All of my adult life I have been plagued by dry, itchy skin on various areas of my body. It goes in cycles. Sometimes the dry and itchy skin will occur on my face or in the crook of my knees or arms. I have been told by a medical professional that I have eczema. Recently, I read some material that stated that fish oil can be helpful in the prevention of eczema. The oil prevents the loss of moisture from skin, leaving it shiny and glowing. I am going to find a source for purchasing fish oil and begin taking it right away.
