-Topical corticosteroids (steroids) are very useful and often first line treatment for limited or small areas of psoriasis. These come in many preparations including sprays, liquid, creams, gels, ointments, and mousses. Steroids come in many different strengths; stronger ones are used for elbows, knees, and tougher skin areas while milder ones are used for areas like the face, underarms, and groin. These are usually applied once or twice a day to affected skin areas.

He added that there were medical as well as aesthetic reasons for having a generous foreskin:

The light source needs to be directly applied to the target tissue for a specific amount of time. For surface skin treatments, the light is easily directly applied to the area of the skin where the photosensitizer drug has been applied ( such as face, scalp, arms, etc.).
For internal cancers, delivering the light to the desired area is more challenging. The light may be delivered through small fiber optic cables into the body cavity or area being treated. Sometimes endoscopes ( a thin lighted elongated tube which is inserted into a body space) are used to deliver the light into the lungs, stomach, or bladder.

They can be found on any skin surface including the scalp and back of the hands.

Your decision on the best treatment choice may depend on different factors such as the location and type of skin lesions, your past treatments, your overall health, and level of comfort.

• For moderate to severe disease that involves much larger areas of the body (like 20% or more of the total skin surface) topical products may not be effective or practical to apply. These cases may require systemic or total body treatments such as pills, light treatments, or injections. Stronger medications usually have greater associated possible risks.

• For mild disease that involves only small areas of the body (like less than 10% of the total skin surface), topical (skin applied) creams, lotions, and sprays may be very effective and safe to use. Occasionally, a small local injection of steroids directly into a tough or resistant isolated psoriasis plaque may be helpful.
