Blistex Medicated Lip Balm helps prevent dryness and chapping with an easy glide formula that also soothes irritated lips. Made with three long-lasting protectants and SPF 15 for sun protection, this lip balm is exactly what you need for daily lip care. It seals in lip moisture to prevent drying of lip tissue. Temporarily protects and helps relieve chapped or cracked lips. Apply liberally 15 minutes before sun exposure and reapply at least every two hours. Use a water-resistant sunscreen if swimming or sweating. Ask a doctor before using on children under two years of age. For external use only.
