Psoriasis treatment

I have a relative who has a mild case of psoriasis. Since I was young, I knew that she got this condition and it was very stressful for her. The patch grew near her forehead and she covers it with her hair fringes. She also need to use a lot of cream to control the inflammation.

As I grew older, we went our separate ways and I do not know if she has seek any psoriasis treatment. I never find out if that patch eventually grew larger or was it totally controlled.

I do not know much about psoriasis except for that encounter with my relative. However, I know that psoriasis can spread all over the body and even affect the joints.
