Founded in 1867 as an apothecary shop—its specialty back then were such magic potions as “Money Drawing Oil”—it switched to more modern snake oil, facial creams, and cleansers in the 1960s and has been wildly popular ever since. (In fact, it's now a multinational chain). Still, this is the original store and it's worth it to visit for its historic decor (the original chandeliers are still in use) and the generous gift of numerous small samples.
