Lemon Juice

[Spirulina]

Hi, I have read an article that citric acid in lemon juice can ease dryness and flaking in psoriasis — apparently it helps the skin retain water and encourages the exfoliation of dead skin cells. The juice of a lemon contains psoralens, a natural chemical found in many plants which is highly sensitive to the sun’s UVA rays and reacts on the skin’s cells. I was wondering whether any one had used this form of treatment? Please let me know if you have.
