Drink at least 8 cups of water daily to keep your body, skin, and lips hydrated.
Saliva contains digestive enzymes that can break down lips’ protective barrier and dry them out. Resist the temptation to lick them.
Look for hydrating ingredients such as beeswax, shea butter, vitamin E, and almond, jojoba, or coconut oils in lip balms. Good old petroleum jelly works well too.
Just like face and body exfoliators, ones for your lips that contain fruit-acid-based alpha or beta hydroxy acids slough of dead skin. But if you have sensitive skin or your lips are severely chapped or cracked, use these products not more than once weekly, as they can irritate skin and cause stinging or persistent redness.
One reason matte lipsticks stay put for so long is that they are drying—so if your lips are extremely chapped, use them sparingly.
Hope this helps
