All sunscreens contain ingredients to block the sun’s UV rays. Most lip SPF’s contain either Oxybenzone or some sort of Octisalates. It is well known that these chemicals may cause allergic reactions, (Fisher’s Contact Dermatitis, Fouth Edition chapter 23), and make your lips much worse.
Dr. Dan’s Sun SPF has no such chemicals; instead we use two natural, inert minerals called Titanium dioxide and Zinc Dioxide. These minerals act like tiny mirrors and reflect the UV rays back away from you lips. These tiny protectors are slightly white, which is why Dr. Dan says if your lips are a little white, they will be alright! In addition, our natural yellow wax and chemical-free base with the antioxidant Vitamin E combine to create the perfect moisturizing combination.
