and scaling come back and it bothers me but because I have been using this stuff for years, will it have an affect on my system in some way? I don't use much but I have to use it or dermatop every day to control it.
psoriasis is usually treated more conservatively compared to psoriatic lesions in other areas. Usually a mild or weakly potent steroid cream is used since the more potent ones may cause skin thinning or scarring.
In your case, I suggest that you maintain close follow up with your physician. Each patient has varying response to the medication . Steroid use should always warrant close supervision and periodic assessment. Your medication may need to be evaluated and modified.
For penile psoriasis , it seems that mildly potent steroids are the mainstay for therapy. UV therapy entails a lot of risks and other topical medications may aggravate the condition.
