Why is the area around my eyes brown in colour?

 Hi,   Brown discolouration around the eye may result from constricting blood vessels that cause discolouration or thinning of the skin due to chronic fatigue, eye strains, lack of sleep, allergies, iron deficiency, prolonged sun exposure, dehydration, thyroid dysfunction, hormonal changes, genetics etc. 

Treatment depends on causes. So, you can undergo some investigations like CBC, thyroid function tests etc to find out the exact causes for discolouration and then treat them accordingly.

In the meantime, take proper sleep and maintain sleep hygiene, take plenty of fluids, try to lead a stress-free life, avoid prolonged exposure to sunlight, avoid allergens or irritants like cosmetics, dyes etc.

You can apply cold compresses on your discolouration area for 3-4 times daily. You can also apply cold tea bags to your discoloured area.

Hydroquinone containing cream can be applied along with Hydrocortisone topical cream to the affected discoloured area and take vitamin C enriched foods or supplements.

Peeling of skin, laser therapy etc are the available medical treatment for cosmetic purposes too.

Take care. In case of any other query, knock me.
