Hi Thank you for asking HCM I have gone through your query. Psoriasis is a chronic autoimmune disease. But you can achieve proper remission with effective treatment. Applying corticosteroid ad salicylic acid like what you use- Halotoz-s is good. Taking vitamin D supplements is also effective. Avoid soaps and use green gram powder for washing skin. Using coconut oil or liquid paraffin for moisturising skin is also good. Avoid stress , alcohol , cigarettes smoking , using more hot water for bathing etc should be avoided as it can stimulate its occurrence. Hope this may help you. Let me know if anything not clear. Thanks.
