Is applying pyrithione zinc after redness on the face, because of the sun, a bad idea?

Zinc pyrithione: is a zinc complex that inhibits both fungal and bacterial growth. It is principally used as an ingredient in anti-dandruff and seborrheic dermatitis preparations. I don't think it would be of particular help in sunburn...in fact, it is possible it might aggravate an already inflamed skin. I wouldn't use it as a treatment for sun burn. Stay well:)
