Disseminated superficial actinic porokeratosis - treatment?

I suffer from disseminated superficial actinic porokeratosis and wonder if there is anything that I can use to improve the appearance of affected areas on my skin.

DSAP (disseminated superficial actinic porokeratosis) is an inherited skin condition that principally affects the arms and legs. It is inherited as an autosomal dominant characteristic, which means that there is a 50% chance that the children of an affected person will also have the condition. The lesions are approximately 1.5 mm in diameter and they develop as a result of exposure to sunlight. Sometimes they can be quite itchy. People who live in sunny climates tend to have many more lesions than people who live in less sunny places. I regret to say that treatment of DSAP is not very satisfactory. Various creams have been used including various vitamin enriched creams but no one treatment has proved to be very effective. Some people have been treated with cryotherapy with varying degrees of success and return for further treatments when the lesions return. Sunscreens can be helpful in preventing the eruption of further lesions on the skin.
