Your lips generally lose out on their natural pink colour and become dry due to exposure to sunrays, dust or pollution.
To treat your lips from being dry, chapped, all you need to do is some ghee. To use, warm some ghee and apply it on your lips before you going to bed. Once you wake up, scrub your lips with dry flakes and see the results for yourself. Repeat the process every day to get soft and pink lips naturally.
