England loves a golden crown—and gold-infused spa treatments. Nobody does the latter better than the Dorchester, whose elegant spa folds an array of gold-infused treatments into its menu, all exclusively developed by the anti-aging experts at Carol Joy London. The best is the Pure Gold and Collagen Facial, which begins with a pure collagen mask for the face, neck, and shoulders. Then, 24-karat gold leaf is layered over the skin and finished with a collagen spray. Designed to do away with dull complexions, the treatment reveals youthful skin that is truly brilliant.
