Freckles are not caused by a deficiency. They are caused by increased melanin production in certain areas of the skin, often triggered by sun exposure.
Freckles are small, flat, brown spots that appear on the skin, particularly in people with fair skin. The increased melanin production in these areas is a natural response to protect the skin from harmful UV rays.
While freckles are often associated with sun exposure, they can also be inherited. If your parents have freckles, you are more likely to have them as well.
Freckles are not harmful and are considered a normal part of skin pigmentation. They are not caused by any specific nutrient deficiency.
