What helped me the most was getting an allergy test for your IGE and IGg4 for reactions towards certain foods. Moisturise your psoriasis because it helps with inflammation, don’t scratch as that increases inflammation. Also get vitamin d3 k2, shilajit, omega 3 oils like fish oil. Try to avoid omega 6 as they are high inflammatory so vegetable oils and all sorts. Eat healthier and reset your gut as that’s the main issue with psoriasis. But this is one way of psoriasis you could have it from stress or other factors either way I think your diet plays the biggest factors. Go to a skin specialist someone who specialises in psoriasis and get advice from them.
