Hyperpigmentation on lips
Hyperpigmentation of the skin is when a portion of the skin is darker than the other surrounding areas. This occurs due to melanin. Melanin is the pigment that is produced by cells called melanocytes. Melanin gives the skin its color. When the skin produces more melanin, it leads to hyperpigmentation.
Why are lips differently colored than regular skin?
Normally, skin is composed of numerous layers of cells, however, the lips only have 3 to 5 cell layers. This means that skin over lips is thinner. Lips are also richly supplied by blood capillaries. Due to this, lips show the color of blood capillaries beneath them, owing to their crimson or pinkish color.
Why are some lips darker than the others?
The lips come in a variety of colors and shades. Some people have lips with a more pinkish tone, whereas others have them more in a purplish – or even olive – tone. It all boils down to genetics and race. Those who are fair-complexioned tend to have rosy lips whereas those with darker skin have purplish lips. However, this is not a sure shot rule.
Cigarettes contain various toxins that can harm your health, leading to conditions ranging from emphysema to cancers. smoking can also affect the lip color. People who smoke regularly have hyperpigmented lips. Nicotine is the main culprit.
