The skins of pistachio nuts are packed with antioxidants, and, when this ingredient is applied topically, it can have a photoprotective effect, reducing UVB-induced erythema. More study is needed, though, and anyone with a nut allergy should be careful.

Pistacia vera

The pistachio (/pɪˈstɑːʃiˌ, -ˈstæ-/,Persian: پسته‎‎; Pistacia vera), a member of the cashew family, is a small tree originating from Central Asia and the Middle East. The tree produces seeds that are widely consumed as food.

Pistacia vera often is confused with other species in the genus Pistacia that are also known as pistachio. These other species can be distinguished by their geographic distributions (in the wild) and their seeds which are much smaller and have a soft shell.
