Advanced AHA with LCA Complex™ works by improving skin health and fitness through internal moisturisation of the skin and by improving skin exfoliation. Both skin moisturisation and exfoliation decrease with the natural ageing of skin, leading to "normalized" skin function and better skin health, returning the skin to a more youthful healthy-looking appearance. Priori Advanced AHA with LCA complex™ Gentle Facial Cleanser gently cleanses and exfoliates the skin, without compromising skin barrier function. Leaves skin soft, smooth and radiant.
