London: Freckles are small, harmless marks that appear on the skin. Genetics and sun exposure are the primary causes of freckles. Some people are more likely to get freckles than others, depending on their genes and skin type. If a person is genetically more likely to develop freckles, exposure to sunlight can make them appear.
Freckles are common in children and may disappear or become less noticeable as they grow up. In this article, we look at what causes freckles.
Freckles Causes and Treatment
How to distinguish them from other similar marks, ways to remove or lighten them, and when to see a doctor or a skin doctor called a dermatologist.
What causes freckles?
Freckles appear when melanin, the pigment that gives skin its color, builds up under the skin. Freckles may look brown, red, or tan. Sun exposure and genetic factors make some people more likely to develop freckles:
A person’s skin cells produce extra melanin to protect the skin from sun damage. This is why freckles tend to appear after sun exposure.
Freckles can appear over a large area of skin and can reappear or become darker in the summer months. Freckles often fade or disappear in the winter months, when new skin cells replace old cells.
Genetics also plays a leading role in who is more likely to develop freckles based on which type of melanin their body produces.
The body can produce two types of melanin called pheomelanin and eumelanin. Eumelanin protects the skin from UV rays, but pheomelanin does not.
Freckles are harmless marks on the skin caused by genetics and exposure to sunlight. If people have freckles, they will need to take extra care of their skin in the sun.
If people have any concerns about any new marks or changes to their skin, they should see a doctor or dermatologist who can check the skin for anything unusual. (medicalnewstoday)
