Sitting long time infront of laptop screen may cause face redness and dryness ? wt should i do to prevent it ?

Laptop Use : I am not aware of any studies that purport to link extended laptop use with facial dryness and redness. The symptoms are more likely due to the environmental conditions at work - maybe a hot desk lamp, sun exposure through the window, etc. Review your surroundings carefully and try to isolate the culprit. There are many skin moisturizers that can address your dryness in the meantime.
