Can skin pigmentation change over time, and if so, why?
Yes, skin pigmentation can change over time due to various factors. Some of the reasons why skin pigmentation may change include:
- Sun exposure: Exposure to UV radiation can cause the skin to produce more melanin, resulting in a darker skin tone or the development of dark spots or hyperpigmentation.
- Aging: As we age, the skin may become thinner and more fragile, which can make blood vessels more visible and result in a duller, uneven skin tone.
- Hormonal changes: Hormonal changes during pregnancy or menopause can cause the skin to produce more melanin, resulting in hyperpigmentation or darkening of the skin.
- Medications: Certain medications, such as antibiotics, anti-inflammatory drugs, or chemotherapy, can cause changes in skin pigmentation.
- Skin trauma: Injuries, scars, or burns can cause the skin to produce more melanin, resulting in hyperpigmentation. Genetics: Changes in skin pigmentation can also be influenced by genetics, such as the development of freckles or birthmarks.
