Brief Answer:
Regarding psoriasis

Detailed Answer:
Hello and welcome to ask a doctor service. I have gone through your query and noted your concern.

There are various treatment options for psoriasis depending on the severity or the percentage of body surface area involved which includes topicals like steroid creams, vitamin D analogues like calcitriol or calcipotriol cream, salicylic acid ointments etc as well as systemic remedies like methotrexate, cyclosporin, phototherapy and biological therapies. However, none of the remedies available currently ensure that the disease would never come back. Nevertheless, maintenance treatment with biologics can prevent a relapse in those who are wiling to continue them for long.

Hope I have answered your query.Let me know if you need any more assistance.
