Psoriasis There is no cure, it can never be certain that the rash does return. However, there are medical treatments that relieve the intensity of the rash during episodes of psoriasis.

Creams and ointments

Doctors, for example, cortisone creams or retinoids (substances related to vitamin A). A creamy calcipotriol (Dovonex ®), a derivative of vitamin D, is also used to reduce the proliferation of cells in the epidermis. Other options offered in various forms include preparations tar, the petroleum jelly, to anthraline and salicylic acid.

Treatments or phototherapy photochemotherapy

In cases where the psoriasis covers a large part of the body or when the rash is persistent, treatments or phototherapy photochemotherapy may be prescribed. Phototherapy involves exposing the patient to ultraviolet radiation from sunlight or appliances irradiation (UVB rays usually). The photochemotherapy combines exposure to ultraviolet rays to a photosensitizing drug (which sensitizes the skin to the action of these rays). The photochemotherapy called PUVA combines exposure to UV rays with the psoralen. The short term risk of PUVA are negligible, but long-term therapy slightly increase the risk of skin cancer. Some newer technologies can provide exposure to UVB narrow-spectrum, which would be less dangerous. This treatment to UVB can be combined with an application of a photosensitizing, such as tar preparations.
