What causes acne redness? Acne is a common facial skin disorder caused by the blockages in the oil glands.
These blockages fill up with bacteria over time and eventually develop in to pimple like spots or bumps giving a "reddish" complexion effect to the skin.
The redness is the most visible affect of the acne condition, especially for people with fairer skin, and can often be a source of embarrassment especially during puberty.
There are steps that you can take to reduce the reddish affect of the acne, these include:

• Washing your face with cool or cold water as oppose to warm or hot water.
  Warmer temperatures can irritate the skin and cause more redness.
  
• Apply something cool to the affected areas to try and reduce swelling and inflammation.
  Examples of good things to use are; a damp washcloth that is put in the freezer for twenty minutes to half an hour or a paper towel filled with crushed ice.
  
• Cut open a fresh aloe vera plant and rub the gel over the affected area.
  
• Cut up some fresh cucumber into slices and place them on the affected areas for ten to twenty minutes.
  
• Avoid using any make up with many synthetic chemicals.
  Some of these contain oils that can block the pores, increase the bacteria and eventually increase the acne itself.
  
• Try applying eye drops to the affected area.
  The same ingredients that can relieve redness in the eyes can also be used to help the skin.
