Gold: a precious metal, a coveted jewelry material, a highly effective heat reflector, and now it is the key ingredient in two new cosmetics lines. Promising youthful, glowing skin; an increase in elasticity and blood circulation; not to mention treatment from sun damage, inflammation, and skin allergies, the 24-karat-gold products by Euphorie and Le Royal claim to be many things to many people. We’ll see. The company says the gold-infused skin-care products are loaded with powerful antioxidants and offer protection against free radicals—just the thing to pamper, rejuvenate, and illuminate your face. Just don’t leave it on too long lest you end up like Shirley Eaton in Goldfinger. (leroyal24k.com, luxurycosmeticbrands.com).
