The skin on our lips is thin and always exposed to the elements. Using the antiviral and antibacterial properties of lysine and ETTO medicinal grade Tea Tree oil, The Lip Shield is ideal for anyone who experiences cold sores. Customers have raved they haven't had a cold sore since using The Lip Shield! A hit of zinc helps defend lips from sun damage as well. The Skin Balm with Tea Tree is a wonderful option for lips too, especially as an overnight lip mask for luscious, hydrated lips when you wake up! Made without petroleum & mineral oils.
