A tube of lip balm is a common product used to relieve dry, cracked lips. It works by forming a protective layer on the skin that shields the lips from harsh weather conditions, such as cold winds and dry indoor air, especially during winter. According to dermatologists, lip balm helps lock in moisture and prevents the lips from drying out. However, certain ingredients, like flavoring additives and lanolin, may cause irritation for some people. This is why many in colder regions rely on lip balm to keep their lips soft and hydrated. Manufacturers have worked to create formulas that minimize environmental damage. With advances in technology, improved ingredients are now included to better retain moisture. Experts suggest that those with sensitive skin use fragrance-free, petroleum-based lip balms, as they are often the safest option. These products undergo testing to meet strict quality standards. Studies have confirmed that the natural barrier provided by lip balm plays a key role in protecting the skin. Today, lip balm comes in many forms, and research aims to boost its benefits while reducing allergic reactions.
