People affected by psoriasis should use plenty of moisturizers, mild soaps or soap substitutes that are gentle on the skin, recommends WebMD. Over-the-counter corticosteroids may work better in alternation with calcipotriene, a type of vitamin D. A doctor may also recommend using the cream under a hydrocolloid occlusion, a type of dressing that bonds to the cream, maintains moisture and can remain in place for several days. Light therapy for the hands may involve UVB, PUVA or targeted laser treatment along with the retinoid medication. PUVA includes the medication psolaren, which comes in an oral form and a topical form.
If the psoriasis affects the nails, a doctor may treat it with corticosteroid injections to the nail beds. Psoriasis on the nails can cause fungal infection, so an anti-fungal agent may be necessary in addition to the psoriasis treatments, explains WebMD.Learn more about Skin Conditions
