You are suffering from chronic cheilitis causing this.. Medicine available for good improvement...... Do direct online consultation for detailed prescription.

You are having cheilitis, which is the inflammation of the lips. You are probably having a lot of dryness because of which you lick your lips to moisten them. Saliva dries out your lips as it has enzymes which break down the skin proteins and cause a defective skin barrier. Because of this, you are having the redness and irritation. Use of lipsticks/lip glosses also tends to make it worse and until you recover from this, I would recommend you don't use any cosmetics over the area. You need to use a colourless, bland lip balm (with SPF) regularly - after washing the face, after every meal and before sleeping. You also require a cream to bring down the inflammation. Do consult me online and I will help you out.
