Question

are lips and skin is made up of same material ?if yes then why are they in different colors?​

Answer 1

Answer:

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

Answer 2

Answer:

With light skin color, the lip skin contains fewer melanocytes (cells which produce melanin pigment, which give skin its color). Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. ... The lip skin is not hairy and does not have sweat glands.
