Thank you so much for your question. I’m so sorry to hear that your husband has developed this condition. Psoriasis is an autoimmune disease and is unfortunately not curable. There are quite a few treatment options and some patients find that Coal Tar preparations are very helpful, while others do not get any relief from them. Others find cortisone preparations more helpful. My personal opinion is that you need to treat this on a number of levels to get the best results and to help manage the condition. So here are a few things I think are very helpful: 1) Make sure you are using oral anti-oxidans daily as this slows down cellular mutation. I highly recommend the use of Ovelle tablets (made by Lamelle). 2) Use a lotion that will help to restore the skin’s barrier and help with the itching and irritation and redness. I highly recommend Lamelle’s Serra Restore Cream. 3) Many patients find that exposing the affected area to the sun for 10mins, 3 times per week is very helpful. 4) Make sure you are taking Vit D3 supplements. 5) Follow a healthy eating plan. Stay away from sugars and lots of fats and caffeine. You are going to need to ensure that these become lifestyle changes, and you will find it takes 6-8 weeks to start seeing big differences in the skin’s affected areas. Sincerely hope this is helful to your husband, please do send me another message to let me know how he’s doing.
