Lips have no oil glands and only a very thin keratin layer to prevent moisture loss.
Many lip products, including balms, contain petroleum derivatives which actually draw oil out of the lips. Petroleum products are also easily assimilated into the body over time and can build up in your body tissues. So, we think it's important to look for products with natural oils like vitamin E, castor oil, avocado oil and natural crystals which have small molecules that are easily absorbed into the lips and help to moisturize the tissue. Beeswax and Carnauba wax have larger molecules and form a needed protective barrier against moisture loss and the elements. We recommend Cosmedix's Eye Believe Crystals for the lips and the eyes to keep delicate lip tissue soft and hydrated.
