Nutox Serum Concentrate is Nancy Wu’s favourite Nutox product. This is an enhanced, concentrated serum packed with two times more bird’s nest collagen that will help to defy ageing. This lightweight serum is boosted with Actigenics Technology™, which help to improve gene activity and speed up the production of the skin’s natural collagen, elastin and hyaluronic acid. Be amazed by its instant and long-term lifting effects. The result of consistent use is visibly improved deep wrinkles in two weeks*. Your skin becomes firmer, elastic and smooth. It is suitable for all skin types.
