairline and jawline. When it comes to storage, keep it in a cool and dry place, away from direct sunlight. Also, make sure to close the cap tightly after each use to prevent it 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.
