One of the most common problems, especially in winter, is dry lips. Getting a lip balm from the nearest pharmacy or store is not always the best choice, as you may have thought.

"Chronically dry lips can be the result of a dry climate, accumulation of dry skin on the lips, or insufficient water and lack of hydration," says Charlene Valledor, a cosmetic chemist. "They may also be the result of an allergic reaction to the ingredients in the lip balms you are using. Many people are actually allergic to some of the seemingly 'good' ingredients in many balms, such as lanolin, beeswax and oil. of coconut.

In fact, dry lips can be caused by everything from weather, skin care products to your diet. Valledor says dry lips can also be a result of vitamin B deficiency.

"Additional factors can also lead to chapped lips, such as allergies to ingredients or foods, certain medications you use, certain medical disorders such as thyroid or autoimmune diseases, perfumes on lip balms, and even just constant licking of the lips." can help dry and crack your lips, ”adds David Petrillo, a beauty chemist, CEO and founder of Perfect Image.

Petrillo recommends products with ingredients such as castor oil, shea butter, or avocado oil. Try a silicone-based balm. However do not overdo it with lip balm. Petrillo says overdoing it with moisture-blocking balms can cause the body to stop "trying to hydrate itself naturally", encouraging the skin to depend on the product, rather than its own process.
