People never give even a small glance towards the ingredients of any Lip-Balm. It so happens that your lips must be sensitive to some of the following ingredients which make you apply it more frequently. For example Menthol, Phenol and Camphor help in providing a soothing effect to your lips but are potential enough to dry them over time. Salicylic acid helps to exfoliate the dead skin of your lips but might cause irritation. Other ingredients like Lanolin, Benzocaine, paraben and Beeswax can cause allergic reactions.
