There are various types of treatment for psoriasis. Your doctor will decide which one is right for you. Ointments are usually helpful, except during the summer when your skin may get very warm and sweaty, causing the ointment to rub off. Ointments can also be messy and unattractive. Creams aren't as thick as ointments and can be rubbed into the skin so that they don't show.
Solutions are clear liquids that are especially useful for treating the scalp.
You should apply the medicine at least 2 times a day. Since the medicine is absorbed better through damp skin, putting it on after a shower or a bath is helpful. If you have psoriasis on your scalp, the medicine should be applied after shampooing. Lotion can be used on your skin as often as you like. Body lotion will help to keep the moisture in your skin and remove the scales.
