Melvita

Nigella oil has been considered a universal remedy since the time of the Pharaohs — the Prophet Mohammed said of the stuff, "it cures everything but death." While its uses extend to toning the scalp, reducing redness of cuts and scrapes, and relieving muscle tension, nigella oil is particularly well-suited to the purification of oily and combination skin. I don't know how it works; it just does, making pores smaller, tighter, and cleaner and reducing daily oil production over time. It has a strong but not unpleasant spicy herbal fragrance, so cut it with a bit of a fragrance-free carrier oil like hazelnut or jojoba. Also, all of Melvita's oils are wonderful and reasonably priced. And Marion Cotillard uses them. Whatever. [$21, Melvita]
