How can I get rid of psoriasis scales?

Originally, psoriasis was just red, but

 

Since about last week, suddenly there's been white stuff on the psoriasis?

 

I get silver epilepsy.

 

Other parts aren't like that.

 

It seemed to appear only in the exact spots where I had psoriasis.

 

Is this because my psoriasis has gotten worse?

 

Can I use this for psoriasis exfoliation too?

 

Please recommend some cosmetics that can remove psoriasis scales.

 

Please give me some recommendations from Unnie's Pouch.

 

I'm going shopping...
