Progesterone, one of the main female sex hormones, can lighten skin. It counteracts the effects of estrogen, which darkens skin. When melanocytes, the cells responsible for skin pigmentation, are exposed to progesterone, they produce less melanin, resulting in a lighter skin tone.
Here are some additional details about how hormones affect skin pigmentation:
- Estrogen: This hormone stimulates melanin production, leading to darker skin.
- Progesterone: This hormone inhibits melanin production, leading to lighter skin.
- Hormonal imbalances: Changes in hormone levels, such as during pregnancy or menopause, can cause skin pigmentation changes, including both darkening and lightening.
While hormones play a significant role in skin pigmentation, other factors also contribute, including sun exposure, genetics, and certain medical conditions.
