You might think that a good lip balm is simple, and while it should be easy to use, the formula itself is often a bit complicated. And some lip balms can even make your skin drier than before. Most of us are familiar with the frustration of applying a formula only to reach for it after a few minutes because the skin already feels parched.

A good lip balm should keep your lips moisturized for hours (although some reapplying throughout the day is normal, especially if you drink hot liquids, eat spicy food, or are in dry air). To keep the lips moisturized, it should contain moisturizing, occlusive and emollient substances.

How does this combo work so well? Moisturizers draw in water, emollients help maintain the barrier and repair any cracks in the skin, and occlusives create a protective film on the surface. It’s the perfect combination for a hydrated pout.

While there are many ingredients that are safe to use on the lip area, here are a few of our favorites to look out for. Hyaluronic acid, glycerin, and castor oil can be great moisturizers. Options such as moringa seeds, ceramides, coconut oil, and honey can act as emollients. And shea butter, cocoa butter, and sunflower seed wax are ideal occlusive ingredients.
