There are still many ways to thin your lips. For example, you can add more water in your life and get rid of the habit of biting your lips. You can also use makeup to apply lip concealer with similar skin color on the edge of your lips to minimize the scope of lipstick application. Lips can be thinned directly by surgery. There are usually two methods: surgical resection and aspiration, and there is usually a recovery period of about one month after operation. So you should pay attention to eating spicy food and keep it after operation.
