Dark spots on lips can be a result of many different factors, the most common being smoking and overexposure to the sun. Another common cause is a vitamin B deficiency. These dark spots do not pose a risk to your health, but many people want to get rid of them for beauty reasons.
Things You'll Need
Rub the inside of a lemon on your lips. Lemons naturally lighten skin color without causing harm to the skin.
Mix 1 tsp. honey with 1 tsp. lemon. Apply this to your lips every night. Sleep with the mixture on your lips for best results.
Drink at least 10 cups of water a day to keep your lips from becoming dry. If your lips are hydrated, they will absorb the bleaching property of the lemon more effectively. Hydrated lips are also less likely to become damaged.
Take a vitamin B supplement. If you notice a quick reduction of the dark spots after taking this, the cause was a vitamin B deficiency.
Continue following all of these steps daily until the dark spots vanish.
