Dermazinc is our go to for itching, flaking, and scaling. The difference here is the form of zinc and the delivery vehicle. Think of diaper rash cream which is usually 10-20% zinc oxide to clear up diaper rash in a few days. This is Zinc Pyrithione 0.25% which absorbs much better instead of creating the Zinc Oxide barrier that just treats the outer layer. Give this a shot and you won't forget it. Optimal results after three times a day for 7-10 days then daily for prevention.
