Cetaphil Protective Lip Balm SPF 50+ provides very high broad-spectrum UVA and UVB photoprotection while soothing, softening, and conditioning dry, delicate lips. Its lipid-replenishing formula combines photostable chemical UV filters with coconut oil, vitamin E, and a lipid-soluble vitamin C derivative to prevent moisture loss and shield against photo-induced cheilitis and environmental dryness. The smooth emollient stick glides easily across the vermilion border, maintaining barrier hydration without leaving an occlusive, waxy residue. Suitable for daily outdoor exposure, it maintains comfortable, supple lips throughout sustained sunlight exposure.
