The skin on our lips is so soft and thin that the blood vessels can be seen through it. That’s what gives our lips their red colour. Our lips don’t have any sebum or sweat glands, which are responsible for supplying our skin with oil and moisture. And the corneal layer, which protects our skin from harmful environmental influences, is very thin on our lips, as well. Our lips are therefore dependent on care and protection from the outside. This is why you should use lip balm, such as Labello Hydro Care, once in a while.
