01Moisturise your lips

If you find yourself constantly biting your dry and chapped lips to remove the dead skin, keep your lips well moisturised to prevent dryness in the first place. And instead of using a flavoured lip balm, use a flavourless one like the Vaseline Lip Therapy Color & Care Chapstick – Original as it won't tempt you to lick your lips, keeping them nourished for a long time.
02Exfoliate your lips

Just like the rest of your body, the skin on your lips also sheds dead skin cells. Thus, it's necessary to exfoliate the lips to keep them soft and supple. Gently scrubbing your lips with a sugar and olive oil mix can do the trick.
03Identify your trigger

Take note of situations that cause you to bite your lips more often. If you tend to bite your lips when you're stressed or anxious, try to take your mind off things by going for a walk, talking to someone you trust or taking part in a fun activity. Sometimes, deep breathing exercises, meditation and yoga can help too.
04Seek professional help

If all of the above fail to prevent you from biting your lips, it's best to seek professional help. Depending on the seriousness of the problem, the doctor might suggest behavioural therapy to change the subconscious behaviours.
