There are many causes of dark circles under the eyes, days of stress and sleeplessness and working for hours on the computer and when you are not working on the computer youngsters are now staring at the mobile all this causes a tremendous amount of eye strain which manifest dark circle under the eyes. The other common causes are dehydration where you are not drinking enough water, anemia where there is enough less blood because of poor eating habit, thyroid disorders which is a hormonal imbalance which would also be looking at dark circles. Most commonly when a young person comes to me with dark circles the first questions that I will ask them is how many hours of sleep are you getting if they are getting adequate 8 hours of sleep, if they are not staring at a computer or at a TV or if they are not being hydrated enough I definitely want to know what is the hemoglobin what is the thyroid and are they eating healthy enough. In spite of all these things if they do have an allergy or a condition which their nose is always blocked that could also be causing a secondary hypo pigmentation of the eyes because the eye strain through the nose. So when your eyes nose is constantly stuffed or your nose is constantly blocked the eyes tend to look a little bit more puffy or dark. The conditions where we see a lot of dark circles is people using unnecessary harsh makeup remover or constantly rubbing their eyes because they having in any kind of allergy problems, so use a gently makeup remover and avoid rubbing your eyes instead moisturize your eyes very gently and very fatty movements not very hard rubbing moments so that the skin is very delicate in this area does not get stress. The most important thing is that if you have a hereditary history of dark circles if your parents has significant dark circles and if your brother or sister have dark circles, you might also be prone to having this dark circles and in this how do you identify that you have hereditary dark circles is that the upper eyelids also pigment when you have acquired dark circles that if you did not have dark circles when you're younger but you got them when you are older the upper eyelid does not get pigment at upper eyelid is free of pigmentation. So, how do you identify how do you treat all these dark circles I think the first and most important thing is find out why you are having a dark circles. Start eating regularly on time, drink plenty of water, take adequate rest in spite of it you feel that the dark circles are increasing then i think that it is time to go with a dermatologist to find out what is the cause of dark circles, we also see eyes under area is the first area in a body to show the aging changes so we see it coming up earlier and earlier we see premature aging in people because of stress, pollution and smoking habits, in this way I think that you have to realize that as soon as this eye area show changes that means the aging has already started, so it's like a warning so that you can start making a antiaging changes which are mostly life style changes. They are not something that you have to take a medicine or product cream for that area. The third thing that I would like to tell you is a quick depth to under eye dark circle before you head out for the party is take a used green tea bag and keep it in the fridge don't throw it away and just for a party use the green tea bag as a mask on your under the area for at least 10 to 15 minutes the cooling of the green tea pack as well as the bio flavonoids which are there in the green tea act as antioxidants the lighting the dark circle as well as they take away the puffiness in the under area.
