Dark lips can be caused by a variety of factors, including genetics, lifestyle habits, and certain medical conditions. But there are several home remedies that can help you treat dark lips. Here are a few tips that you can follow to overcome this issue.
Lemon Juice: Lemon is a natural bleaching agent and can help to lighten dark lips. Apply some lemon juice on your lips and leave it on for about 15 minutes before rinsing it off with water. Do this daily for best results.

Sugar Scrub: Mix some sugar with olive oil or honey to make a scrub. Gently massage this on your lips for a few minutes and then rinse it off. This will help to exfoliate your lips and remove dead skin cells that can cause darkening.
Beetroot Juice: Beetroot is rich in antioxidants and can help to lighten dark lips. Simply apply some beetroot juice on your lips before going to bed and leave it on overnight. Rinse it off in the morning.

Cucumber: Cucumber has cooling and lightening properties that can help to reduce pigmentation on your lips. Cut a cucumber into slices and rub them on your lips for a few minutes. Leave it on for about 10 minutes before rinsing it off with water.
