PS: What product defines your brand?

TH: One product I'm very proud of is Elixir Vitae ($400). It's a supercharged product formulated to act like an injectable but topically. It works to reduce the appearance of wrinkles by helping smooth the skin's surface and filling the look of fine lines to restore the appearance of youthful plumpness and volume. It's the ultimate antiaging product.
