Skin What Causes

1. Genetics

Genetics play a significant role in determining skin tone. People with darker skin tones tend to have more melanin, a pigment that gives skin its color. Melanin production is controlled by genes, and people who inherit genes for higher melanin production will have darker skin.

2. Sun exposure

Sun exposure is another major factor that affects skin tone. When the skin is exposed to sunlight, it produces melanin to protect itself from the sun's ultraviolet (UV) radiation. This can cause the skin to darken. People who spend a lot of time in the sun or who live in sunny climates tend to have darker skin tones.

3. Hormones

Hormones can also affect skin tone. For example, women who are pregnant or taking birth control pills may experience darkening of the skin around the nipples, areolas, and genitals. This is due to the increased levels of estrogen and progesterone, which stimulate melanin production.

4. Medical conditions

Certain medical conditions can also cause changes in skin tone. For example, Addison's disease, which is a disorder of the adrenal glands, can cause the skin to darken. Pituitary gland disorders can also lead to changes in skin tone.

5. Medications

Some medications can cause changes in skin tone as a side effect. For example, antimalarial drugs can cause the skin to darken, while chemotherapy drugs can cause the skin to lighten.

6. Artificial tanning

Artificial tanning, such as using tanning beds or spray tans, can also cause the skin to darken. However, it is important to note that artificial tanning can also damage the skin and increase the risk of skin cancer.
