The skin around your eyes is generally the first bit of your body to show the world how old you are.  The skin here is three times thinner than the rest of your face and has fewer hydrating glands, so it needs to be treated with care and respect. 

Bad habits and fluid retention cause eyebags, but a mini-detox and cold compresses will ease them.  If you wake up with eye bloat, a brisk walk in the fresh air and a large glass of water will help dislodge fluid and toxins. 

Dark circles can be hereditary, but you should also look at your lifestyle.  The skin around the eye is thin, which makes it vulnerable to external irritants such as smoke and other factors like lack of sleep.  Irritation in the area leads to dilation and leakage of red blood cells, which can accumulate and stagnate, swell and appear darker through this thin skin. 

There's nothing funny about laughter lines, which are a result of your genes and your lifestyle.  The former you can't do much about but lifestyle factors, especially sun exposure, can be controlled.
