No its not only because of over sun exposure. I never go out in the sun. I work nights and sleep in the day. If I go out in the day I drive to where im going and go straight in and out, and the underneath of my eyes are snow white. It would be nice to find out facts from doctors rather then opinions and guesses.
Hello,
This can be due to overexposure of the face to the sun which may less affect the area above the cheeks. Take rest adequately and eat healthy nutritious food containing lots of green vegetables. Try to avoid caffeine, because it promotes water retention and leads to the dryness of the eye.He should also apply almond oil or skin creams containing vit C or K,alpha hydroxyl acids and kinetin. Also avoid the sun for some days or wear sunscreen half an hour before going out in sun.
If the symptoms persist then please consult a dermatologist. I hope it helps. Take care and regards.
