The thickness of the lower lip is usually caused by congenital factors. The body can put the middle finger and forefinger on the upper lip with a little force, and then gently press them, so as to exercise the lip muscles and make them thinner. In addition, it can be improved by plastic surgery. Don't pout or hang your mouth at ordinary times.
At the same time protect your lips. After we get up every morning, we should wet the cotton pad to wipe our lips and around the corners of our mouths. In this way, we can clean up the stolen goods left last night. Then, wet the cotton pad with lotion and apply it to your lips for about 30 seconds, so that you can replenish moisture to your lips. Many people think that lip balm is only needed in winter, but it is not. We can usually put a layer of lip balm on our lips to keep them moist.
