The U Beauty's formulas feature proprietary SIREN Capsule Technology. Unlike most skincare that release actives all over the skin, SIRENS avoid impacting healthy skin by luring damage-causing free radicals to it like a magnet. By keeping key actives localized to damaged areas and away from healthy skin, The U Beauty products accomplish quicker results and help to avoid irritation while optimizing skin’s collagen, elastin, and hyaluronic acid.
