Use a lip exfoliator or a toothbrush to exfoliate your lips. It will help you remove flakes and increase blood circulation, making your lips rosy. It will also give your lips a brief plumping effect. Because your lips are more delicate than the rest of your body's skin, proceed with caution. You don't want to overdo it by scrubbing your lips too hard! As for natural ways to change your lip shape, you can try out these recipes or items: eat more berries, drink more water, use a straw when you sip your tea or coffee, chew sugarcane, or eat potato chips (but only if you really like how they taste!). There is no way around it- changing your lip shape requires either plastic surgery or dentistry. If you go the natural surgery/dentistry route, then your options are limited. However, there are things you can do to make your lips look fuller and healthier.
