Spermine, a powerful anti-oxidant originally discovered in, yes, human sperm, is said to diminish wrinkles and smooth the skin. The substance is now being synthesized in laboratories and sold by a Norwegian company called (seriously) Bioforskning. Spermine facials (really) cost $250 at Townhouse Spa, where the substance is penetrated with ultrasound and infrared light (a more basic treatment can be found for $125 at the nearby Graceful Services). Also available at Townhouse for $175: snail-secretion facials.
