Lip balm or lip salve is a wax-like substance applied typically to the lips to moisturize and relieve chapped or dry lips, angular cheilitis, stomatitis, or cold sores. Lip balm often contains beeswax or carnauba wax, camphor, cetyl alcohol, lanolin, paraffin, and petrolatum, among other ingredients. Some varieties contain dyes, flavor, fragrance, phenol, salicylic acid, and sunscreen. The primary purpose of lip balm is to provide an occlusive layer on the lip surface to seal moisture in lips and protect them from external exposure. Dry air, cold temperatures, and wind all have a drying effect on skin by drawing moisture away from the body. Lips are particularly vulnerable because the skin is so thin, and thus they are often the first to present signs of dryness. Occlusive materials like waxes and petroleum jelly prevent moisture loss and maintain lip comfort while flavorings, colorants, sunscreens, and various medicaments can provide additional, specific benefits. Lip balms are produced from bee wax and natural candelilla and carnauba waxes. Lip balm can be applied by a finger to the lips, or in a lipstick-style tube from which it can be applied directly. In 2022, the global lip balm market was valued at US1247.74 mln by 2027. The lip balms are divided into different types by their ingredients: UV filter lip balm. This type of lip balm can be applied all the year round, especially in summer or when staying in a place with an increased solar activity (e.g. mountain ski resorts). Nourishing lip balm. This type works best in winter. Moisturizing lip balm. If you apply this lip balm in winter, your lips can be cracked because the balm is too quick to be absorbed. This type of lip balm is good for dry lips. Moisturizing lip balm can be worn year round. Medicated lip balm. It should be applied with care. It acts as a softening and antiseptic medication. Tinted lip balm. You can wear tinted lip balm year round.
