Thanks for the query. This is a common condition and is unusual and could indicate an insulin resistance. Skin is the mirror of internal health and to get a perfect skin you need to treat both ways - internally and externally. See a Dermatologist who will recommend a product for reducing puffiness and darkness and will advocate the correct method to use it. Avoid rubbing the eyes as it will increase pigmentation. Your Dermatologist may request a few blood tests to understand the blood chemistry and treat them specifically. Now-a-days many chemical peels also offers realistic promise- like glycolic acid and lactic acid peels. Dermapen in combination with mesotherapy also helps. A healthy diet and lifestyle is mandatory to achieve results.
