It is quiet common nowadays to have dark circles around your eyes. There could be many reasons behind them. These could be due to less sleep, sitting in front of a desktop/laptop for longer hours, use of cosmetics, which are not suitable for your skin type (could also cause itching or irritation or even an eye infection at times for some) or even because of drinking habits. It has always been said that prevention is better than cure. So, people should ideally try to work on the aforesaid things to avoid these, such as taking proper sleep, taking regular intervals while working on a computer, by using only those cosmetics which are suitable for skin type else changing them immediately.
Puffy eyes, just like dark circles, are a kind of swelling around eyes and could be due to skin allergies, dehydration, some disorders or even dermatitis, and retention of fluid being another. For some people, it could also be in their genes. Some people may relate general swelling around eyes to puffy eyes but swelling is not a cause for these though a doctor should be consulted nevertheless.
Not everything that we see in market as a cure is effective. Some of these products could be fake while others may work for some, but not for all.
There are many prevention methods which we can practice in our day to day life to avoid puffy eyes, taking into consideration that the levels of effectiveness may again vary from person to person.
1) While sleeping, use a pillow or something else to keep your head a bit elevated.
2) Place an ice-pack or a thick piece of cucumber on eyes for relief which, in turn, are also considered effective to reduce the swelling. A gel mask can also be considered as an alternative.
3) Anything that you apply on skin such as facial creams, gels, should be stored in a cool place such as a refrigerator.
4) Beauty products that are based on water are better for skin than oil based products.
5) If you feel itching in eyes or the skin around the eyes turn red, it could be because of allergy. Change the skin product you are using immediately.
If none of these treatments are working for you, consult a doctor to determine the severity of puffy eyes. If nothing works for you, you may consider going for a surgery (though you should consider the risks involved in it too, as eyes are a very sensitive organ). This surgery can be called as Blepharoplasty in which surplus tissues from around the eyes are removed. But it is advisable to consider this surgery only if necessary.
