Question

4. In the winter a of people put a waxy layer of chapstick on their lips, ? Explain your answer by discussing the structure of the skin differs between our lips and the rest of the face .

Answer 1

The skin on your lips is different from the rest of your body because it is thinner and more delicate. Skin on your face can be up to 16 cell layers thick while the skin on your lips is only 3 to 5 layers thick. This means your blood vessels are more apparent, giving your lips their pink or red colour. ……. Another explanation is: The skin on our lips looks clearly different from the rest of our body. That is because it is much thinner in comparison. Skin usually has three separate layers – the stratum corneum, the epidermis and the dermis. The protective stratum corneum is the outer layer that we can see, the epidermis is the layer of skin underneath it, and the dermis is the lowermost layer. The cells of the stratum corneum are basically dead, and they protect the body from the harsh outer environment. The epidermis is mostly responsible for producing new cells. Melanocytes, the cells that produce melanin are also found in the epidermis. Melanin, as you might know, is the pigment that gives us our particular skin color once it is exposed to the sun.

Lips, however, are devoid of melanocytes, so there is no melanin to mask the red color of the blood vessels that crowd the dermis. The dermis is especially visible when it comes to lips because the stratum corneum here is extremely thin. (I hope this information helps you formulate a good response )
