Hello! I was wondering what could be causing my chronicically fissured, cracked and extremely dry lips. My lower are the worst of it all with what seems to be permanent split or crack on my lower right lip and recently both my upper and lower lips are so parched and cracked. I am in both Menopausal and post Menopausal stage. Also could Thyroid deficiencies and hypothyroidism cause this? This has been on for a short time, only about 9 months time, I never ever had this problem before? I have cared for them holistically and naturally, yet these days nothing works! Thank you very much indeed!
