Our new slim fit tube - lower profile is more comfortable and resists unscrewing in your pocket. Less Beeswax means it soaks into your lips without leaving that goopy residue. Powerful moisturizers to replenish chapped lips. Many of the sun protection factor (SPF) ingredients found on the market today are composed of potentially harsh chemicals that can actually contribute to chapped lips. We suggest the use of SPF only when out in the sun. The active SPF ingredient in Mountain Mint, methoxycinnamate, is derived from cinnamon and natural benzoin gum - it is the best choice to protect without chapping.
