Medicines applied directly to the skin are often called topical treatments or just 'topicals'. They come in the form of ointments, creams, lotions, gels and shampoos.

Topicals may contain coal tar, vitamin D-derived products, steroids or a combination of different treatments.

Topicals can be used alongside all other treatments for psoriasis and you might need to use a topical as a ‘top up’ to control your skin condition.

Coal tar products

Coal tar products have been used for many years. They help to slow down the rate at which skin cells are replaced. This may help reduce itchiness and flakiness.

Some people like and respond well to coal tar products, especially the shampoos but can be put off by the smell and messiness of them.

Topical steroids

Topical steroids (steroid creams or ointments) are often prescribed for psoriasis. You may be prescribed different strength steroids over a period of time or for different parts of your body.

Please take a look at the topical steroids section to learn more.

Topical calcineurin inhibitors

Topical calcineurin inhibitors, for example tacrolimus or pimecrolimus, act on the immune system by blocking one of the chemicals called calcineurin that causes redness and inflammation of the skin. They are particularly suitable for delicate areas of skin such as the face, skin folds and outer genital skin, where prolonged treatment with topical steroids may not be appropriate.

You may experience a mild burning sensation after the first few applications, but this tends to settle down within a week. They do not contain steroids and can be used with emollients.

Topical vitamin D derivatives

Vitamin D derivatives, for example calcipotriol, are a common and effective topical treatment for psoriasis. They help by slowing down the rate skin cells are replaced.

A fixed combination of vitamin D derivative and a steroid is available as a gel, cream, lotion or foam spray.
