It is important to keep your skin well hydrated because plaque psoriasis causes your skin to be very dry and itchy.

Cut the gel capsule on the tip and let the oil ooze from the inside. Apply the oil to the affected areas of skin using a gentle circular motion. This will help in softening and smoothing scaly patches of skin. You can apply the fish oil several times a day until scales have been totally removed. Mild psoriasis on knees and elbows can be treated with a mild emollient, such as emulsifying ointment BP or white, soft paraffin. Both of these substances will minimize scaling and prevent development of cracks on the skin. These are available in many skin and hygiene stores, some grocery stores, and online. Many soaps contain harsh chemicals that can irritate the skin and make psoriasis worse. Therefore, it’s important that you choose hypoallergenic soaps which contain mild ingredients. A mild soap and warm water will help keep your condition from getting worse. Examples of mild soaps include Aveeno cleansing bars, Nivea cream bars, or phisoderm soaps.

Summary:
Apply unscented moisturizers to your skin each day to help fight plaque psoriasis. Apply olive oil to your affected areas. Try applying fish oil to keep your skin moisturized. Try paraffin oils or emulsifying ointment BP. Remember to use mild soaps to keep your skin from getting dry and irritated.
