Using this lip oil is super easy. Just take a small amount of the lip oil and gently apply it to your lips. You can use it throughout the day to keep your lips moisturized, especially when your lips feel dry. When it comes to storage, keep it in a cool and dry place away from direct sunlight. This will help maintain its quality. As for maintenance, make sure to keep the cap tightly closed after each use to prevent the lip oil from drying out or getting contaminated. Also, if you have any specific skin allergies, check the ingredients list first. If you notice any adverse reactions, stop using it immediately.
