It's a common beauty myth that honey can plump your lips, but unfortunately, it's just not true. Honey is a humectant, meaning it draws moisture from the environment and helps to keep skin hydrated. But since lips don't have any sweat or sebaceous glands to produce their own natural moisture, they rely on external sources like balms and glosses to keep them hydrated. So while honey may help to temporarily moisturize your lips, it won't actually make them any fuller or plumper in the long run.
