The skin around your eyes is sensitive and very thin, so it can easily become irritated, red and puffy. There are many factors that can cause "puffy eyes" that includes: 

  • Dehydration - As your body becomes dehydrated it begins to retain water, leading to puffy skin around the eyes. 
  • Environment - Pollutants in the environment cause redness, irritation and puffiness. Using detoxifying products can help alleviate this. 
  • Makeup - Certain makeup has bacteria that can irritate the eye area if left on too long. It's important to carefully remove all makeup at night. 
  • Sun Exposure - Along with aging, the sun also causes the skin around the eyes to lose elasticity and swell. Using an SPF daily to block UVA/UVB rays is essential to reduce damage.
