It may be a little unusual for a member of the nobility to become a noted beauty entrepreneur, but that is exactly what Princess Theodora von Auersperg—whose Austrian lineage dates back to the early 1100s—has done. Having battled with her own sensitive skin over the years, Auersperg realized the same ancient beauty secrets used by her ancestors are still effective for women today. The cornerstone of her organic and vegan handcrafted recipes is the rose: Nearly every product is packed with nutrient-rich rose oil and/or healing rose water—without smelling like an overgrown garden party. My star pick is the Rejuvenating Rose Serum, a lightweight potion that refines skin texture while diminishing fine lines and increasing hydration.

Bonus: Princess von Auersperg’s products don't use genetically engineered ingredients, and everything is manufactured and packaged in the United States.
