Using this blush is super easy. First, take the product in your hand and twist the end of the sponge applicator in a clockwise direction. Keep twisting until you see the blush appear on the sponge. Then, you can directly apply it to your face for a lovely rosy glow. Before you start using this blush regularly, we highly recommend doing a patch test. Just apply a small amount of the blush on a small area of your skin, like behind your ear or on your inner wrist. Wait for a while. If you notice any redness, itching, or discomfort, don't continue using the product. As for maintenance, keep the blush in a cool and dry place. Avoid exposing it to direct sunlight or high temperatures, which could affect the quality of the product.
