Sleeplessness and iron deficiency can cause dark circles; and in such cases, adequate rest and plenty of iron-rich foods and supplements are enough. But sometimes, dark circles can be resilient and refuse to go away. If you find your dark circles not receding, no matter how much supplements you take and rest you get, chances are they are caused by hyper pigmentation.
What is Pigmentation?
When patches of skin darken due to excessive melanin (a skin pigment) production, it is called pigmentation. Common manifestations of pigmentation are freckles, age spots, brown spots and, most primarily dark circles. The causes of pigmentation include:
1. Sun exposure- age spots are caused by sun exposure, especially in older skin
2. Scarring- acne, burns or abrasions can cause scarring, which darkens the skin
3. Genetics- freckles are genetic, and factors such as hormones or sun exposure can worsen them
4. Pregnancy- patches of skin on the face or abdomen darken during pregnancy
The most common method to treat pigmentation caused dark circles is hydroquinone, which is an ingredient that lightens skin. When hydroquinone is used in creams, it takes a long time for it to come into effect. Dark circles may take a long time to completely fade away.
