What should you know about zinc psoriasis?

Psoriasis is an inflammatory skin condition that can produce raised, red or darker patches with a dry, scaly surface. Zinc is a mineral used by the body for several processes, including maintaining skin and supporting immune function. That role does not show that taking extra zinc will control psoriasis. A cream containing zinc may feel soothing or form a protective layer on irritated skin, while a supplement may be considered only when a clinician identifies a nutritional reason to use it. Psoriasis itself is not diagnosed from a zinc level, and peeling or scaling can have other causes.

Keep a record of where the patches appear, whether they itch or crack, and what products seem to trigger or calm them. Use the psoriasis treatment prescribed for you and apply a plain moisturiser regularly to reduce dryness. Do not start high-dose zinc, combine several zinc products, or apply a new medicated cream over extensive skin without professional advice. Excess zinc can interfere with other nutrients and medicines. If your concern is mainly dry or irritated skin, you can read about Dry Skin, Itchy Skin, Cracked Skin, Peeling Skin, Skin Rash, Skin Redness, or Scaly Skin.

Arrange a dermatology review if patches are spreading, repeatedly cracking, affecting sleep, or not settling with your existing plan. Seek prompt medical care for rapidly worsening redness, warmth, swelling, pus, fever, severe pain, or widespread blistering. Painful red skin over much of the body, or a sudden change involving the eyes, needs urgent assessment. A clinician can distinguish psoriasis from infection, eczema, allergy, or another inflammatory condition and decide whether zinc has any role for you.

Could this be psoriasis or another cause of scaling? Do I have a reason to check or supplement zinc? Which zinc-containing products are suitable for my skin, and which should I avoid with my medicines? What should I use when a plaque cracks or becomes painful?
