It will clear symptoms but not so keen on such a treatment. The psoriasis will return.. Unfortunately psoriasis is not curable at the moment but taking dietary measures will be better for all round health, get plenty morning and late afternoon sunlight, protect skin with coconut oil, not sun block and drink plenty water especially in the summer months. Im still battling a bit with mine but its not as bad, my skin is 75% better I find intermittent fasting also helps.
Abstained from any relationship and socialising for nearly 10yrs ..a divorce during that u was under extreme stress and ended up with cancer. Now I’m ok and phorasis has demmished 90% because I’m stress free loving myself more and healthy eating. But strangely enough I never had psoriasis on my face because it is always exposed to VitD if the sun. VitD is vital.
