Psoriasis is a chronic, recurring condition that commonly causes red scaly patches to appear on the skin. These patches frequently occur on the elbows and knees, but can affect any area including the fingernails and toenails.
The best protection against psoriasis flare-ups is to keep the skin as healthy as possible. Use moisturizers twice a day. Wear cotton against the skin. Clean heating ducts and remove surface dust regularly. Develop habits that maintain your overall health, including wise food choices and sufficient rest. When the body is tired, the immune system is compromised, causing the psoriasis to flare.
