Argan oil is celebrated for its skin-nourishing properties. It’s also hugely expensive when bought outside Morocco, so this cosmetic wonder is pretty much a no-brainer for any Marrakesh shopping list. Inside the medina, argan products are not hard to find, but it can be hard to know which merchants are selling the real, unadulterated deal. My first suggestion, then, would be either to enlist a guide or visit a dealer you know to be legitimately government-approved. Otherwise, if you’re deep in the souk, keep an eye out for Assaisse Ouzeka, which sells legit argan products made by a women’s cooperative in the coastal town of Essaouira. Look for a slightly messy setup by the door with women demonstrating the oil-extraction process. (It’s apparently still done by hand everywhere, which strikes me as amazing.) Inside the tidy, well-lit shop, you’ll find everything from hair and skin oils to lip balm and anti-wrinkle cream. The salesgirl who helped us was very sweet and—a true rarity in the go-go souks, one sometimes feels—not too pushy. I wish I could be more specific about where the shop is, but anyone who's been in the souks knows what a labyrinth they are!
