Why is propolis used in a lip balm, and what does it do?

Propolis is a resin-like substance that bees collect from tree buds and sap flows. They use it to seal and protect their hive. In traditional use, it has long been valued for its protective properties. In cosmetic formulas like this lip balm, propolis extract is included not for nutritional value, but for its potential effect on the skin's surface.

The balm's primary function is to form a light protective layer that helps reduce moisture loss from the lips. Propolis is added as an extra element because it is appreciated for helping to calm the feeling of irritation and create a more settled, less reactive sensation on delicate skin. When lips are exposed to wind, cold, dry indoor air, or frequent licking, the surface barrier can become compromised. The balm texture provides physical shielding, while the propolis is intended to add a soothing quality to that protection, making the lips feel less irritated and more comfortable.
