The hot dry weather is most likely making it worse. You will need to use a lip balm every two hours. Apply the lip balm after clicking your lips. Applying on dry lips won't be very effective. Alternately apply a little water on your lips to make them wet before applying the lip balm if you don't want to lick your lips before applying the balm. Avoid cheap cosmetic lip balms as they contain agents that peel the skin. Using plain petroleum jelly is advisable if you do not want to spend too much money on a lip balm. Lol balms available in medical stores usually do not contain agents that peel your skin. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore
